【Major features】
The new variety “Reikou” is desired to cultivate citrus varieties that mature after the beginning of the year in order to improve the varieties of citrus fruits in Japan, which are biased toward the production of Satsuma mandarin that matures within the year. It is a variety made for the purpose of peeling citrus varieties with high sugar content and good taste. It is loved as a tangor of Nakate, which was bred by crossing “Kiyomi oranges / Angkor No. 5 oranges” with “Murcott oranges”, but its appearance is red-orange, smooth and beautiful. It has aroma, high sugar content and good taste. Male sterility (In the “cytoplasmic-only type” in which male sterility is controlled only by the cytoplasm, mitochondria, which are organelles of the cytoplasm, cause male sterility, and this male sterility indicates maternal inheritance. Protoplast culture. Male sterile mutants that emerged from the genomic mutations that occur in the plant are known. Some plants have and do not have a gene that does not produce pollen in mitochondria, and some have a gene that suppresses its action in the nucleus. Among them, in wild plants, the combination in which mitochondria have the property of male sterility and the nucleus suppresses it has evolved, and in cultivated plants, the combination in which mitochondria do not have the property of male sterility and the gene that suppresses it in the nucleus has developed. And, the combination of wild and cultivated species by humans has created a combination in which mitochondria have the property of male sterility, but there is no gene to suppress it in the nucleus. This is the mechanism. Mitochondria（The Origin of The Origin of by Lynn Margulis, the first wife of astronomer Carl Edward Sagan, who suffered a hemorrhagic cerebral infarction on November 17, 2011 and died at his home in Amherst, Massachusetts on November 22, 2011. Mitosing Eukaryotic Cells; In 1967, aerobic bacteria such as proteobacterium parasitize the cells that are the predecessors of eukaryotic cells, and it seems that they have settled down to the present form through subsequent symbiotic evolution. For example, the fact that a genome independent of the nucleus (called mitochondrial DNA) exists in mitochondria and that it has a double membrane structure not found in other organelles means that this organelle is other than the cell body. It is associated with the origin of another organism. Prior to Margulis, Russian researcher Konstantin Mereschkowsky showed that a 1905 paper had already proposed the endosymbiotic theory (his own book “Symbiogenesis and the Origin of Species”). She wrote her dissertation in 1967, and her book “The Origin of Eukaryotic Cells” in 1970, quite a few years later. In these, the theory revolves around the evolution of mitosis in eukaryotes.）Is an organelle associated with breathing and synthesis of ATP (Adenosine triphosphate: C10H16N5O13P3), but the gene for male sterility is breathing and ATP (all plants, animals and microorganisms (including food, bacteria, molds and other microorganisms). It is an energy molecule that exists in cells (often in the immediate vicinity of genes for organic synthesis and acts to inhibit them). Cell proliferation, muscle contraction, plant photosynthesis, fungal respiration and yeast. It is a compound used by all organisms to supply energy to metabolic processes such as fermentation. It does not seem to be affected by this gene at the stage of plant growth, but it interferes with the stage of pollen production. However, since enormous energy is required to make pollen, if the functions of breathing and ATP synthesis are suppressed, it will not be possible to make pollen well.) However, the seed-forming ability is strong. Therefore, in order to obtain non-nuclear fruits and low-nuclear fruits, it is recommended that varieties that form pollen are not planted in the surrounding gardens. In addition to the high quality in appearance and content under facility cultivation. , It seems that it becomes a non-nuclear fruit and does not become a high-waisted fruit. Creating the future of agriculture and the region through further practices of self-reform / At the 30th JA Saga Prefectural Convention (May 16th), we have decided on an initiative policy for the next three years from FY2019. While issues such as the weakening of agricultural production bases and the decline of living infrastructure functions are becoming apparent due to age and population decline, it seems that further practices of self-reform will create the future of agriculture and the region. Based on the situation and issues surrounding JA Group Saga and the progress of the implementation of the matters resolved at the previous convention, we resolved six measures that will be the key to future directions and implementation. As with the previous tournament, it seems that the resolutions of the tournament will be positioned