Toki: A cultivar for tea that has good initial growth and quality.

[Developer] Uji City • Jinnohira Hirano, Kyoto Prefectural Tea Research Institute

[History] In the early Showa era, Jinno Hirano selected him from his own Uji traditional tea garden, and in 1954, passed a candidate primary tree performance comparison test (strain comparison test) at the Kyoto Prefectural Tea Research Institute. Registered. The old strain name is "Hirano No. 11," and the name of this variety is called "J with no brilliance, J like Asahi," "Refreshing J," or "pure green."

[Early-early] 4 days earlier than'Yabukita' in the sprouting stage, 1 day earlier than'Yabukita' in the early harvesting period-The same mesomorphic species Is. The new leaves are elliptical, slightly large, slightly pale, and green. The mature leaves are elliptical, large, slightly pale, green, and have a lot of gloss. The new shoots that are shielded from light are glossy and flexible. Unsatisfactory harvesting efficiency due to obtuse angle of elongation of sprouts

[Rooting of cuttings] It is a little defective because it is uneven, and it is inferior to'Yabukita'. At the cuttings, adventitious cells near the cut end tend to clump. Care must be taken when adjusting the cutting soil and water management. When properly managed, aboveground growth is vigorous.

[Good quality of initial growth] Good quality and early growth. Although the vigor of young trees is strong, uneven growth is likely to occur, so careful cultivation management is desired.

[Layering method] It is a natural variety and hand-picked variety that is pruned by conventional means.

[Yield] The yield is slightly low to medium because the difference easily occurs depending on the growth. However, it is possible to increase the yield close to that of'Yabukita' under good cultivation conditions.

[Quality] The quality of tea production is particularly excellent as tea. The appearance is bright green, well-stained, crisp, and soft. The inner quality has a mellow aroma and fragrance that impresses with excellent dignity.

[Cold resistance] Strong against red and blue withers and grows well even in cool mountain areas. However, since buds and sprouts before and after the germination stage are sensitive to low temperature, measures against frost frost are essential. 0 Pest resistance • Middle anthrax disease, slightly weak to ring spot disease.

[Suitable for cultivation] A soil with good air permeability and water permeability is desirable because it is vulnerable to overhumidity and leaves are easily yellowed, which is a symptom of stagnant growth and iron deficiency. Since buds and sprouts before and after the germination period are sensitive to low temperatures, it is better to avoid areas where frost damage is common. Since it is highly sensitive to shading and fertilization, it may cause growth inhibition. Avoid strong shading and excessive fertilization from the juvenile stage. Also, in order to prevent frost damage on the tops of the shoots and winter buds, fertilization should not be continued until the early autumn and early winter.

[Processing characteristics] Be careful not to steam too much, as the new leaves are thin, especially under shading.
