Title: Inhibitory effect of Bacillus subtilis B10 on the diseases of postharvest strawberry
Abstract: Experiment was carried out with using Bacillus subtilis strain B10 as an antagonist for control of the gray mould (Botrytis cineria) disease of post-harvest strawberry. Fresh strawberries were used as material inoculated with different concentrations of the live liquid and suspension liquid of Bacillus subtilis strain B10 at different time and stored at different temperature for studying its effect of inhibitory capacity on the incidence of Boyrytis cineria; the inhibitory capacity of heat treatment and filter liquid were compared. Results showed that the cell culture mixture and washed cell suspension of B10 provided better control of Botrytis cinerea than heat-treated culture and culture filtrate. All treatments significantly inhibited the diseases both in vitro and in vivo compared with control. While at different temperatures of 25 ℃ and 15 ℃,higher storage temperature had lower infection rate and smaller lesion diameter. Considering the application time effect of B10 to Botrytis cinerea,earlier use of B10 had better bio-control efficacy. The inhibitory effect of washed cell suspension in controlling the natural disease was notable and the bio-control efficacy was significantly increased when applied concentration was higher. It was indicated that Bacillus subtilis can be used for control of the post-harvest diseases of strawberry fruit.