as self-reform efforts, and various measures will be taken to realize the vision of JA Group Saga. Based on the future outlook of regional agriculture, it seems that it will strive to expand sales of agricultural and livestock products that capture demand, foster new farmers, etc., and further work to increase the income of farmers and expand agricultural production. It is said to be a diligent application to contribute to the creation of safe and secure local living and regional revitalization through JA's comprehensive business and lifestyle and cultural activities. Strengthen membership by promoting business use and participation in cooperative activities according to the diversifying actual conditions and needs of union members, reflecting the intentions of union members and participating in management. Positioning public relations as an important pillar of management strategy, it seems that it will develop various public relations activities, aim for public understanding of food, agriculture, and cooperatives, and work to establish and strengthen a sustainable JA management base. In addition, it seems that evaluations from union members and new needs through self-reform efforts, problem analysis, member surveys, etc. will be linked to improvement of JA management. The domestic grapefruit “Sagan Ruby”, which is rare in Japan, is harvested every year in Karatsu City. “Sagan Ruby” is a grapefruit that was researched and developed by the Faculty of Agriculture, Saga University about 33 years ago, and was registered as the first variety in Japan in 2013, about 9 years ago. At the house of about 5 ares in the Hada district of Karatsu city, it seems that the Kagami Fruit Agricultural Cooperative in the district has been cultivating for about 18 years. According to the Kyoka Fruit Agricultural Cooperative Association, there are currently two cultivated “Sagan Ruby” in Karatsu City and one in Kashima City. The number of producers is steadily increasing, and the cultivation area will continue to expand. A citrus variety developed by the Faculty of Agriculture under the university brand of Saga University (Saga City, Saga Prefecture). It is a citrus fruit similar to grapefruit, and it is cold-resistant and easy to grow in Japan. It seems that efforts are being made with the cooperation of the Saga Agricultural Cooperative Association (Saga City) and local farmers. “Sagan Ruby” was registered as a trademark in April 2008 (No. 5131519). The right holder is Saga University, a national university corporation. Kuchinotsu, Minamishimabara City, Fruit Tree Experiment Station, Citrus Club (Kuchinotsu, Minamishimabara): It takes about 15 years to develop and nurture. Friends of Nagasaki Koi（Yearning）Mikan（Mandarin）; “Setoka” : It is famous as a tangor that was bred by crossing “Murcott” with kiyomi with Angkor No. 2 of the breeding system. A small-nucleus variety with large fruits, soft and juicy, aroma, high sugar content and good taste. Middle-aged Citrus L. matures from January to February. The fruit surface is smooth, the fruit shape is oblate with a high waist, and the skin is orange to dark orange. Thin, easy to peel, with a medium aroma similar to Angkor or Murcott. The flesh is dark orange, the sac is thin, the flesh is soft and juicy, and the number of seeds tends to be small, about 0-5. And it seems that parthenocarpy（Ovary wall and flower bed enlarge and form fruit without fertilization）is strong. The fruiting is good and it is easy to get results every year. Strong tendency to streptomyces spp., Xanthomonas campestris pv. citri. It is Susceptibility against citrus tristeza virus (ctv), and the incidence of stem pitting（Easily propagated by Toxoptera citricida Kirkaldy, and also propagated by cotton aphids at a low rate）is high. Since one ball is heavy, it is necessary to manually support it so that the branches do not break due to its own weight as it grows. Application No. 10852 Date of application 1998/04/09 Date of publication of application 1999/03/18. Registration number 9398 Registration date 2001/10/18. Plant Variety Protection and Seed Act, Act No. 83 of May 29, 1998 : 25 years of breeder's rights ; National Agriculture and Food Research Organization, NARO.Unique sweetness, chewy texture, and wonderful fragrance. Citrus “Three great elements.” The history of Nagasaki mandarin is that in 1780, the Omura feudal lord, “Sumiyasu OHMURA”, the Satsuma feudal “Nagashima mandarin” (Izumi District (former: Azuma Town) Nagashima-cho, Wenshu mandarin), and Ikiriki Village, Nishisonogi District (currently Isahaya). It is said that the cultivation was started by Mr. Yuiemon Tanaka, Mr. Rinemon Tanaka, and Mr. Tsuguemon Nakamichi of the city, formerly Tarami Town, Nishisonogi District.