Effects of different rootstocks-grafting on plant growth,product quality and fruit weight of cucumber
Abstract： The cucumber variety ‘Jinchun 4’ was grafted on five different rootstocks of Cucurbita ficifolia, Cucubita moschata, Yellow seeded pumpkin, Squash and Loofah, and studied the effects of different rootstocks-grafting on plant growth, antioxidant enzyme activities, yeild and quality of cucumber. The results showed that the survival rate of Cucurbita ficifolia and Cucubita moschata were significantly decreased by 65.84% and 61.73 % as compared with self-grafted cucmber seedlings. However, other rootstocks had no significant effect on the survival rate. The grafted cucumber plants promoted plant growth and fruit yield of cucumber. Cucurbita ficifolia and Cucubita moschata as the rootstocks that showed higher values in plant height, dry weight and fresh weight, roots length, root number and root activity than those of self grafted cucumber seedlings. Cucubita moschata significantly increased the activities of CAT, POD, APX and SOD in cucumber leaves, while the activities of POD and APX in grafted of cucumber leaves was lower than that of self-grafted seedlings. Grey correlation analysis showed that the effect of Cucubita moschata grafting on the quality of cucumber was the largest, and other stocks reduced the quality of grafted cucumber. These results indicate that Cucubita moschata and Cucurbita ficifolia grafting could promote plant growth, increase the yield and improve fruit quality, which increasing the survival rate of grafting, as grafted cucumber suitable rootstock species.
