Effect of GA<sub>3</sub> and NAA on fruit quality and storage characteristics of fruit in sapota cv. Kalipatti

Abstract

The investigation was conducted at Department of Horticulture, College of Agriculture, Dapoli (M.S.) during 2017-19 to study the effect of GA3 and NAA on fruit quality and storage in sapota cv. Kalipatti. The application of GA3 150 ppm resulted in significantly maximum fruit length (6.16 cm),fruit diameter (5.81 cm),fruit weight (146.17 g),volume of fruit(138.77 cm³),specific gravity of fruit (1.05), pulp weight (138.00 g),pulp/seed ratio (99.28). The significantly maximum fruit TSS (25.10 0B),TSS/acidity ratio (192.60),reducing sugars (11.58%),non-reducing sugars(5.65%),total sugars (17.23%) and minimum titratable acidity of fruit(0.13%) were in fruits of GA3 150 ppm treatment. The GA3 150 ppm treatment resulted in significantly minimum PLW% on 2nd, 4th, 6th, 8th, and 10th day of storage of fruits (i.e. 3.11%, 6.29%, 9.98%, 11.55% and 28.43% respectively), shrivelling and/or spoilage percentage on 4th, 6th, 8th, and 10th day of storage of fruits (i.e. 0%, 5.33%, 9.33% and 18.67% respectively) and maximum shelf life (8.67 days).
