STUDIES ON ASCOCHYTA IMPERFECTA PECK. DIFFERENTIAL UTILIZATION OF NUTRIENTS BY ISOLATES FROM CANADIAN ALFALFA SEED
Isolates of Ascochyta imperfecta which had reacted differentially to 10 leguminous hosts were grown on a basic medium amended with various sugars, amino acids, and nitrogen sources. Significant differences in the yield of mycelium on the various media showed that these isolates responded specifically to different sugars and amino acids. Among the latter, cystine at 0.025% was inhibitory to all isolates. The significance of changes in the host on development of the fungus is discussed.
