As a special form of allelopathy,autotoxicity is common in cucurbits,and it is one of main factors inducing continuous cropping obstacles.Therefore,the autotoxicity research has both theoretical and practical significance on overcoming continuous cropping obstacles.In this review,commencing on the concept of autotoxicity,research results of autotoxicity in watermelon in recent years were summarized.The significance of researches on autotoxicity in watermelon,watermelon root exudate and its autotoxicity,and the autotoxicity of watermelon stubble and the mechanisms were explained.Meanwhile,some questions needed to be further studied.
As a special form of allelopathy, and it is one of major factors inducing continuous cropping obstacles. Before, the autotoxicity research has both theoretical and practical significance on over continuous cropping obstacles. In this review, commencing on the concept of autotoxicity, research results of autotoxicity in watermelon in recent years were summarized.The significance of researches on autotoxicity in watermelon, watermelon root exudate and its autotoxicity, and the autotoxicity of watermelon stubble and the mechanisms were explained.Meanwhile, some questions needed to be further studied.
