Abstract

Poor quality fruit is one of the major constraint in Mango production. Since, bio-stimulants has a role in improving quality of fruits, a field experiment was carried out in ZAHRS, Hiriyur, during the year 2021-22. The experiment was laid out in RCBD comprising of nine treatments viz., T1 – control, T2 - jasmonic acid (100 µM), T3 - jasmonic acid (150 µM), T4 - salicylic acid (100 ppm), T5 - salicylic acid (150 ppm), T6 - brassinosteroid (0.40 ppm), T7 - brassinosteroid (0.60 ppm), T8- triacontanol (7.5 ppm) and T9 - triacontanol (10.0 ppm) with four replications, sprayed at an interval of 70 and 90 days after anthesis. Among the treatments, T5 - salicylic acid (150 ppm) recorded maximum TSS (22.86 ºB), reducing sugars (6.29%), total sugars (15.72%), sugar-acid ratio (44.62), total carotenoids and flavonoids (5.56 mg/100g and 30.63 mg QE/100 g, respectively), proline content (23.42 µg/g of fw), total antioxidant activity (42.10%), shelf life (14.75 days) and highest score for organoleptic evaluation with minimum titratable acidity (0.35%) and moisture content (76.58%).

Keywords

Mango, Mallika, bio-stimulants, quality attributes

Conclusion

Based on the above results, it can be concluded that salicylic acid @ 150 µM showed its potentiality in improving quality by recording maximum TSS, reducing non-reducing and total sugars, sugar-acid ratio, total carotenoids and flavonoids, proline, total antioxidant activity, shelf life with minimum acidity and physiological loss in weight in mango cv. Mallika under central dry zone of Karnataka sprayed at an interval of 70 and 90 days after anthesis.
