【摘要】 在葡萄生产中合理使用赤霉素,研究花前花后使用不同浓度赤霉素对葡萄果粒性状及品质的影响。结果表明:花前5d用50mg·L-1+花后9d用200mg·L-1的赤霉素处理可有效的增大果粒纵横径,进而增大果粒重和产量。喷施赤霉素,还可使鲜果硬度增大,耐贮运性能增强。更多还原

【Abstract】 In order to reasonably use gibberellic acid in grape production,taking Thompsons seedless as test material,the effect of different concentration of gibberellic acid on fruit character and quality of grape were studied.The results showed that the application of 50mg·L-1 GA3 before blooming+200mg·L-1 GA3 after blooming could significantly increase the vertical and transverse diameter,fruit grains weight and yield.Furthermore,it could increase hardness to improve tolerance to storage and transportation.更多还原
