Abstract:
The experiment was carried out at Fruit nursery, Department of the Horticulture, Marallia (Miran Sahib) Jammu during 2018-19. Different bagging materials (brown paper bag, newspaper bag, muslin cloth bag, butter paper bag, laminated brown paper bag, white polypropylene bag. pink polypropylene bag) were used in combination with different time of bagging (20 days, 30 days and 40 days after fruit set). Results shows that panicles bagged with pink polypropylene bag 40 days after fruit set showed least fruit cracking (14.02%) and pericarp sunburn (18.85%) however this treatment also resulted in maximum fruit retention per panicle (54.92%) and fruit yield (78.81 kg/tree). Among the various physical parameters studied, fruit weight (21.64 g), fruit length (4.21cm), fruit breadth (3.96 cm) fruit volume (21.32 cc), specific gravity (1.02). pulp weight (15.94 g) and stone weight (3.06 g) were also found maximum in pink polypropylene bag in combination with 40 days after fruit set. Pink polypropylene bag in combination with bagging at 40 days after fruit set also showed great effects in terms of chemical parameters of fruits viz., total soluble solids (22.48°Brix), titratable acidity (0.40%), TSS: acid ratio (56.20). ascorbic acid (24.68 mg/100 g), total sugars (17.10%), reducing sugars (12.83%), non-reducing sugars (4.06%), anthocyanin content (54.35 mg/100g).
