Response of Some Important Olive Cultivars against Wilt Disease Caused by Verticillium dahliae Kleb.

This study was carried out to determine some olive varieties' response Verticillium dahliae Kleb. widely grown in Kahramanmaraş, Turkey. In an initial the optimal development of V. isolate at different temperatures, exhibited growth 20°C. The optimum determined on four mediums. colony rate not significant all tested media. detached leaves seven varieties were assayed PDA if attracted leaf exudates leached from vitro. Detached Memecik (26.90 mm) and Kalamata (26.83 did affect diameter compared Control groups 8th day. Domat variety (31.30 resulted most PDA. A cross-section stem (0.5 cm) removed upper parts inoculation point by measuring 1, 2 3cm planted medium disease severity. displayed lowest severity with a 0.44, followed Manzanilla 0.66 other (1, 3 cm point). These results indicated that tolerant section experiments treatments. However, susceptible according
