Abstract
Ammonia applied as NH4Cl in a Tris–HCl buffered solution (pH 7.5 or 8.5) reduced germination of conidia of Fusarium solani f. sp. phaseoli at 250 mM NH4Cl (pH 7.5) or 5 mM NH4Cl (pH 8.5) and of conidia of Cochliobolus victoriae at 5, 50, or 250 mM NH4Cl (pH 7.5) or 5 mM NH4Cl (pH 8.5). Under these conditions the rate of 14C release from conidia of these fungi and of Botrytis cinerea, grown on a medium with [14C]glucose, did not increase. It is concluded that no enhanced release of carbon compounds from conidia is involved in ammonia-induced mycostasis.Keywords
