无籽西瓜嫁接效应研究

在湖北荆州采用靠接法和顶插接法对郑抗无籽5号、郑抗无籽6号、黑元帅、黑将军等4个无籽西瓜品种进行了嫁接育苗与栽培效应研究。结果表明:采用嫁接栽培的西瓜显著降低了枯萎病的发病率、病情指数及病死株率,产量显著提高;采用靠接法的嫁接苗成活率和单果重显著高于顶插接法;采用顶插接果实中心可溶性固形物含量有提高的趋势;嫁接西瓜口感与自根西瓜无明显差异。郑抗无籽5号、6号的综合表现较优。

Evaluation of grafting method and grafted seedless watermelon

Four seedless watermelon cultivars Zhengkang Wuzi No. 5,Zhengkang Wuzi No. 6,Heiyuanshuai and Heijiangjun,were grafted to Lagenaria rootstock by using top-insertion and side-grafting methods to evaluate the quality of grafted seedling and their performance in the field. The results showed that grafting reduced Fusarium wilt incidence,severi-ty and mortality of plants due to disease. Grafted plants produced significantly higher yield of seedless watermelon. Side-grafting had better success rate and the grafted plants produced bigger fruit than those of top-insertion grafting. However,the fruit from top-insertion grafting had higher soluble solids. Grafted plants produced seedless fruit with similar flavor of those of non-grafted plants. Zhengkang Wuzi No. 5 and Zhengkang Wuzi No. 6 had better performance in the tests.
