Effect of Grafting Methods on Grafting Working Efficiency,Seedlings Growth and Fruit Quality of Watermelon

The hole insertion and root pruning hole insertion grafting methods were often used in the production of grafted seedling in industrial scale,the present study investigated the effects of the two grafting methods on grafting working efficiency,seedlings growth and fruit quality of watermelon.The results showed that the grafting speed,survival rate and grafting working efficiency of root pruning hole insertion method was significantly higher than those of hole insertion method.Compared with hole insertion grafted watermelon seedlings,root pruning hole insertion grafted seedlings have higher seedling quality as well as higher root/shoot dry weight ratio and root activity.However,there were no significant effect on plant growth and fruit quality of watermelon between the two grafting methods.Thus,the root pruning hole insertion grafting was an effective method for the production of grafted watermelon seedlings in industrial scale.
