dc.description.abstractPresent investigation was carried out at research orchard of Division of Pomology and Post Harvest Technology,Udheywalla, SKUAST-Jammu during 2002 to ascertain the effect of girdling, thinning and GA<sub>3</sub> on fruit growth, yield, quality and shelf life of grapes cv. Perlette. Growth pattern of berry revealed that berry takes 52 days after fruit set (DAFS) or 69 days to mature under agro-climatic conditions of Jammu region. In general berry showed a double sigmoid nature of growth curve with verasion stage at 38 DAFS. All the treatments resulted in improved yield and quality. However, girdling + 40ppm GA<sub>3</sub> proved significantly most effective in increasing the berry size (1.88cmx 1.80cm), berry weight (3.05g), berry volume (2.73cc), bunch size (16.85cmx 14.33cm), bunch weight (495.73g) and average yield (8.87kg/vine) as compared to the control having berry size, berry weight, berry volume, bunch size, bunch weight and average yield as 1.69cmx 1.66cm, 2.23g, 2.06cc, 13.83cmx9.25cm, 292.34g and 5.32kg/vine respectively. The shot berries were significantly reduced by girdling+thinning+40 ppm GA<sub>3</sub> (10.08%) as compared to control (13.45%). The quality of the grapes was improved significantly by girdling + 40ppm GA<sub>3</sub> showing TSS (17.00%), TSS/Acid ratio (24.18), total sugars (15.04%) and reducing sugars (13.00%) as compared to control having TSS, TSS/acid ratio, total sugars and reducing sugars as 14.47%, 17.09, 14.02% and 11.86% respectively with an acidity of 0.689% with this treatment as compared to control (0.808%). At room temperature, significant reduction in physiological loss in weight was recorded under girdling + 40ppm GA<sub>3</sub> treatment (9,42%) as compared to control (22.31%) on third day of storage, but after wards the berries were sunken and shattered and were unmarketable under all the treatments including control. From this investigation it was concluded that trunk girdling +40ppm GA<sub>3</sub> was effective in increasing the yield, quality and shelf life of grapes cv. Perlette under agro-climatic conditions of Jammu region.en_US
