[目的]研究果砧一号嫁接番茄对根结线虫的抗性。[方法]采用果砧一号、托鲁巴姆嫁接番茄幼苗,并与自根苗相对比,探讨三种处理对根结线虫的抗性。[结果]采用果砧一号嫁接的番茄植株,与其它两个处理亩产量平均增长1 162.45和2 116.91 kg;株高比两对照分别增加10.55和14.54 cm,差异显著;茎粗比两对照分别提高0.56和1.13 cm,差异显著;根结线虫病情指数三处理分别为0.55、10.42和45.31,在0.05%水平上差异极显著。[结论]该研究可为番茄嫁接防治根结线虫提供理论依据。
[Objective] The research aimed to study the resistance of rootstock No. 1 to root-knot nematode. [Method] The seedlings of tomato were grafted on the fruit of Rugushanglou and Torumbam, and compared with the self-rooted seedling, the resistance of the three treatments to root-knot nematode was discussed. [Result] The results showed that the average yield per mu of two grafted tomato plants increased by 1 162.45 and 2 116.91 kg compared with the other two treatments, respectively. The height-to-weight ratio increased by 10.55 and 14.54 cm respectively, Increased 0.56 and 1.13 cm, the difference was significant. The root knot nematode disease index three treatments were 0.55, 10.42 and 45.31, respectively, with a significant difference at 0.05% level. [Conclusion] The study could provide theoretical basis for tomato grafting to control root knot nematode.
