NaCl and Phaeomoniella chlamydospora affect differently starch and sucrose metabolism in grapevines [PDF]

Acta Scientiarum. Agronomy, 2013
Vineyards production is often affected by diseases as esca and Petri disease and by excess of salt. Phaeomoniella chlamydospora is one of the pathogenic fungi associated to esca disease, but its interaction with the plant under excess of salt remains unknown. Under controlled in vitro conditions, Vitis vinifera L.
