Abstract:

This paper reviewed the current research progress on cultivation effect and defense mechanisms involved in disease resistance of grafted watermelon at domestic and abroad, summarized the grafting methods and compared their advantages and disadvantages, introduced the cultivation effects of grafted watermelon, discussed the resistant mechanisms associated with grafting, including histology resistant, physiology and biochemistry resistant and grafting-induced resistant, meanwhile, the absence in current research and the research direction in the future work were also discussed. The authors thought that breeding of the excellent rootstock varieties and studies on resistant mechanism of grafted plant in molecular level should be strengthened, which would be of scientific significance in enriching disease-resistance theory of grafted plant.