（Citrus Unshiu has heard that the seeds brought back from China by the envoy to Tang China began to bear fruit and were found in Kagoshima. High-quality “Satsuma mandarin” was cultivated from the Ikiriki region, and saplings began to be shipped nationwide, and it is called “Ikiriki-based Satsuma”. In 1876, it seems that oranges were sold by hand in the castle town. In addition, from around 1887, the production area of mandarin oranges was expanded in Ikiriki Village, and even today, the area is the main production area in Nagasaki Prefecture. From 1961, “Act on Special Measures for Promotion of Fruit Tree Agriculture (Government Ordinance No. 145)”, the Nagasaki Prefecture Citrus Promotion Plan was formulated, and the citrus cultivation area increased rapidly throughout the prefecture. Demand for fruit trees in Japan is generally declining and stagnant, and there is a growing tendency for small quantities to be sold as other items and for good quality. Many fruits, including mandarin oranges, are in overproduction. There are increasing demands from other countries to expand imports of fruits and fruit products. In order to achieve sound development, it is necessary to deal with the overproduction trend of fruits. Induce production that responds to trends. Fostering independent fruit tree farmers who can be the core players in the production area. And it is necessary to further strengthen the constitution of fruit tree agriculture. The system for promoting fruit tree agriculture was strengthened（Partial amendment of Law No. 15, July 1, 1985）. From NARO, the fruit of Setoka is a large fruit of 200 to 280 g, the fruit surface is smooth, and the fruit shape is oblate with a high waist. The pericarp is orange to dark orange, thin and easy to peel. It has a medium aroma similar to that of Angkor or Murcott, and has a good taste with a ripening period of February and a sugar content of 12 to 13%. The flesh is dark orange, the sac is thin, the flesh is soft and juicy, and the number of seeds is small at about 0-5. It is also characterized by its strong parthenocarpy. The tree is medium to slightly weak, and the tree is medium to open. The fruiting is good and the results are planned every year. It is strong against Elsinoë fawcettii（Wart-shaped or scab-shaped lesions on leaves, fruits, and branches. Citrus unshiu is weak and rarely occurs in midnight citrus, but lemon is weak. Wart-type lesions occur by the middle stage of spring leaf elongation, and lesions occur even after the end of elongation. Wart-type lesions form up to 1 cm in diameter in fruits, and lesions form above that.）, Xanthomonas citri subsp. Citri（Occurs on leaves, green branches and fruits. The lesions on the spring leaves are initially round, pale yellow, and water-soaked spots, which later expand to cork in the central part and become rough, and the circumference 0.5 mm width is water-soaked and further around. Produces a fairly wide yellow halo. The lesions on the back of the leaves are also corked and rough, but it seems to be a light brown raised scab. In summer and autumn leaves, citrus leaf miner often invades through wounds such as feeding damage and wind sway, so it seems that lesions generally tend to form along the wound. The petioles are also easily affected and the leaves fall violently. On the fruits and green branches, water-soaked dark green lesions are formed at first, and then they become cork and become light brown raised scabs. Overwintering lesions on leaves and branches are the primary source of transmission, but lesions on treetops in summer and autumn are especially important. In addition, in Spring cankers infected at relatively low temperatures in autumn, the amount of pathogenic bacteria released is even higher than in the lesions of summer-autumn treetops, making it more important as a source of transmission. The leaves are infected with stomata from the new leaf development stage to the growth arrest stage, and then when the tissue hardens, it is infected from the wound caused by the wind and the feeding damage scars of Phyllocnistis citrella. The main infection period for spring leaves is from early May to mid-June. Following the infection of spring leaves, it seems that the infection is repeated to spring branches and summer and autumn treetops. Infection of fruits is from immediately after flower fall to late September, mainly by secondary infection from leaves. Winds and rains accompanied by strong winds with wind speeds of 6 to 8 m or more, especially typhoons in summer, are the most important factors that promote the onset of disease. There is a difference in resistance depending on the type of citrus, and I heard that Satsuma mandarin is moderate.）, is susceptible to citrus tristeza virus (CTV), and seems to have a high incidence of stem pitting. As an aside, the mid-late citrus “Setoka” seems to produce a certain amount of softened fruits with low sugar and high acidity, mainly in greenhouse cultivation. Greenhouse-grown “Setoka” is often sold as a high-class fruit in units of one, and it seems that such low-quality