Study on salt tolerance of six strains of endophytic fungi in Hordeum bogdanii
The purpose of this experiment was to clarify the effects of different salt concentrations on the colony morphology of endophytic fungi in Hordeum bogdanii.Six strains of endophytic fungi with different morphology were screened from Hordeum bogdanii from different regions of Xinjiang,and their growth on PDA medium with different salt concentrations of sodium chloride and sodium sulfate was studied.The results showed that the tested strains could grow in the medium with eight concentrations of sodium chloride(0,100,200,400,600,800,900,1 000 mmol/L)and five concentrations of sodium sulfate(0,100,200,400,600 mmol/L).Under the same salt concentration treatment,the salt tolerance of the strain in sodium chloride medium was higher than that in sodium sulfate medium.The endophytic fungus strain of strain A was extremely intolerant in sodium sulfate salt,and its hyphae were browned.Strain F had the worst growth and strain D had the best growth.Under 100 mmol/L sodium chloride treatment,the diameter of endophytic fungi colony of strain B was larger than that of the control group without salt.The study indicates that the results are helpful to understand systematically the salt tolerance of endophytic fungi in Hordeum bogdanii,and provide a reference for breeding plants for soil desertification control in saline-alkali areas.
