Abstract

|
The effects of amino acids on mycerial growth and sporulation of the decreased and increased pathogenicity variants of potato dry rot Fusarium roseum `Sambucinum´ were as following. The increased pathogenicity variants Ic52 and Ic116 showed the trend of greater mycerial growth, marking up to 67㎎ on leucine, than the decreased pathogenicity variants Dc14 and Dc91, and produced markedly low conidia below 25 × 10⁴/㎖ or no sporulation. On methionine all the variants and the wild type showed the lowest growth recording 14㎎ to 20㎎ with no sporulation. Cystine similarly as glysine supported the poor growth 30㎎ to 19㎎ of the variants Dc14 and Dc91, respectively, and did not support the sporulation. The former amino acid like asparagine supported the growth of the variants Ic52 and Ic116 marking 47㎎ and 36㎎, respectively. On all the eleven amino acids the variant Dc14 showed the trend of more mycerial growth and sporulation than the variant Dc91 which marked the exceptionally high sporulation 195 × 10⁴/㎖ on glutamic acid.
