Abstract An investigation entitled “Effect of Ripening Agents on Physiology, Biochemical Compounds and Shelf Life of Mango (Mangifera indica L.) cv. Dashehari†was carried out during June-Dec. 2016 at Department of Horticulture, Rajasthan College of Agriculture, Udaipur. During the study the mango fruits were treated with fourteen different ripening agent(s) viz. Control (T0) ethephon (T1) dried palash (Butea monosperma) leaves (T2) Wet Kachnar (Bauhinia variegata) leaves (T3), Wet Amaltas (Cassia fistula) leaves (T4), Dried wheat straw (T5), Rice straw (T6), Newspaper (T7), White paper (T8), Tissue Paper (T9), Brown paper bag (T10), Wheat grain (T11), Jute bag (T12), Cardamom (T13) for six days. These treatments were evaluated under completely randomized design with four replications. Physicochemicals parameters, quality attributes, enzymes activities, sensory and colour evaluation of samples were observed at daily basis till fruit get ripened upto 6th day, and the shelf life of mango fruit was evaluated under low temperature storage at 5±2oC (up to 16th day) however, all storage parameters were examined at 4 days interval. The result revealed that mango treated with T2 treatment i.e. dried palash (Butea monosperma) leaves increase the uniform ripening (up to 6th day), minimize the PLW (10.12%) and acidity (1.60%) and resulted maximum in ethylene production (151ppm), respiration rate (114.85 ml CO2 kg-1h-1), ripening index (7.24%), TSS (26.10 oBrix), ascorbic acid (34.20 mg 100g-1of pulp), total sugar (19.50), total carotenoids (21.54 μmg 100g-1pulp), PG (9.10 μg PGN min-1), PME (0.81 A620min-1), organoleptic score (8.5), no decay, B:C ratio (1.81) and even similar treatment increase the shelf life (16th day) of mango which was statistically superior to enhance the quality i.e. ripening index (7.44), TSS (27.12 0Brix), ascorbic acid (31.20 mg 100 gm-1), total sugar (20.12 %), carotenoids (22 μmg 100g-1pulp ), CIE L*(74), CIE chroma (58.83), organoleptic score (8.55) and minimum acidity (0.16 %), physiological loss in weight (12.23%) and no decay under low temperature storage in (5±20C). This treatment was closely followed by T4 treatment Wet Amaltas (Cassia fistula) leaves and T3 Wet Kachnar (Bauhinia variegata) leaves at room temperature and storage temperature (5±20C) Thus, mango ripening with palash (Butea monosperma) leaves gave superior quality of ripened of mango, its better self life during the storage and also found economically feasible as compared to rest of the treatments hence, it may be recommended as suitable ripening agent for mango.
