绿菇[Russula virescens(Schaeff.)Fr.]对灰霉菌(Bortrytis cinerea)的拮抗作用研究

Antagonism Effect of Russula virescens (Schaeff.) Fr.on Bortrytis cinerea

本文首次研究了绿菇[Russula virescens(Schaeff.)Fr.]对5种灰霉菌的拮抗作用。结果表明,绿菇对灰霉菌的拮抗作用主要表现为菌丝体重寄生和代谢产物生长抑制作用,对峙生长抑制率介于46.9%～52.3%,重寄生现象明显;PDB培养基培养绿菇获得的发酵液生长抑制作用最强,对辣椒灰霉菌生长抑制率最高,为61.59%;发酵液热稳定性良好;绿菇菌丝提取液对供试灰霉菌无生长抑制作用。

The antagonism of the fungi Russula virescens（Schaeff. ）Fr. to five strains of Bortrytis cinerea was studied. The result showed the antagonism of Russula virescens（ Schaeff. ） Fr. to Bortrytis cinerea mainly included hyperparasitic mycelium and the inhibition effect of metabolite. The confrontation ratio ranged from 46.9 % to 52.3 % and mycelium parasitism was visible. The zymotic fluid after cultured Russu/a vlreseens（Schaeff. ）Fr from PDB had the strongest effect on Borttytis cinerea and the growth inhibition rate of the zymotic fluid to Butrytis cinerea on pepper was the highest , arrived 61.59 %. Thermal stability of the zymotic fluid was good. Mycelium extract had no effect on Bortrytis cinerea.
