不同西瓜嫁接砧木的筛选与研究

Screening of Different Rootstocks for Watermelon Grafting

以西瓜品种‘早佳84-24’为对照和接穗,分别与6个不同类型的砧木进行嫁接,探讨不同砧木对西瓜生理性状、果实品质和抗病性等的影响,从中筛选出适合‘早佳84-24’嫁接砧木的优良品种。试验结果表明,在6个砧木品种中,‘刚强’‘Nf1’与西瓜品种‘早佳84-24’嫁接后,长势旺盛、产量高、抗病性强,可作为三亚地区西瓜嫁接栽培的砧木品种。

The watermelon variety ＇Zaojia 84-24＇ was used as the control variety and grafted with six different types of rootstocks, and the effects of different stocks on physiological characters, fruit quality and disease resistance of watermelon were discussed to select good root stock varieties which are suitable for grafting with ＇Zaojia 84-24＇ in Sanya. The results showed that watermelon variety ＇Zaojia 84-24＇ grafted with the rootstocks ＇Gangqiang＇ or ＇NF1＇ out of the 7 rootstocks grew vigorously and yielded high with higher tolerance to diseases. These two rootstocks can hence be used as rootstocks for watermelon in Sanya.
