Effects of different rootstocks on the growth and development of root-cut-ting grafted watermelon seedlings
In order to screen suitable rootstock for root-cutting grafted watermelon,Zaojia(8424)watermelon was graft-ed on Jingxinzhen No.2 squash,Qinkangshuigua gourd and Yongshi wild watermelon.And the effects of different root-stocks on the growth and root development of root-cutting grafted watermelon seedlings were studied.The results showed that there was no significant difference among the transport capacity of the joint of root-cutting grafted watermelons grafted on 3 rootstocks.But the survival rate of the watermelon seedlings grafted on Jingxinzhen No.2 was the highest(89.9％).Compared with the self-rooted seedlings,the root cutting grafting method of 3 rootstocks improved the plant height,stem diameter,root to shoot ratio,strong seedling index and SPAD,and the Jingxinzhen No.2 rootstock treatment was the most prominent.Compared with Qinkangshuigua and Yongshi rootstock,watermelon seedlings root-cutting grated on Jingxin-zhen No.2 had better root growth and stronger root activity.In conclusion,Jingxinzhen No.2 is the best rootstock for wa-termelon by root-cutting method,which is suitable for popularizing in production.
