摘要

牛心柿及石柿二品種於盛花期噴施GA3及BA，結果發現BA對牛心柿著果率及結實率影響不大，GA3則可提高著果率及結實率，其中GA3 25 ppm，50 ppm及100 ppm效果可達5%顯著水準，二種植物生長調節劑對石柿則均有顯著提高著果率之效果。處理後第二年植株枝條生長與開花受前一年處理之影響不大，在果實性狀及品質方面，除製柿餅後澀味以對照組明顯較高外，其餘各處理間差異均不顯著。

This experiment was conducted at Peipu to study the effect of plant growth regulators on fruit set ratio, fruiting ratio and fruit characteristics of two local varieties (Diospyros kaki L. cv. Niou Sin and Diospyros kaki L. cv. Shyr).Six treatments including 5 ppm and 10 ppm BA, 10 ppm, 25 ppm, 50 ppm and 100 ppm GA3 were used during the full blooming. In cv. Niou Sin persimmon trees showed only GA3 gave promotive effect on fruit set and fruiting ratio, whereas cv. Shyr persimmon trees, showed not only BA but also GA3 increased fruit set and fruiting ratio, there was no siginificant influence on shoot growth and flowering in next year spring.There was no significant difference on fruit characteristics and quality among treatments. However, the fruit of control gave higher astringent taste than other treatments when processed as dried fruit.
