Effect of Different Grafting Methods on Greenhouse Cucumber Seedling Quality

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 4kinds of grafting methods,effect of different grafting methods on growth characteristics of cucumber seedlings were studied.The results 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.
