Abstract

In the early medium stage of differentiation,nucleic acid content in male buds is higher by 17% and 33% than that in female buds and leaf buds.In late stage,the content in male bud decreases while in female ones it increases.RNA/DNA ratio is 2~3 in early stage and 5~6 in Iate stage.There's no remarkable change in Protein Ievel.16 free amino acids can be found in various flower buds,among which Proline content is always very high and is closely related to flower bud in intiation and development.GA3 levels(FW)are as high as 50~90ugg-1 while ABA is as low as 1ugg-1 in the initiation of male buds。During the differentiation of female buds,GA3 and ABA are only a little.lower than those in leaf buds and their changes are mild.During flowering,feamle ABA notably decreases while male ABA greatly increases and GA3 decreases.
