Influence of media, pH and temperature on growth and sclerotial production of Rhizoctonia solani kühn causing aerial blight of soybean
2009
Ray, Anjana | Pradeep Kumar
Five different media tested, among them, Czapek's Dox Agar supported best mycelial growth (75.13 mm) and sclerotia production of the fungus followed by Potato Dextrose Agar, Asthana and Hawker's medium, Richard's medium and Corn meal agar media. The colony diameter and sclerotia production of R. solani was maximum at 300C on Czapek's Dox agar medium followed by 35, 25, 20 and 150C. Maximum mycelial dry weight (379.67 mg) of the test fungus was recorded at pH 7.0 while minimum dry weight (115.21 mg) at pH 3.0.
