作者（2019）在《Effects of Different Rootstocks on Plant Growth and Fruit Quality of Watermelon》一文中研究指出：[Objectives] This study was conducted to explore the effects of different rootstocks on plant growth and fruit quality of watermelon. [Methods] The scions of two different watermelon varieties Qianmei No. 1,which has yellow flesh,and Qianli No. 1,which has red flesh,were grafted onto six different rootstocks of Lagenaria and Citrullus. Then,the seedling survival rate,growth potential and fruit quality in different rootstock-scion combinations were investigated.[Results]Rootstock type showed an extremely significant correlation with the survival rate of grafted watermelon plants. The watermelons grafted onto Lagenaria rootstocks had higher survival rate and better fruit quality than those onto Cucurbita rootstocks. Among them,Jingxinzhenguan was more suitable for red-fleshed watermelon variety,and bottle gourd rootstock was more suitable for yellow-fleshed watermelon variety. There were significant correlations between rootstock type and the number of leaves,the number of branches and the length of main vine of grafted plants. The number of leaves per seedling of all grafted plants was higher than that of non-grafted plants. There were no significant differences in sugar content at the center part of flesh and total soluble sugar content of fruit between the grafted and non-grafted watermelons. In addition,the interaction between rootstock type and watermelon variety had no significant effect on vegetative growth and fruit quality of grafted watermelon. [Conclusions] This study provides a theoretical basis for the grafting of watermelon.
