摘要：
The muskmelon (Cucumis melon L.) production is facing a threat worldwide due to autotoxicity. In the laboratory and the greenhouse studies, we examined the Trichoderma sp's alleviation of toxicity of root exudates and autotoxic compounds secreted from the muskmelon plants. Eighteen Trichoderma strains were screened for their ability to grow in muskmelon root exudates. Of these T8 (T. harzianum) and T58 (T. viride) were further examined for their ability to degrade phenolics (ferulic, benzoic and cinnamic acids). These fungi degraded these phenolics and the extent of degradation followed the order: benzoic acid > ferulic acid > cinnamic acid. Pot studies indicated that these two strains also alleviated the autotoxicity caused by these three phenolic acids. These results indicate that the use of T. harzianum and T. viride is an efficient and promising approach to control the autotoxicity caused by continuous cropping of muskmelon.
