Bukhara plum is one of the most important stone fruits with a low shelf life. Zinc and boron are important nutritional elements required by fruit trees, which play an important role in the quality of fruits after harvest. Also, amino compounds and essential oils have been taken into consideration in increasing the storage life of fruits. Therefore, in a separate experiment, the role of zinc and boron foliar spraying and immersion of plum fruits in the amino composition of spiromidine and mint essence in the quality and quantity of Bukhara plum storage life was investigated. In the first experiment, the trees were sprayed with zinc and boron elements in one step. And fruit storage was checked during three weeks. In the second experiment, the fruits were treated with aspermidine at concentrations of zero, 2 and 5 ppm and mint essential oil control and mint application and after that, they were evaluated every week for 42 days six weeks of storage time. Fruit juice pH, fruit acidity TA, electrical conductivity EC, soluble solids TSS, taste index, fruit fresh weight, fruit firmness, vitamin C, phenol, and color indices were measured. The results of the first experiment showed that foliar spraying of zinc and boron caused an increase in traits such as fruit juice pH, fruit acidity, soluble solids TSS, fruit taste index TSS/TA, fruit fresh weight, fruit firmness, vitamin C and index Color values were measured in Bukhara plum fruit during storage. The results of the first experiment showed that the fruit taste index, soluble solids, fruit firmness and plum fruit color indices decreased significantly P<0.01. Sprinkling of zinc and boron caused an increase in traits such as fruit juice pH, fruit acidity, soluble solids TSS, fruit flavor index, fruit fresh weight, fruit firmness, vitamin C and color indices. The results of the second part of the experiment also showed that color indicators, fruit firmness, soluble solids, EC of fruit juice decreased during storage. Mint essential oil increased the fruit flavor index. Aspermidine at a concentration of 2 ppm increased fruit quality indicators such as acidity of soluble solids, fruit flavor index, fruit fresh weight, fruit firmness and L and A color index. It is recommended to spray zinc and boron and use spearmaiden 2 ppm to increase the storage of Bukhara plum fruit.