fruits may rarely be subject to complaints from consumers. The quality of softened fruits during the harvest period is slightly smaller than that of normal fruits, the skin color is yellow, and the skin is thin. It seems that the fruit surface is smooth and the fruit is soft. Brix in fruit juice is about 30% lower than normal fruit, and acid seems to be about 40% higher. Fruits two months before harvest, which is the coloring period, tend to be late in coloring. Regarding the details of the components in fruit juice, fructose, glucose, and sucrose that make up sugar are all low, and sucrose, which is the main sugar, is about 70% lower. In addition, the content of almost all amino acids composed is low, and the total amount of all amino acids seems to be about 30% lower. The incidence rate by fruit set site is particularly high in the inside, and it seems that it is estimated to be about 12%. The incidence of other parts is 1 to 4%, and it seems to be about 3% on average. In the fruit of softening disease, the photosynthetic product made from the leaves did not transfer from the fruit stalk (fruit axis) to the fruit by the experiment using the stable isotope of carbon, and the phloem (fruit axis) by microscopic observation. It has been confirmed that callose (β-1, 3-glucan), which is a kind of polysaccharide, is accumulated in the phloem in the fruit stalk). It seems that callose blocks the phloem and inhibits the translocation of photosynthetic products to the fruit, leading to quality deterioration. It seems that the methods to prevent the shipment of softened fruits are to remove the inner fruits as much as possible at the time of fruit picking and to pick small fruits that are late in coloring during the coloring period about 2 months before harvesting. In addition, it seems that fruits that are slightly softened by small balls that are yellowish compared to fruits with a normal appearance are excluded at the time of harvesting or home sorting. If a joint fruit sorting plant with an optical sensor is available, it seems effective to eliminate fruits with low sugar content. Consumers should choose a uniform color, a smooth surface, a glossy surface, and a bluish tint on the calyx. Also, the ones that feel heavy when you hold them are delicious with a lot of juice. The shape may be more delicious if it is flat than if it is tall. In 1984, at the fruit tree test site Kuchinotsu branch: Present: Minamishimabara City (currently the Fruit Tree Research Institute Citrus Research Division (Kuchinotsu, Nagasaki Prefecture)), a strain developed by crossing “Markot” with “Kiyomi” and “Angkor No. 5”. In 1986, he was highly connected to Unshu Mandarin and first fruited in 1989.（Middle-aged Tangor）1996年4月よりカンキツ第8回系統適応性, 特性検定試験を実施.（The fruit is oblong and the peel is pale reddish orange to dark orange. The hardness is moderate, and peeling is rather easy.）When you look at the record and show the features that it's worthy of the agreement. The appearance of the tree is in the middle position, the size and vigor of the tree, the thickness of the shoots, the internode length and the degree of shoots in the shoots are moderate. “Omitting” The fruit juice is high, the sweetness is high, the sourness is medium, the flavor is high, the number of seeds is small, and the number of embryos is multi-embryo. 国立研究開発法人農業・食品産業技術総合研究機構 : 茨城県つくば市, Application for registration was made in 2003, and breed registration was made in 2005. It was registered as “Tangor Norin No.9" on January 26, 2004 and also registered as No.13542 under the Seed and Seedlings Law of Japan on December 7, 2005. Compared to “Setoka”（Different strains are registered as different varieties with the same cross）and “Markot”, distinctiveness is recognized due to the fact that the fruitfulness is large and the maturity period is early. Hamatama Fruit Sorting Ground : Sugar content and acidity meet the standards, and select products with excellent appearance and sell them as “Hamasaki（It's a little reddish, bright orange, and is said to have been named for the precocious oranges that have been around since the Lunar New Year. The Hamatama Fruit Sorting Plant is located in “Hamasaki, Hamatama Town”, Karatsu City, Saga Prefecture. Content and acidity meet the standards, and select products with excellent appearance and sell them as “Hamasaki”.）”