| 摘 要： | 本研究测定了荔枝果实发育期间内源激素含量的动态。结果表明果实发育前期细胞分裂素(CTK),生长素(IAA)含量较高;中期乙烯(Eth),赤霉素(GA),的含量较高,这与果实的生长发育及落果有密切相关。同时,果实发育前期应用外源CTK、中期应用GA、处理果穗可显著提高产果率。

| Abstract: | Contents of endogenous hormones in Litchi fruits (Litchi chinensis Sonn.Var.Hualzhi) were determined during fruit development The data showed that the contents of the cytokinind (CTK) and Indole-3-acetic acid (IAA) were higher during the early stages of fruit development.There were a peak of gibberellin4+7 rlevel and a peak of ethylene level at the second stage of fruit development.The fluctuations of these endogenous hormone levels were correlated respectively with growth ,development and drop of fruits.Treated fruiting panicles with CTK at the first stage or GA3 at the secod stage could increase the rate of fruit setting obviously. |
