|Abstract||An investigation entitled â€œEffect of Ripening Agents on Physiology, Biochemical Compounds and Shelf Life of Mango (Mangifera indica L.) cv. Dashehariâ€ 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 5Â±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 Î¼mg 100g-1pulp), PG (9.10 Î¼g 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 Î¼mg 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 (5Â±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 (5Â±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.|

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
