不同地区采集的尖孢镰刀粗毒素滤液对亚麻种子萌发的抑制率不同;利用尖孢镰刀菌粗毒素滤液对不同品种的亚麻种子进行处理,研究结果表明粗毒素滤液对亚麻种子萌发有明显的抑制作用,发芽率明显降低,胚根的长度明显比对照组短,对胚根生长的抑制率为21.2%-42.4%,且处理后的亚麻种子很难成苗,对其受害幼苗进行尖孢镰刀菌分离结果表明,从根茎2-3cm处均可分离到尖孢镰刀菌。 The different concentrations of Fusarium oxysporum extract collected from different areas had different inhibition rates on the seed germination of flaxseed. The different kinds of flaxseed were treated with Fusarium oxysporum crude toxin filtrate. The results showed that the crude toxin filtrate inhibited the seed germination significantly The germination rate was significantly reduced, the radicle length was significantly shorter than the control group, the inhibitory rate of radicle growth was 21.2% -42.4%, and the treated flax seed is difficult to become a seedling, the victim seedlings were sickle sickle Isolation of bacteria showed that Fusarium oxysporum could be isolated from roots 2-3 cm.
