Effect of Synthetic and Natural Growth Hormones on Morphology of Rooting in Grape (Vitis vinifera L.) Cuttings Cultivar Punjab Macs Purple

Abstract

In this research, effect of the different natural (Cinnamon powder, apple cider, honey, Aloe vera) and synthetic hormones like growth regulators (IAA, IBA, GA₃) were tested along with control treatment on the rooting in hardwood cuttings of grape (Vitis vinifera L.), cultivar Punjab Macs Purple. The hardwood cuttings were dipped in solution of IBA 2000ppm for 2 minutes and then planted in the main field. The observations were recorded at an interval of thirty, sixty and ninety days after planting. The treatment T_9, applied with IBA 2000 ppm was found with highest number of roots (52.66), number of shoots (52.66) root girth (7.83mm), shoot length (30.73cm), chlorophyll content (30.60nm) and survival percentage (73.33%) after 90 days. Treatment of IBA 2000 ppm was found more effective in rooting and shoot growth of hardwood grapes cutting. Natural hormones like Aloe vera was found as promising alternative rooting hormone for the propagation of grape cuttings.
