Effects of Soil Water Content on the Postharvest Quality of Mango Fruit

To provide a theoretical basis for the water management of mango fruit growth period and postharvest storage of mango of mango,By field experiment,studying on the effects of the different soil water content on postharvest mango fruit edible rate,soluble sugar,fruit water loss rate etc.The results showed that,at the stage of fruit ripening,the soluble solids content changed in inverted V type.A treatment soluble solids content was lower than other treatments,when fruit ripped,soluble solids content of A treatment was significantly lower than that of C treatment;While the soluble sugar content increased gradually,soluble sugar content of B treatment was significantly higher than that of E treatment;Starch content gradually reduced,in the fully mature period,starch content of A treatment was the highest.At the stage of fruit ripening,the titratable acid content gradually decreased.Compared with CK,when fruit full ripeness,A~E treatments titratable acid increased by respectively 13.89%,11.80%,27.39%,14.91% and 32.38%.At the stage of fruit ripening,VCcontent gradually decreased,when the full ripeness,other treatments VCcontent were higher than that of CK,C treatment was the largest.With fruit full ripeness,CK soluble protein increased gradually,A~E treatments first increased and then became flat.A~D treatments fruit water loss rate was greater than CK,E treatment was lower than that of CK,A treatment and CK fruit water loss rate reached a very significant difference.A treatment fruit edible rate was lower than CK,the other treatment was higher than that of CK,but the difference was not significant.
