Sodium nitroprusside applications modulate cell wall degrading enzymes and preserves the postharvest quality of cold-stored mangoes Devi Darshan, Karan Bir Singh Gill, Parmpal Singh Gill, Kashish Bajaj, Rajbir Singh Boora New Zealand Journal of Crop and Horticultural Science, 2025 Mango fruit undergoes various physiochemical changes after its harvest that affect consumer acceptability. The present research work was carried out to evaluate the preservation effect of sodium nitroprusside (SNP) treatments on the postharvest quality of mango cv. Langra fruits at 12 ± 1°C for 35 days. The results revealed that SNP 1.0 mM treated fruits exhibited reduced weight loss (6.94%), decay incidence (8.05%), and activities of cell wall degrading enzymes like polygalacturonase and pectin methyl esterase in comparison to uncoated fruits on the last day of storage. Furthermore, the treatment maintained higher fruit firmness (56.77 N) along with fruit quality parameters like soluble solid content (16.24%), titratable acidity (0.20%), starch (4.99%), and, total flavonoid content (12.92 mg/100 g). Overall, SNP 1.0 mM combined with low-temperature storage was proved to be the most effective in extending the shelf life and preserving the quality characteristics of mango fruits.
Plant bioregulators induced manipulation in the yield attributes of mango cv. Langra Devi Darshan, Karan Bir Singh Gill, Mandeep Singh Gill, Nirmaljit Kaur Indian Journal of Horticulture, 2024 The present study was carried out in two successive years to evaluate the comparative efficacy of CPPU and NAA combination in improving the yield attributes of Langra mango. Higher fruit drop and low fruit retention are the most critical constraints for mango production under north Indian conditions. Fruit drop starts occurring just after fruit set and continues till harvest, leading to substantial economic loss to the growers. The foliar application of CPPU 10 ppm + NAA 20 ppm and CPPU 20 ppm + NAA 30 ppm immediately after the fruit set resulted in a significant reduction in fruit drop in comparison to the control (water spray). Various physical attributes like endocarp size (5.16 cm), pedicel length (1.20 cm), pedicel thickness (4.02 mm), fruit weight (248.12 g), fruit size (7.46 cm width and 9.83 cm length), fruit volume (243.52 cc), and specific gravity (1.02) got improved with CPPU 10 ppm + NAA 20 ppm followed by CPPU 20 ppm + NAA 30 ppm than the control. In conclusion, the spray of CPPU 10 ppm + NAA 20 ppm proved to be an effective treatment for managing fruit drop and improving yield attributes in Langra mango.

POSTHARVEST TREATMENTS OF HEXANAL AND SODIUM BENZOATE TO MAINTAIN QUALITY AND EXTEND SHELF LIFE OF WINTER SEASON GUAVA UNDER LOW-TEMPERATURE STORAGE K S Gill, B V C Mahajan Agricultural Research Journal, 2022 In the present investigation, comparative efficacy and potential of postharvest treatment of hexanal and sodium benzoate were evaluated for extending shelf life and maintaining edibility of guava cv. Allahabad Safeda. The fruits were subjected to 5 min dip in aqueous solutions of hexanal (0.005%, 0.01% and 0.015% v/v) or sodium benzoate (0.2mM, 0.4mM, 0.6mM) whereas, the control fruits were dipped in water. Corrugated fibreboard (CFB) boxes with paper lining were used for packing the treated fruits and were kept under cold storage conditions (6 - 8°C, 90–95% RH). Assessment of physicochemical and fruit quality parameters was done at 0 days (before treatment) and weekly interval in storage till 35 days. In general, a gradual decline was noted with time in fruit firmness, pectic substances, phenols, acidity and vitamin C content whereas, physiological loss in weight increased in the stored fruits. Hexanal at a dose of 0.01% v/v effectively minimized decay incidence, retained firmness, phenol content and reduced the pectin degradation by suppressing the pectin methylesterase (PME) activity. Similarly, the treated fruits retained higher TSS and TA during the storage as compared to other treatments. Sodium benzoate treatments also maintained the quality attributes better than the untreated fruit. It was concluded that postharvest dip treatment of Hexanal (0.01% v/v; 0.8 mM) extended the storage life of guava cv. Allahabad safeda from 14 to 21 days as compared to control.
