地肤内生细菌对番茄灰霉病菌的拮抗作用
Antagonism of Endophyte Bacteria from Kochia scoparia on Botrytis cinerea
摘要
Abstract
The aim of the study is to screen anti-microorganism endophytic bacteria for plant disease control. Five strains from the Kochia scoparia exhibited extensive antagonistic activities against Botrytiscinerea. D-29 strain showed strong antagonistic activity against Botrytis cinerea on tomato in vitro. The fermentation solution, suspension of bacteria and sterile filtrate could reduce the expension of leisons on red tomato in vitro and inhibitory rate reached 64.61%, 61. 50% and 44. 10% respectively. Fermentation solution could reduce the expension of leisons on green tomato in vitro and inhibitory rate reached 100% and 67. 11% in the 4d and 6d. The results of observation under microscope illustrated that D-29 could make cell material leaked and the deformity of top mycelium and spores infarction. 100% D-29 sterile filtrate had the most significant inhibitory effect anginst spore germination of Botrytis cinerea and its inhibiting rate reached 80%.关键词
