The Perennial ryegrass, Tall fescue and Red fescue have the largest seed germination rate under the 8 grades NaCl concentration stress. With the concentration increasing, the seed germination of turfgrass sharply decreased. Most of the turfgrass seeds couldn germinate under the NaC1 stress which concentration was above 0.1%, besides the Zoysia, Alkali grass and Creeping bentgrass got a good germination rate.

The results showed that BS-LX04 had strong antagonistic activity on the mycelia growth and conidia germination. The hyphae were suppressed by BS-LX04 and presented malformation. The conidia germination was inhibited, with an inhibition percentage of 73.22% when examined at 24 h after test. The germination was delayed by BS-LX04 and the germ tube and hyphae also presented malformation though some of the spores germinated and formed hypha.
