ABSTRACT
The present study was conducted to know the influence of chemicals and plant bioregulators application during the time of fruit developmental phenophase on fruit weight, quality and shelf-life of Mango (Mangifera indica. L) at the fruit research station, Aswaraopet, Telangana, India during the 2022- 23. Among chemicals and plant bioregulators maximum fruit retention percentage (16.851 %), TSS (14.901 °Brix), total sugars (12.999 %) and shelf life (15.034 days) were recorded with pre-harvest application of CPPU. Maximum ascorbic acid content (49.838 mg. 100 g-1), reducing sugars (4.277 %) and firmness (5.866 kg.cm-2) were recorded with pre-harvest application of Ca(NO3)2 whereas, minimum physiological loss in weight was recorded with the application of CPPU on 12th day (16.244 %). Among different time of chemicals and plant bio regulator application, maximum fruit retention percentage were recorded with chemicals and plant bio regulator applied at 703 phenophase, maximum shelf-life was recorded with the application of CPPU at 709 phenophase, minimum physiological loss in weight was recorded with the application of CPPU at 709 phenophase.
