Abstract

Mango varieties are susceptible to different postharvest defects like spongy tissue, anthracnose, fruit fly and stem end rot and their intensity depends on growing conditions and locations. Limited information is available on the influence of locations on these defects. In this study, different geospatial parameters viz. altitude, temperature, rainfall, humidity, soil nutrients were analyzed to assess their impact on the quality and postharvest defects in mango var. Alphonso. Panicles were tagged thrice with an interval of 10 days at different locations viz. Bengaluru, Chikkaballapura, Hogalgere and Ramanagara (about 228km distant from each other). Mangoes were harvested and quality was analyzed. Results revealed that, fruits from Hogalgere were free from fruit flies but had highest incidence of spongy tissue (20.9%). The fruits from Chikkaballapura had highest fruit fly infestation (30%). Anthracnose infection was highest in fruits from Bengaluru (11.9%). Stem end rot was highest in f

Conclusion

All the postharvest defects and quality attributes have deep connection with geospatial conditions and time of harvest, hence location specific pre and postharvest practices is inevitable. Postharvest defects stem end rot and anthracnose occurred in all the locations whereas, fruit flies and spongy tissue was location specific. Harvesting at optimum maturity maintains the qualities and the fruits harvested from early emerged panicles had fewer incidences of defects than the subsequent ones. Postharvest management of fresh mangoes is a challenging, however, understanding geospatial condition and its intricate correlation details may aid in maintaining the postharvest quality and extending the shelf life of mangoes. Long term assessment of heat units required in different locations may be calculated to aid in staggered harvesting in different locations to avoid the postharvest defects and ultimately preserving the post harvest quality and shelf life.
