Pathogenicity of Monilia spp. to hazel (Corylus)

Abstract

As a result of inoculating generative organs of hazel (fruitlets, unripe and ripe nuts) by the fungi Monilia coryli, M. fructigena and M. laxa it was found that each of the species could infect these organs but M. coryli appeared to be most pathogenic. Macroconidia of M. coryli originating from 14-day-old PDA cultures were found to be larger than those of M. fructigena and M. laxa. Hence a conclusion that Monilia coryli in the first place should be regarded as the principal cause of the brown rot of hazel.
