根际内生菌对猕猴桃溃疡病生防作用研究初探
Preliminary exploration of biocontrol effect of rhizsphere endophyte on kiwi fruit canker
摘要
Abstract
The in-vessel antagonism activity test was conducted toward the 9 rhizosphere endophytes gained by primary stage's separation and purification,and the JDG6,JDG16 and JDG23 bacterial strains which possessed significant inhibitory effect toward the pathogenic bacterium of kiwifruit bacterial canker were screened.The mean diameters of their inhibition zones were 13.0 mm,14.5 mm,and 12.5 mm.The JDG16 had the best inhibitory effect.The pot experiment was conducted toward the 3 bacterial strains.The results showed that when the dilution of fermentation filtrate was 100,all JDG6,JDG16 and JDG23 had strong antagonistic activity and could decrease the invasion rate of the pathogenic bacterium of kiwifruit bacterial canker,restrain the extension of bacteria in the plant and decrease the damage of bacteria toward the plant.Thus,the results provided some reference for the research on biocontrol strain of kiwifruit bacterial canker.关键词
