Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 4
Abstract
To know the response of apricot to plant growth regulators, a field experiment was conducted at the Fruit Orchard, Department of Fruit Science. V. C. S. G Uttarakhand University of Horticulture and Forestry, Bharsar, Uttarakhand during 2014-2015. The experiment was laid out in Randomized Complete Block Design (RCBD) comprised of nine treatments and three replications having various combinations of growth regulators (GA3 and NAA) applied at full bloom stage. Among all the treatments applied,‘T5’{GA3 10ppm + NAA 10 ppm} performed best with highest fruit set (60.59%), fruit yield (26.33 kg), fruit size (2.14 cm × 2.61 cm length × diameter), fruit weight (22.33 g.), fruit volume (32.05 cm3/fruit), fruit firmness (1.26 kg/cm2), highest total soluble solids (21.00 0 Brix), titrable acidity (0.67%), ascorbic acid (13.45 mg/100 gram), total phenol (0.07 mg/100 gram), total sugar (21.22%), reducing sugar (4.27%) and non reducing sugar (16.11%).
