Influence of pre-harvest treatments of paclobutrazol and calcium chloride on biochemical and sensory attributes of mango cv. Amrapali

Abstract

A field experiment was conducted during 2017-18 to study the influence of pre-harvest application of paclobutrazol and calcium chloride on biochemical and sensory attributes of mango cv. Amarapali. The experiment was laid out in a completely randomized design (CRD) with twelve treatments and three repetitions. Paclobutrazol and CaCl2 were sprayed at 75 days after full bloom and 15 days before harvest, respectively on 10 years old mango orchard planted at 2.5 m × 2.5 m spacing. Paclobutrazol at 100 mg/l with CaCl2 at 1.5 per cent significantly increased TSS (20.70 °B), total sugar (17.65%), reducing sugar (7.16%), ascorbic acid (41.08 mg/100 g), total carotenoids (0.99 mg/100 g) and phenol (86.53 mg/100 g) of mango cv. Amrapali. The same treatment significantly reduced titratable acidity (0.13%) of mango cv. Amarapali fruits.
