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.

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.File in questo prodotto:
