摘要
水稻污点病菌(Cladosporium cladosporioides)在改良Fries 3号培养液上最易产生毒素,且以25 ℃,振荡培养20 d产毒量最高。该毒素对水稻幼苗有明显致病作用。毒素滤液及粗提物的毒性均随浓度的升高而增强。且粗提物的毒性明显高于同一浓度滤液毒性。
The experimental results indicated that:the max. production of cladosporium herbarum pathotoxin had been got in changed Fries 3 Liquid medium for 20 days under 25 ℃ and oscillating. The pathotoxin had the significant pathology effect on rice seedlings. The higher the content was, the bigger the toxin of culture filtrate and crude purified was, meanwhile the toxin of crude purified was bigger than that of culture filtrate under the same content condition.
