摘　　要：通过不同浓度的赤霉素(GA)和脱落酸(ABA)在嫁接西瓜坐果后对果实进行喷施处理,进行比较试验。结果表明:50mg/LGA、100mg/LGA、25mg/LABA和50mg/LABA的处理对嫁接西瓜果实内糖代谢相关酶活性的调节,均不同程度的提高了嫁接西瓜果实内可溶性总糖的含量,其中以50mg/LABA处理的效果最好。The effect of Gibberellin and Abscisic acid with different concentration on the grafted watermelon fruits was studied. The results showed that the soluble sugar content of grafted watermelon fruits on the treatment of 50 mg/L GA, 100 mg/L GA,25 mg/L ABA and 50 mg/L ABA was higher than the control. The soluble sugar content was changed by regulating the activity of Sucrose metabolism enzyme,the treatment of 50 mg/L ABA was the best.
