The effect of coting peach (Prunus persica L.) on increasing shelf life after harvesting

Considering the high waste after peach harvest, it is very important to provide suitable solutions to increase the shelf life of this fruit after harvest. One of the ways to increase the shelf life of fruits after harvesting is to use nature-friendly substances such as vegetation and the use of hormones. For this purpose, an experiment was conducted to investigate the effect of vegetation cover in a factorial form in a completely randomized design in four replications on peach ( Prunus persica L.). Research treatments included salicylic acid at three levels: control (no consumption), 1 mM and 2 mM, aloe vera gel at three levels control (no consumption), 20% and 30%, clove extract ( Syzygium aromaticum ) at three levels of no consumption (control), 150 ppm and 300 ppm. The results of this research showed that the use of coating fruits with plant extracts and salicylic acid increased the shelf life and quality of peaches after harvesting compared to the control (no consumption), so the highest fruit weight 24.65 g was seen in salicylic acid 2 mM, 73.68 g aloe vera gel 30%, and 62.75 g clove extract 300 ppm. The lowest this index was observed in control. The highest total antioxidant 509.75 m mol.l − 1 , was observed in the interaction of salicylic acid 2 mM + aloe vera gel 30% + clove extract 300 ppm. The lowest of this index 320.53 m mol.l − 1 was seen in control.
