The Vitamin, Carbon And Nitrogen Nutrition Of Pircularia Oryzae Cav. Part II
No full textVitamin requirement for growth and sporulation of a certain isolates of Piricularia oryzae Cay. were determined. Of the vitamins studied, only biotin and thiamine were essential to the growth of the fungus. Other vitamins were found ineffective. The depend-ency of the fungus on biotin was greater than on thiamine. All isolates tested required exogenous biotin for mycelial growth. It was found that a majority of the isolates had a partial requirement for thiamine. No isolates exhibited an absolute requirement for thiamine. Both biotin and thiamine were absolutely essential for the sporulation of P. oryzae. No conidia were produced by any isolate in either biotin or thiamine free media. In the absence of thiamine, several isolates of the fungus were able to make fairly abundant mycelial growth, but failed to produce spores. The minimum concentration of biotin for the optimum mycelial growth of the fungal isolates was 0.5 ug/1, and of thiamine, 0.02 mg/i. Below these concentrations, the growth of the fungus was drastically reduced. No correlation was observed between pathogenicity and vitamin requirement of the fungus