. The shipment period starts around February, and peaks at around March, with a short period and high value. Karatsu City, Saga Prefecture, is renowned as a leading production area and reminded me of my classmate, who was my own son-in-law. Fruit skin is from light red orange to dark orange. Approximately 2.3 mm thick Inside and outside, it is thin, but the hardness is medium and peeling is a little easy. The fruits are oblate and cute. The fruit surface is smooth and completely colored from late November to mid-December, making it difficult to fade. The flesh is dark orange, the flesh is soft, and the amount of juice is large. Segment membrance is relatively thin and easy to eat, the sugar content of fruit juice is high at about 12 %, and acid reduction is relatively easy. It has a fragrance like a mixture of Orange and Murcott Tangor, and has a good taste and is refreshing. It has a male sterility and no pollen, so it is non-nuclear unless pollen of other varieties is applied. The maturity period is mid-January, which is earlier than ‘Iyokan’ and ‘Kiyomi’. The tree shape is between upright and open, with long shoots, medium thickness, and dense growth. In addition, the tree vigor is moderate. Thorns occur, but they are shorter and less frequent, and tend not to occur when the tree vigor settles down. The fruiting is relatively good, and it is strong against Streptomyces spp. However, it is recognized that it is somewhat susceptible to canker（Xanthomonas campestris pv. citri）disease. I have heard that the degree of stem pitting caused by Citrus tristeza virus is high. I forgot, because I don't make pollen myself, I can't get seeds unless I'm pollinated by pollen of another variety. “Karatsu City, Saga Prefecture” : The Ariake Sea facing Saga Prefecture (enclosed in the four prefectures of Saga, Fukuoka, Nagasaki, and Kumamoto. The area is 1,700 km2, which is almost the same as Tokyo Bay and Ise Bay. Especially, the Ariake Sea facing Saga Prefecture is a very shallow sea. Even at the deepest point, the depth is only about 20 m. The tidal range (the difference in depth between when the tide is low and when it is full) is the highest in Japan, and it is more than 6 m.) Useful for activities: ITO EN, LTD., A major beverage manufacturer, wants to be useful for activities to protect the abundant nature and environment. (Headquarters location: Honmachi, Shibuya Ward, Tokyo, Factory: Shizuoka Sagara Factory (Mekami, Makinohara City, Shizuoka Prefecture), Kobe Factory (Mitsugaoka, Nishi Ward, Kobe City, Hyogo Prefecture), Hamaoka Factory (Niino, Gozenzaki City, Shizuoka Prefecture), Fukushima Factory (Fukushima Prefecture) Araikita, Fukushima City), Okinawa Nago Factory (112, Isegawa, Nago City, Okinawa Prefecture), Research Institute Central Research Institute (Mekami, Makinohara City, Shizuoka Prefecture) established, August 22, 1966) seems to have donated a part of the sales to the prefecture. On February 7, 2022, it seems that he handed over a list of 200,000 yen to Vice Governor Sakamoto of the prefecture. ITO EN, LTD. Then, it is making efforts to donate a part of the sales to environmental conservation and maintenance activities in various parts of Japan, and it seems that this is the 10th time in Saga prefecture, and the total amount is 2.86 million yen. I heard that this donation is a part of the sales of the main product “Oi Ocha（Green tea）” in the prefecture during the campaign period from August 23 to October 3, 2021. ITO EN, LTD. The male manager of the Chugoku-Shikoku / Kyushu Regional Sales Headquarters seems to have said that he would be helpful (in activities to protect the environment) because he sells products that are closely related to nature and water. In the prefecture, the donations donated were used for the conservation and regeneration of the Ariake Sea and Nijinomatsubara (Matsubara, which is connected like a rainbow arc along Karatsu Bay. The pine tree, which has a total length of about 4.5 km and a width of about 500 m, has about 1 million pine trees. It seems that it will be useful for the preservation of (designated as a scenic spot). It is located in the northwestern part of the prefecture. The city area covers about 36 km east-west and about 30 km north-south, with a total area of about 487.60 km2. It occupies about 20% of the whole prefecture. The eastern part of the city is Itoshima City and Saga City, Fukuoka Prefecture. The southern part is Taku City, Takeo City, and Imari City. The western part borders Matsuura City, Nagasaki Prefecture, separated by Genkai Town and Imari Bay. The northern part faces the Genkai Sea. In the eastern part, the Sefuri mountain range slopes gently toward Karatsu Bay. The central part has a flat part along the basin of the Matsuura River, and the western part has a hilly Uwaba plateau. Karatsu Bay, which forms the land, has strip-shaped Matsubara and sandy beaches on both wings, and Takashima is located in the center of the bay. etc. Agriculture : Early paddy field remains including continental ground stoneware and carbonized rice were concentrated and discovered in the northern Kyushu region, such as the Itazuke site located at Hakata Ward, Fukuoka City, Nabatake site located at Karatsu City, Saga Prefecture, Magarita site located at Fukuoka Prefecture and Notame site located at Fukuoka Prefecture. The essence of art that connects the modern era to the future. Traditional ceramic art of ‘Karatsu ware’ dates all the way back to the Momoyama period. In