Abstract
The carbon and nitrogen nutrition ofClaviceps microcephala, isolated from the ear heads ofPennisetum typhoides, was studied at 24°C for 20 days at pH 6·0. Out of forty-one carbon compounds tested, the pathogen showed excellent growth on dextrose, sucrose, pectin and methyl alcohol; good on mannose, fructose and maltose; fair on galactose, cocount oil and isopropyl alcohol; and poor or no growth on rest of the carbon compounds. Out of thirty-three nitrogenous compounds tested, the pathogen showed excellent growth on casein hydrolysate, yeast extract, asparagine, peptone, proline, glutamic acid and aspartic acid; good on ammonium nitrate and ammonium oxalate; fair on ammonium chloride, ammonium sulphate, arginine mono HCl and ammonium phosphate; and poor or no growth on rest of the nitrogen compounds. In general, compounds which supported best mycelial growth ofC. microcephala yielded its excellent sporulation andvice versa.
