扬州大学园艺与植物保护学院近期利用小麦纹枯病菌毒素,研究植物病原菌毒素对寄主植物的致病害作用。试验结果表明:该毒素在不同浓度下对小麦有2种截然不同的作用结果。高浓度毒素能在叶鞘上造成类似于病斑的症状;抑制幼根生长,最高抑制率可达97.9%;损伤细胞膜, Yangzhou University College of Horticulture and Plant Protection recently using wheat sheath blight toxin to study the pathogenic role of plant pathogenic toxins on host plants. The test results show that the toxin has two distinctly different effects on wheat at different concentrations. High concentrations of toxins in the sheath caused similar symptoms of lesion; inhibition of root growth, the highest inhibition rate of up to 97.9%; damage the cell membrane,