the beginning of karatsu ware, cloudy straw ashes glaze was used frequently. But after the Meiji Restoration, karatsu ware lost the clan's patronage, and the number of kilns which canceled production increased, they doubted whether it continued. ‘Ichiraku 2 Hagi 3 Karatsu’ : Designated as a traditional Japanese craft along with the branch Takeo Kokaratsu ware. Tadazane's younger brother, the Lord of the Mikawa-Yoshida Domain (present-day Toyohashi City, Aichi Prefecture), and Tadatomo OGASAWARA (whose descendants were lords of Karatsu Domain, Hizen Province [present-day Karatsu City, Saga Prefecture] at the time of the Meiji Restoration) invited Sohen Yamada, one of the 'Four Heavenly Kings' (as the closest followers of the founder of the Sansen FAMILY（Omote, Ura, Mushakoji（Kankyu hermitage））tea ceremony, SEN no Sotan, were known), to revive the matcha ceremony, though separately from the Ogasawara style. TADAZANE（Shimousa Country Koga Castle : Mr. Fuchu OGASAWARA）stayed the position as the lord of the Kokura Domain until the end of Edo period and the line of TADATOMO which was relocated to some places, was finally relocated to the Karatsu Domain, Hizen Province (presently Karatsu City, Saga Prefecture) holding 60,000 koku（of rice) (a unit of volume: rice 1-koku is 180.39 liter, lumber 1-koku is 0.278 cubic meter）and the line of Nagatsugu was finally relocated to the Anji Domain, Harima Province (presently Himeji City, Hyogo Prefecture) holding 10,000 koku（of rice) (a unit of volume: rice 1-koku is 180.39 liter, lumber 1-koku is 0.278 cubic meter）as the result of change of rank due to misrule and extinction of the family line. Now, let's return to the story of mandarin oranges. This is a bud mutation of Wase Miyagawa found by Hisahiko UENO（Wase Ueno Citrus Unshiu）of Hamatama Town, Higashimatsuura District, (today's Karatsu City,) Saga Prefecture in 1970, and was registered as a new variety in 1985. Also, It is a bud mutation of Wase Miyagawa found by Mr. Hirofumi MORITA（Morita Citrus Unshiu）of Nanayama Village, Higashimatsuura District (today's Karatsu City,) Saga Prefecture, and was registered as a new variety in 1980. A long-established company that the city is proud of Miyajima Soy Sauce Co., Ltd. (founded a soy sauce brewery in Karatsu City, Saga Prefecture in 1882. About 140 years of continuous production of soy sauce and miso, which can be said to be the origin of Japanese food. It is said that he continues to seek more delicious, rich and reliable taste while responding to the voices of people and the times. Based on traditional fermentation technology, various sauces, powdered soy sauce, liquid soy sauce, brewed meat sauce, etc. It seems that it has expanded the range of food manufacturing technology to noodle soup, dressing, spices, canned foods, retort foods, frozen foods. Creating the future from the origin of deliciousness.) Is a short movie, delicious is connecting omoi. Will be delivered from 12:00 on January 13, 2022 (Thursday). The concept of the image is delicious, but it seems to connect thoughts. An excellent older sister who is loved by everyone. She has mixed feelings about her sister and she hates her sister. The lunch box that her sister cooks with her thoughts gently draws the heart of her sister who has left her. And the taste of her sister's bond was the taste of her mother, who had long been accustomed to it. Delicious is something that connects people's feelings. It seems that the “family bond” is expressed through the story of the sisters. With the idea of “connecting people and supporting people's happiness through food,” this work, delicious, connects people's thoughts. Was produced.
The appearance is red-orange, smooth and beautiful, fragrant, high sugar content and good taste. When it becomes an adult tree, it tends to be in a state of excessive flowering, so-called solid flowering, and as a result of the short time, there is a risk that straight flowers will grow densely on the mother branch and most of the fruits will fall. To secure fruit set, how to increase the ratio of foliage flowers, for that purpose, use a lot of pruning, and prepare a mother branch with more than 12 cm and 7 or more leaves, and to the foliage flowers. , It seems that the aim is to improve the fruit set rate by spraying gibberellin at the time of flowering. “Reikou orange” has a thin skin and is prone to cracking, and it is likely to occur under conditions of insufficient sunlight and excessive soil moisture, and countermeasures are difficult, but the higher the fruit shape index, that is, the flatter the fruit, the easier it is to crack the fruit. Occasionally, it seems that the outbreak can be reduced to some extent by leaving a slightly tall fruit.
Among Reikou, the ones with excellent sugar content and acidity that meet the standards and have an excellent appearance are selected. Excellent products are shipped as “Hamasaki oranges”.
