Growth Potential of Bipolaris oryzae under Temperature, Storage and Nutrient Conditions

This study evaluates the growth potential of Bipolaris oryzae under varying temperature conditions, nutrient composition, and storage duration. Experiments were conducted to assess the development of fungal colonies across a temperature gradient from 10°C to 40°C, with optimal growth observed between 20°C and 30°C. Additionally, the fungus was cultured on various artificial media, with Potato Glucose Agar (PGA) and Malt Extract Agar (MEA) proving most favorable for growth and sporulation. The study also investigated the effect of seed storage on fungal persistence, showing consistent infection rates over a nine-month period. These results highlight the crucial role of temperature, nutrient availability, and storage conditions in managing B. oryzae in agriculture. The findings reinforce the importance of avoiding infected fields for seed production and implementing proper storage practices to minimize fungal spread.
