采用不同激素在不同时期和时间间隔处理金花茶花蕾的方法研究外源激素对花蕾生长的影响。结果表明，用１０００ｍｇ·Ｌ－１的赤霉素（ＧＡ３）处理直径在０．３２～１．１２ｃｍ范围内的金花茶花蕾，可以明显地促进花蕾的生长而无伤蕾现象。在抽梢前用ＧＡ３隔天处理，一个月后促进效果可达１００．７％，而用激动素（ＫＴ）处理则普遍抑制花蕾的生长。在抽梢后每周处理一次，则ＧＡ３的促进效果较差，一个月后促进效果只有４８．５％，而ＫＴ处理反而表现出一定的促进效应

The effect of exogenous hormones on flower bud growth was studied by using different hormones to treat Camellia sinensis flower buds in different periods and time intervals. The results showed that the treatment of buds with diameter from 0.32 to 1.12 cm with GA3 of 1000 mg · L-1 could obviously promote the growth of flower bud without injury bud injury. Treatment with GA3 for the next day prior to shoot tip showed a promotion effect of up to 100.7% after one month, whereas KT treatment generally inhibited flower bud growth. The treatment with GA3 was less effective after treatment once a week, and the promotion effect was only 48.5% after one month. However, KT treatment showed a certain promotion effect
