Growth of Phaeoisariopsis personata was measured in different temperatures of 10, 15, 20, 25, 30 and 350C on peanut leaf oatmeal agar medium and maximum growth was observed in 250C. At very high and low temperature conditions like 10, 15 and 350C growth was very slow. At 200C growth was slow as compared to 250C and 300C where growth fast was observed. In the liquid medium, potato dextrose broth showed significant difference in growth and dry weight accumulation at different temperatures. Highest dry weight was accumulated at 250C (1025mg) followed by 300C (969mg) and 200C (635mg), whereas 150C accumulated less dry weight (312mg) followed by 350C (292mg) and 100C (273mg). The mycelial growth decreased with decreasing and increasing temperatures beyond the optimum temperature range of 25-300C. So by visual observation at 20 days after inoculation on peanut leaf oatmeal agar and dry weight of mycelial mat was measured in case of liquid media to see the effect of different temperatures on growth of the pathogen.

Abstract


Growth of Phaeoisariopsis personata was measured in different temperatures of 10, 15, 20, 25, 30 and 350C on peanut leaf oatmeal agar medium and maximum growth was observed in 250C. At very high and low temperature conditions like 10, 15 and 350C growth was very slow. At 200C growth was slow as compared to 250C and 300C where growth fast was observed. In the liquid medium, potato dextrose broth showed significant difference in growth and dry weight accumulation at different temperatures. Highest dry weight was accumulated at 250C (1025mg) followed by 300C (969mg) and 200C (635mg), whereas 150C accumulated less dry weight (312mg) followed by 350C (292mg) and 100C (273mg). The mycelial growth decreased with decreasing and increasing temperatures beyond the optimum temperature range of 25-300C. So by visual observation at 20 days after inoculation on peanut leaf oatmeal agar and dry weight of mycelial mat was measured in case of liquid media to see the effect of different temperatures on growth of the pathogen.
