Abstract

Shoots of several table and wine grape cultivars were cultured in vitro on a medium supplemented with polysaccharides obtained from a culture filtrate of Botryotinia fuckeliana through differential ethanolic precipitations. The general effects of polysaccharides resulted in leaf yellowness and in a reduction of fresh and dry weight. Differential response of assayed cultivars to polysaccharides seemed to be not related to their bunch susceptibility to grey mould under field conditions.
