N-(2-氯-4-吡啶基)-N'-苯基脲(CPPU)对甜柿果实中淀粉、还原糖含量和淀粉酶活性的影响

Influences of N-(2-chloro-4-pyridyl)-N'-phenylurea (CPPU) on Starch,Reduc-ing Sugar Content and Amylase Activity of Non-astringent Persimmon(Diospyros kaki Linn)

柿子品种‘卫郎’和‘禅寺丸’花后10d的果实喷施N-(2-氯-4-吡啶基)-N'-苯基脲(CPPU)后,果实中的还原糖含量增加,淀粉含量减少,淀粉酶活性显著提高。

For 10 d after full bloom, the reducing sugar content in the fruit of persimmon （Diospyros kaki Linn） cv. ＇Zenjimaru＇ and ＇Jiro＇ applied exogenous CPPU was increased, the starch content reduced, and the amylase activity increased.
