Effects of Salicylic Acid on the Growth of Three Mushroom Fungus Strains Hypha

[Objective]The research aimed to analyze the effects of salicylic acid(SA) on the growth of mushroom fungus strains hypha.[Method] The PDA medium added the salicylic acid for different concentrations were used to analyze the effects of salicylic acid on the growth of mushroom fungus strains hypha.[Result]The results showed that the different concentrations of SA had different stimulating effects on the growth of three mushroom fungus strains hypha(mushroom Xiawang,thuringiensis 6 and 9400).The low concentrations of SA had obviously stimulating effects,high concentrations had inhibiting effects.The mushroom Xiawang hypha grew best when SA concentration was 1.0×10-6 g/ml,thuringiensis 6 hypha grew best when SA concentration was 10.0×10-6 g/ml and 9400 hypha grew best when SA concentration was 1.0×10-6 g/ml.[Conclusion]AS is regarded as growth regulator in production of edible fungus was probable.
