Abstract
Grapes Vitis vinifera is the most famous edible species of grapes which belongs to the family vitaceae is commercially propagated through hard wood cuttings. Hard woodcuttings take more time to sprout that is why success rate is low. To minimize this problem the present study was carried out at Department of Horticulture, Faculty of Agriculture, Annamalai University to evaluate the effect of Indole-3-butyric acid on rooting of grape cuttings with ten treatments at different concentrations namely T1 – IBA 500 ppm, T2 – IBA 1000 ppm, T3 – IBA 1500 ppm, T4 – 2000 ppm, T5 – 2500 ppm, T6– 3000 ppm, T7 – 3500 ppm, T8 – 4000 ppm, T9 – 4500 ppm, T10 – Control. The obtained results revealed that IBA has significant effect on rooting of grape cuttings. Treatment T4 - 2000 ppm of IBA for 5 minutes showed maximum results for all root and shoot characters like days required for sprouting, length of roots, number of leaves per shoot, number of roots per cutting, shoot length, rooting percentage and survival percentage with 16.52 days, 6.85 cm, 3.69, 13.69, 15.68 cm, 88.36 % and 94.30 % respectively followed by treatment T6 - 3000 ppm of IBA for 5 minutes with 16.16 days, 6.57, 3.53, 12.78, 15.08 cm, 83.51 % and 91.99 % respectively when compared with control. The results concluded that IBA 2000 ppm with 5 minute dipping time is best to enhance growth, survival and rooting of grape cuttings.
