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 the black-seed pumpkin as the rootstock and the “Bo-resistant 33E” as the scion and the self-rooted seedling as the control, the effects of four grafting methods on the growth characteristics of cucumber seedlings were compared and studied. . The results showed that the survival rate of seedling grafted by root-grafting was the highest, followed by plugging method, and the survival rate of cleavage method was the lowest. Grafted seedlings were significantly superior to self-rooted shoots in plant height, stem diameter, leaf area, root length, photosynthesis, and protective enzyme activity. The indexes of root-grafting were significantly higher than those of other grafted seedlings. Grafting can significantly increase the protective enzyme content of seedlings, improve photosynthetic rate of seedlings and promote their growth.
