IMPACT OF AUXIN AND NUMBER OF BUDS LEFT IN CUTTINGS FOR THE ROOTING AND GROWTH OF GRAPE TRANSPLANTS OF CV. HALWANI AND KAMALI
2025
A. Hussein, S. | A. Zaili, Sh.
This study investigated the effect of treating cuttings with auxin indole butyric acid (IBA) at three concentrations of 0, 500, and 1000 mg L-1 by rapid immersion for 10 seconds. The number of buds on the cuttings were determined at three levels (3, 5 and 7 bud cutting-1) on the rooting and vegetative growth of grape transplants of Halwani and Kamali cultivars. Each cultivar had 135 cuttings for a total of 270 cuttings for both cultivars. Dipping the cutting bases of the cultivars with IBA in 1000 mg L-1 concentration resulted in significant superiority in the percentage of rooted cuttings, average root length, root dry weight, vegetative system dry weight, average transplant height, diameter, number of leaves, leaf area and chlorophyll content. The auxin treatment did not affect the leaves nitrogen content for both cultivars. The 3- and 5-buds cutting-1 of the Halwani grape cultivar had a significant effect on the rooted cuttings, reaching 95.00 and 95.56%, respectively, while the 5-bud cuttings of the Kamali cultivar significantly increased the number of rooted cuttings and total nitrogen in the leaves at 99.33 and 2.53%, respectively. Cuttings of 5 buds from both cultivars had a significant effect on their average root length, dry weight of the root and vegetative system, average transplant height, number of leaves, leaf area and leaf content of chlorophyll. However, average transplant diameters for both cultivars were not affected by the number of buds left on the cuttings
