摘要
以京亚和京秀两个葡萄品种为试材,以膨大素处理葡萄果实,结果表明:以花后15 d、浓度10 mg.kg-1的效果为最好。京亚和京秀两个品种座果率增加16.8%和10.3%;单果质量增加36.7%和28.7%;穗重增加47.9%和25.7%;果形指数减少0.036和0.048。果实中可溶性糖、有机酸和维生素C含量略有下降,增加果实的糖酸比。果实前期赤霉素含量增加,增加了果实的座果率;脱落酸含量的提高促进了代谢库细胞对同化物的吸收。
Took two grape varieties Jingya＇ and Jingxiu＇ as materials, the experiment of grape fruits treated by swelling agent was conducted. The results were as follows .. The best treatment of swelling agent was 10 mg· kg^-1 and 15 days after bloom. The average fruit-setting rate of Jingya＇ and Jingxiu＇ increased 16.8% and 10. 3%,respectively. The average single cherry weight increased 36.7% and 28.7 %, respectively. The cluster weight increased 47.9% and 25.7%, respectively. The average fruit shape index decreased 0. 036 and 0. 048, respectively. The treatments of swelling agent reduce the solvable content, acid content and vitamin C content,increase sugar acid ratio, the quality of fruit had no very big effect. The treatments of swelling agent increased GA content in early stages of fruit thus increased fruit-setting rate. The increasing of ABA content was good to the absorption of assimilation products in metabolic pool cell.
