Vitis vinifera is the most famous edible species of grapes which is commercially propagated through hard wood cuttings. It belongs to Vitaceae family having sixty species. Hard woodcuttings take more time to sprout that is why success rate is low. To minimize this problem the present study was carried out to evaluate the effect of Auxinindole-3-butyric acid (IBA) concentrations (0 and 2000 mg/l) with three dipping times (0, 5 and 10 seconds) on ischolar_maining of grape cuttings of NARC Black, Thomson, Perlette, Flame seedless and King ruby varieties. The experiment was laid out according to Completely Randomized Design with three replicates. Result revealed that maximum leaf area (24.03), number of leaves per plant (9.04), ischolar_main length (16.721), number of ischolar_mains (37.68) and early ischolar_maining was obtained by Auxin (IBA) 2000 mg/l concentration with 10 second dipping duration. Auxin (IBA) 2000 mg/l concentration with5 second dipping time also increased the leaf area (22.57), number of leaves per plant (7.84), ischolar_main length (16.01), number of ischolar_mains (35.71)and early ischolar_maining as compared to control. In variety correlation in all parameter Thomson and NARC Black show best performance and low performance by Flame seedless. The results concluded that Auxin, IBA 2000mg/l with 10second dipping time is best to enhance growth, survival and ischolar_maining of grape cuttings.
