Abstract

This experiment was carried out during 2015 and 2016 seasons on plum “Santa rosa”cv. fruits to study the effect of spray of three bioinsect (100,150,200g/100 l water)  and  moringa extract (100,150,200g/100 l water)  at preharvest on quality of fruits during postharvest of plum fruits. Stored fruits at 0-2c0 and RH.90-95%. Weight loss, decay , titratable acidity ,ssc  and anthocyanin content were determined .Fruits treated in  preharvest results showed that bioinsect  (150g/l) were highest compatibility than all treatments . The advancing of cold storage periods weight loss , decay, tss% and anthocyanin content increasing, while titratable acidity % decreasing during storage periods. Results indicated that  fruits were treated with  moringa extract (100,200g/l) had lower significant of weight loss, decay, titratable acidity and anthocyanin, while fruits were treated with bioinsect  (100) had higher tss% during storage period in both seasons.
