黄瓜嫁接防治枯萎病和疫病技术的研究

Study on the control of fusarium wilt and phytophthora blight in cucumber by grafting

研究津研4号黄瓜和4种瓜类砧木嫁接的亲和性,及嫁接黄瓜对黄瓜疫病和黄瓜枯萎病的抗性,测定嫁接黄瓜的长势、产量及品质。结果表明,圆瓠瓜、黑籽南瓜和冬瓜均适作黄瓜的嫁接砧木。其嫁接苗的嫁接成活率在98%以上,在接种黄瓜疫病和黄瓜枯萎病病菌的条件下,成活率比非嫁接苗高20%,产量比非嫁接苗增加100%以上,且生长势旺,对果实品质无影响。其中,又以圆瓠瓜最适作黄瓜的嫁接砧木。

Survival, growth, yield and quality of cucumber grafted were studied,and the resistances to fusarium wilt and phytophthora blight were evaluated. The results indicated that Lagenaria siceraria, Cucurbita moschata and Benincasa hispida were suitable to be used as tree stocks during cucumber grafting, with more than 98% of survival for cucumber seedlings grafted. When inoculated with Phytophthora drechsliri and Fusarium oxysporum,more cucumber seedlings grafted survived than those without grafting by 20%, and also a higher yield was harvested by more than 100%. Besides, the plants of cucumber grafted grew vigorously, and no effects were found on the quality of fruits.Lagenaria siceraria was the best tree stock for grafting of cucumber.
