Effect of pruning and growth regulators on quality of pomegranate Cv. Bhagwa

The research was conducted on effect of different levels of pruning and plant growth regulators quality of pomegranate (Punica granatum L.) Cv. Bhagwa. The experiment was laid out with three replications and twenty treatments. Among of different levels of pruning, (pruning 10 cm, pruning 20 cm, pruning at 30 cm and control (Unpruned) in hasta bahar crop of pomegranate, pruning at 30 cm recorded maximum fruits firmness (5.99 kg/cm2), fruits peel thickness (2.19 cm), fruit weight of 100 aril (33.07 g), Specific gravity (1.52 g/cc),total soluble solids (16.52 oBrix), observed in pruning at 20 cm. total sugars (15.41%), it was recorded in pruning at 30 cm, reducing sugars (8.46%),in control (unpruned). non-reducing sugars (6.86%), recorded in pruning at 30 cm. titrable acidity (0.68%) recorded between pruning at 20 cm and pruning at 30 cm both of equals. and ascorbic acid (13.53%), recorded between pruning at 20 cm and pruning at 30 cm both of equals shelf life (16.20%) showed significant results in pruning at 10 cm. Among plant growth regulators (NAA @ 25 ppm, NAA @ 50 ppm, GA3 @ 25 ppm, GA3 @ 50 ppm and water spray) in hasta bahar crop of pomegranate, GA3 @ 50 ppm recorded maximum fruit firmness (6.21 kg cm-2), fruits peel thickness (2.24 cm), and weight of 100 aril (34.83 g), Specific gravity (1.54 g/cc) significantly total soluble solids (16.51 oBrix), reducing sugars (8.57%) was observed in GA3 @ 50 ppm, non-reducing sugars (6.92%), titrable acidity (0.75%) and total sugars (15.29%) was observed in water spray, shelf life (16.25%). The interaction between different levels of pruning and plant growth regulators shown maximum, fruit firmness (6.29 kg cm-2), fruits peel thickness (2.30 cm) weight of 100 aril (37.60 g), Specific gravity (1.63 g/cc), maximum total soluble solids (17.10 oBrix), total sugars (16.40%), reducing sugars (10.00%) and non-reducing sugar (8.56%) non-reducing sugar (8.56%) with same above treatment combinations.
