| 摘 要： | 为探究黄瓜中是否存在嫁接诱导农艺性状变异现象,通过选用主要农艺性状存在明显差异的多份黄瓜高代自交系进行相互砧穗嫁接,对不同嫁接处理接穗G1代的主要农艺性状进行了对比分析。结果表明,嫁接处理2024/3297与自根嫁接处理2024/2024相比,接穗G1代雌花数量、雌花节位、F基因表达量显著减少;对接穗G1代果实长度进行对比分析,发现砧穗嫁接与对应自根嫁接处理相比果实长度发生变化。然而,对接穗G1代果实横径和果皮颜色进行对比分析,砧穗嫁接与自根嫁接处理之间不存在显著差异。黄瓜中存在嫁接诱导接穗后代部分农艺性状出现变化的现象。

| Abstract: | To explore whether there were graft-induced effects on genetic variation of agronomic traits,a series of reciprocal grafting treatments were set up among cucumber high-generation inbred lines having different agronomic traits.Comparative analyses on main agronomic traits were conducted between G1 of different grafting treatments.The results indicated that:Compared with self-rooted grafting treatment 2024/2024,G1 of grafting treatment 2024/3297 had significant reductions in female-flower number,female-flower node and F gene expression.Changes were detected between grafting treatments and self-rooted treatments when making comparative analyses of fruit length.However,there was no significant difference of fruit diameter and fruit color observed.Our results suggested that graft-induced effects could lead to changes of some agronomic traits of cucumber. |
