Effect of Soil pH and Soil type on the germinability of phialospores of Gliocladium virens Millers, Giddens and Foster

摘要

Phialospores of four isolates of Gliocladium virens viz., 15 GV_1, 26GV_1, 1AGV_2 and 1AGV 6 responded differentially to soil fungistasis in different soils of West Bengal according to the properties of soils explored. The pH of soil appeared to be the cardinal factor. The effect of soil fungistasis was more pronounced in alkaline soil followed by neutral soil but gradually decreased due to reduction of soil pH to acidic level. Fungistasis was more in unsterilized soil compared to sterilised one.
