Effect of different planting materials and chemicals on the fruit quality of Pomegranate (Punica granatum L.) cv. Bhagwa

Abstract

The quality parameters like total aril weight, percentage of aril weight, 100 aril weight, TSS, titrable acidity and anthocyanin content were seen in plants grown from tissue culture plants, followed, in that order, by grafts and air layers. Soil drenching with paclobutrazol (0.375 g of the active ingredient per metre of canopy diameter), foliar spray of nitrobenzene (2.0 ml/l) 60 days following the measures to induce stress and methyl jasmonate were the most effective treatments to increase the total aril weight (108.57 g, 122.73 g), percentage of aril weight (57.06%, 57.42%), 100 aril weight (28.77g, 32.86g), TSS (19.54 0B, 15.01 0B), titrable acidity (0.44%, 0.61%) and anthocyanin content (3.59 mg / 100g, 4.62 mg / 100 g) in ambe bahar and hastha bahar seasons. Soil drenching of paclobutrazol @ 0.365 g a.i. m-1 canopy diameter, foliar spray of nitrobenzene @ 2.0 ml litre-1 and methyl jasmonate @ 200 ppm litre-1 were most effective in improving fruit quality and anthocyanin content.
