内容 キウイフルーツ'ヘイワード', 'アボット', 'ブルーノ', 'モンティ'及び'グリーンシル'の果実の発育が, 開花期より成熟期に至るまで形態学的に調査された.果実の生長を果重で表わした場合, いずれの品種の果実も明らかに3つの生長周期があり2重S字型曲線を描いた.すなわち, 果実が急速に生長する第1期は約60日間, 果実の生長が緩慢となる第2期は約30日間, また, 果実の生長が再び盛んとなる第3期は約75日間であった.外壁, 内壁及び果心組織の細胞分裂停止期は, それぞれ開花後24〜30日, 18〜30日及び15〜18日ごろであり, いずれの品種も内部組織ほど早く細胞分裂が停止する傾向にあった.細胞分裂停止期の各組織の細胞層数は, 外壁で49〜62, 内壁で29〜39, 果心で27〜53であった.また, 外壁組織の細胞の肥大は, 細胞分裂の停止直後から急速に起こり, 第1期の終わるころまで続いた.その後の肥大は成熟期に至るまで緩慢であった.
The morphology of fruit growth of Chinese gooseberry (cv. 'Hayward', 'Abbott', 'Bruno', 'Monty' and 'Greensill') from full bloom to maturity was studied. The growth curve of fruit in five cultivars obtained from the data concerning the increase in fresh weight of fruit was double sigmoid, and three distinct growth stages (I, II and III) were identified. Stage I, a period of rapid increase in fruit weight, was for about 60 days, Stage II, a period of delayed increase in fruit weight, was for about 30 days and also Stage III, a period of rapid increase again in fruit weight, was for about 75 days. However, the growth curve of fruit, as measured by increase in fruit diameter, was not double sigmoid. The last cell division in outer pericarp, inner pericarp and central core of each cultivar occurred 24 to 30 days, 18 to 30 days and 15 to 18 days after full bloom, respectively, and cell division ceased earlier in the inner tissue than outer tissue. The number of cell layers in each tissue at the time of termination of cell division was 49 to 62 in outer pericarp, 29 to 39 in inner pericarp and 27 to 53 in central core. The enlargement of cells in outer pericarp of 'Hayward' fruit occurred very rapidly after the time of the last cell division and continued until the end of Stage I. After Stage II, it was slow until the fruit reached maturity.
