摘要

Agrobacterium vitis is a common pathogen in vineyards Worldwide and results in serious yield and quality losses. This study was conducted With Nar- ince (V itis vimfera L.) grape cultivar for two years. Effects of different A. Vitis-induced tumor cover ra- tios over the crown (healthy, 20, 40, 60, 80 and 100% tumor covers) on grapevine development, yield and quality were investigated. Experiments were con- ducted in randomized blocks design with 6 replica- tions and resultant data were subj ected to variance analysis (AN OVA). Present ?ndings revealed about 42% recession in development of A.Vitis-infected grapevines, 63% recession in yield, 29% recession in number of clusters, 47% recession in cluster Weight, 21% recession in berry Weight and 20% recession in ripening index values of Narince grapes. Titretable acidity of infected grapevines increased by 19%. Ripening retarded with increasing tumor cover ratios over the crown.
