The effect of volatile compounds on the plants and pathogen will be examined. The kinds of volatile compounds will be analyzed by gas chromatography. The candidates will be tested for their effects on the plant growth and plant responses to the pathogen attack. Afterwards, the volatile compound candidates will be examined for the effects on fungal growth to see if they have same effects as the biocontrol strain and its volatile compounds released. This study will facilitate the application development of bacterial strain used.生物防治菌株植物促生作用抑病作用活性成份biocontrol strainplant growth promotiondisease suppressionactive compounds
