摘要
以东山月拔和二十一世纪这 2个品种为试材 ,研究了番石榴 (PsidiumguajavaL)果实的发育动态规律。结果表明 :番石榴的果实发育呈现双“S”型 ;果实重量和果核重量的发育呈显著的正相关 ;推测果实发育后期为进行果实产期调控的关键时期 ;建议以果实发育的直径大小以及果实转蒂下垂作为确定进行产期调控的田间依据。
Fruit development of Guava (Psidium guajava L.) in cultivars`Dongshanyueba'and `21 century' were studied. The results were as follows: The fruit growth showed the double sigmoidal pattern, Obvious correlation was found between fruit weigh with fruit core weigh in the fruit growth. We thought the later period of fruit development was the key period for regulating the fruit maturation. Suggestion to regard the diameter of fruit development and drop of fruit as one of the evidence which regulated the fruit maturation.
