不同嫁接方法对温室黄瓜幼苗质量的影响

Effect of Different Grafting Methods on Greenhouse Cucumber Seedling Quality

以黑籽南瓜为砧木,"博耐33E"黄瓜为接穗,以自根苗为对照,研究比较了靠接、插接、断根嫁接、劈接4种嫁接方法处理对黄瓜幼苗生长特性的影响。结果表明:断根嫁接法幼苗成活率最高,插接法次之,劈接法成活率最低。嫁接苗在株高、茎粗、叶面积、根长、光合作用、保护酶活性等方面均显著优于自根苗;断根嫁接的各项指标均显著高于其它嫁接苗。嫁接可显著增加幼苗的保护酶含量,提高幼苗的光合速率,促进其生长。

Taking sunspot pumpkin as stock,with＇Bonai33E＇cucumber as the scion,the self root plant as the control,using the approach grafting,peg grafting,root cutting grafting,cleft grafting treatment of 4 kinds of grafting methods,effect of different grafting methods on growth characteristics of cucumber seedlings were studied. The resuhs showed that root cutting grafting seedling survival rate was the highest, followed by peg method, cleft grafting survival rate was the lowest. Grafted seedlings were significantly were better than those of self root seedling in plant height, stem diameter, leaf area,root length,photosynthesis, protective enzyme activity; each index of root cutting grafting were significantly higher than that of other grafted seedlings. Grafting could significantly increase the protective enzyme content of cucumber seedlings,increased the photosynthetic rate of seedlings and promote the growth.
