The Behavior of some Table Grapevine Cultivars in Relation to Phomopsis Viticola (Sacc.) Attack in Târnave Vineyard
Abstract
Phomopsis viticola (Sacc) causes excoriosis (Phomopsis cane and leaf spot), this results in high loses in grape production and in severe cases, death of the grapevine. The symptoms are as follows: the base of affected canes swells and blackens, and the scarred cortex may tear in longitudinal streaks, these canes are extremely fragile and easily break beneath their own load, other canes can completely dry. Data was collected and calculated (Phomopsis viticola AD, attack degree on leaves and canes) for the years 2021 and 2022, from the following cultivars: Kodryanka, Arkadia, Muscat New York, Moldova, Original, Muscat Poeloeske, and Muscat bleu as Vitis interspecific crosses cultivars, Victoria, Muscat Hamburg, Timpuriu de Cluj. Splendid and Transilvania as Vitis vinifera cultivars..Data comparison was done using the StatView software, ANOVA and ANCOVA test. In the present research work, it was demonstrated that in Tîrnave vineyard different table grapes cultivars behave differently to Phomopsis viticola (Sacc) attack.
