Abstract：In order to explore the effects of different rootstocks on the growth,resistance to Fusarium wilt and physiologi-cal indexes of small fruit watermelons after grafting,this study used small fruit watermelon Jucheng Huiling as the scion,and self-rooted grafted seedlings as the control.Five pumpkin rootstocks and four gourd rootstocks were selected as exper-imental subjectss.The results showed that the highest graft survival rate was observed in the grafted seedlings of Jingxin Zhen No.4(98.3％).The best performance in promoting scion growth and increasing yield was observed in the grafted seedlings of Yongzhen No.5,which resulted in a 35.9％yield increase compared to the control.In terms of quality,the highest soluble solid content in the center was found in the grafted seedlings of Jingxinzhen No.4,reaching 13.2％.After inoculation with watermelon Fusarium wilt,the grafted seedlings of Yongzhen No.5 showed the strongest resistance,with a disease incidence of 21.25％,a disease index of 6.67,and a disease prevention effect of 91.47％,reaching a high resistance level.The POD activity in the leaves of the grafted seedlings of Yongzhen No.5 was significantly higher than that the control,while the MDA content was significantly lower than the control.In conclusion,the pumpkin rootstock Jingxinzhen No.4 and gourd rootstock Yongzhen No.5 showed the best results and are suitable for promotion and applica-tion in production.
