摘要: 巨峰(Vitis vinifera × Vitis labruscana Bailey)及蜜紅(Vitis vinifera ×Vitis labruca L. )夏、 冬兩收葡萄果實生長曲線均為雙 S型,其冬果生育日數各約90及80天,夏季葡萄有較短之情形。在硬核期 方面,巨峰夏、冬果分別於滿花後32∼39日及27∼34日進入硬核期。除蜜 紅夏果外,一般硬核期均維持14天左右。滿花後46日,夏果果實可溶性固 形物開始上升,可滴定酸及硬度下降,並進入第二生長期,而冬果則於滿 花後41∼48日開始變化。兩品種夏果之體積、鮮重均大於冬果。不同種子 數果實其生長曲線有不同之現象,1個種子之果實與2個或3個種子果實 差 別較大;種子數與成熟期之果實硬度、可溶性固形物及可滴定酸變化較快 。兩個種子的巨峰及蜜紅夏果果肉之細胞於滿花後15天左右停止分裂,而 巨峰冬果於滿花後10天左右停止;蜜紅 於滿花後5日左右完成細 胞分裂 。巨峰果肉細胞分裂之最大速率約發生於細胞停止分裂前 5日左右。兩品 種在果實成熟時夏果之果肉細 胞為23∼24層,冬果果肉細胞則為20層左 右。果肉細胞大小方面,其夏果果肉細 胞大小為230∼250μm,而冬果則 為250∼270μm。
The growth pattern of summer and winter grape berries in both of ''Kyoho''( Vitis vinifera × Vitis labruscana Bailey) and ''Honey Red''(Vitis vinifera × Vitis labruca L.) showed double sigmold curve. It took 90 days for ''Kyoho'' as well as 80 days for ''Honey Red'' to develop, respectively. During 32~39 days afterfull bloom, both of summer and winter grape of ''Kyoho'' reached the veraison. However, ''Honey Red'' reached the veraison time during 27~34 days after full bloom. Generally, the duration of the veraison was 14 days, expect the summer grape of ''Honey Red''. From the 46th dat after full bloom, the total soluble soids increased, acidity and firmness decreased in the summer grape. And it was viewed that the berries entered the second growth stage. Nevertheless, the changes of the total solube soids, acidity and firmness in the winter grape were occourred 41~48 daysafter full bloom. In both cultivars, the berry volume and fresh weight were larger in summer. The berry growth patterns of different seed numbers appered different , and the difference between 1-seeded berry and 2 or 3-seeded berries were moresignificat. There wae no significant relationship between seed numbers and fruit firmness, total soluble soids and acidity at the harvest time, but the changes appered fasterthan those of 1-seeded berry during the fruit ripening.The pulp cell division were ceased aronud 15 days after full bloom in summer grape of ''Kyoho'' and ''Honey Red'', and winter grape ceased around 10 and 5 days after fullbloom for ''Kyoho'' and ''Honey Red'', respectivly. In both ''Kyoho'' and ''Honey Red'', the number of cell layers of summer grape was 23~24, and that of winter grape was about 20. The cell size was 230~250μmin summer grape and 250~270μm in winter grape.
