| 摘 要： | 研究了4种大豆根腐主要病原菌毒素毒性大小，毒素对大豆幼根细胞膜透性的影响，不同病原菌毒素与毒素互作以及毒素与病原菌共同作用对大豆根部发病的影响。结果表明：4种病原菌中，尖镰孢菌毒素毒性最强，并随着浓度增加，对大豆根细胞膜透性的影响增强。四种毒素互作对大豆幼根毒害作用的正交试验得出，尖镰孢菌毒素在其过程中起着重要的作用。病原菌与毒素共同接种时，尖镰孢菌毒素处理的发病加重，病情指数比不接毒素处理的上升10%左右。

| Abstract: | The effects of toxins of four main pathogens of soybean root rot on the permeability of cell membrane, and the effects of the interactions of different toxins, simultaneous inoculation of pathogens and toxins on causing soybean root rot were studied in this paper. The toxicity analysis indicated that the most poisonous is Fusarium oxysporum toxin of them. And the membrane permeability increased while the concentration of it also increased. Orthogonal experiment of four toxins interaction effect on radicle c... |
