abstract
The experiment was conducted at Department of Horticulture, College of Horticulture, Dr. Balasaheb Sawant konkan Krishi Vidyapeeth Dapoli (MS) during 2020-21 to study the effect of post-harvest treatments of different chemical and plant growth regulators on physical and chemical characteristics of sapota fruits cv. ‘Kalipatti’ during storage at ambient condition. Fast ripening of Sapota fruits during post-harvest stage results in their short shelf life which leads to deterioration of their quality. Among various chemicals, calcium has received considerable attention in recent year due to its desirable effects maintain the TSS, titratable acidity, reducing sugars, total sugars and ascorbic acids (Sharma et al., 1996) ^[8]. The fruits were treated with calcium chloride 20000 ppm was found very effective in specific gravity (1.09), PLW (12.76 %), fruit firmness (0.81 kg/cm²) and minimum spoilage fruit (56.74%). The qualitative parameters such as titratable acidity (0.08), maximum TSS (22.34 0Brix), Reducing sugars (11.14 %), Total sugars (18.21 %) and ascorbic acid found (13.19 mg/100g) at 12th day of storage period.
