Effect of pre-harvest treatments of paclobutrazol and calcium chloride on physical quality traits of mango cv. Amrapali

Abstract

The present investigation was carried out during 2017-2018 in mango to find out the effect of pre-harvest treatments of paclobutrazol and calcium chloride on physical quality traits of mango cv. Amrapali. The experiment was laid out in a completely randomized design (CRD) with twelve treatments and three repetitions. The analysis of data revealed the significant effect of paclobutrazol and calcium chloride on all the parameters under study.Paclobutrazol at 200 mg/l with CaCl2 at 1.5 per cent significantly increased fruit weight (244.52 g), fruit length (11.02 cm), fruit breadth (7.01 cm), fruit volume (206.81cm3), pulp to peel + stone ratio (3.34), yield (44.20 kg/tree) and fruit firmness (3.62 kg/cm2) of mango cv. Amrapali fruits. While, 100 mg/l paclobutrazol with 1.5 per cent CaCl2 application significantly increased shelf life (6.83 days). The same treatment significantly reduced PLW of fruit for 2nd, 4th and 6th day of storage (1.20%, 1.50% and 2.47%, respectively) and spoilage per cent (22.03%) of mango cv. Amrapali fruits.
