Negative effects of climatic changes on shelf life and quality of ?Keitt? mango

Exposure to elevated temperatures during growing season may cause physiological and ultimately, biochemical changes in plant tissues (including fruits) and, as a consequence, hasten ripening and other associated events. ? The present study aimed to investigate the impact of changes in some climate factors include temperature, relative humidity (RH) and light intensity on shelf life and the incidence of jelly seed disorder in mango fruits. ? To investigate the changes in climatic factors, mango plantlets were transplanted under two different conditions: open field and net cover (30% shade). All plantlets were grafted on balady rootstock, grown in sand soil in an orchard located at Elboseily region, Beheira governorate North West Egypt and subjected to similar agricultural practices. ? ? Seven years later, the present study was carried out during 2012 and 2013 seasons. Mature fruits were harvested, stored in carton boxes under ambient temperature and investigated two days intervals until ripe stage. ? Results showed that high temperature (in open field) during the growing season accelerated respiration rate and softening, hence hastened fruit ripening and shortened shelf life of ?Keitt? mango fruit. ? Internal breakdown (jelly seed) incidence was higher in open field fruits than those grown under net cover fruits. ? The present results suggested that increasing warming of the planet and high preharvest fruit temperatures negatively affect fruit quality and shelf life of mango fruit. The role of climatic factors in enzymatic activities, ripening and internal breakdown of mango was widely discussed.?
