Induction of rooting in grape (ARI 516)

Basal cuttings having more than 8 mm diameter showed better rooting than apical sections of the shoots. Cuttings treated with low temperature (4°C) for 24 hrs before planting initially sprouted well, up to 45 days, but could not survive until 90 days. Cuttings from middle portion having the size of 5±1 cm survived better for IBA treatment at 90 days. NAA did not help rooting. Hormones when externally applied did not show any role in promoting roots.
