不同嫁接方式对番茄生长的影响

Effects of Different Grafting Methods on the Growth of Tomato

为了筛选出抗逆性好、适应性强、优质高产的番茄品种及繁殖方式,对金刚、乐美和仙鹤1号等3个西红柿品种作不同嫁接方式处理,在温室大棚内袋栽进行丰产性、稳定性、适应性、抗逆性等重要性状鉴定分析。结果表明,嫁接苗除对产量有显著影响外,在株高、茎粗、抗病性等方面较实生苗也有明显优势,不同嫁接方式在金刚和乐美两个品种脐腐病的发生率由高到低为实生、贴接、劈接,但对仙鹤1号优势不明显。综合分析得出适合安顺市引种的品种是乐美,适合安顺市番茄的繁殖方式是贴接。

In order to select tomato varieties with good stress resistance,strong adaptability,good quality and high yield and their propagation methods,three tomato varieties(Jingang,Lemei and Xianhe No.1),were treated with different grafting methods,the important characters of high yield,stability,adaptability and stress resistance were identified and analyzed in greenhouse.The results showed that the grafted seedlings had significant effects on yield,and had obvious advantages in plant height,stem diameter and disease resistance.The incidences of navel rot in Jingang and Lemei were from high to low,from seedling to pasting to splitting,but the superiority to Xianhe No.1 was not obvious.Comprehensive analysis showed that the suitable variety for introduction in Anshun was Lemei,and the suitable breeding method for tomato in Anshun was pasting.
