Ziziphus mauritiana is one of the important fruits of tropical and subtropical regions, which is known as the third garden product of Bushehr province after palms and citrus. One of the features of the fruit is that it has the ability to reach both the tree and the post-harvest.Keywords: UV-C radiation, decay, calcium chloride and Indian side. One of the best ways to maintain fruit quality is to harvest the fruit at maturity before it reaches full maturity, and the other one is to use methods that maintain the quality of the side fruits while increasing storage life. The aim of this study was to investigate the effect of calcium chloride and UV-C treatments on storage life and fruit quality and fungal infection alongside Indian (ZizipHus maurtiana). This study was carried out as a factorial randomized complete block design in 1397. Treatments included fruit immersion in three levels of calcium chloride (0, 2% and 4%) and four levels of UV-C radiation (0, 15, 30 and 60 min). After chemical treatments during forty days storage, quantitative traits such as fruit weight loss, tissue strength, decay and shrinkage percentage and qualitative traits including vitamin C, titratable acidity, soluble solids, pH and chloropHyll a and b Measured. In order to determine the most important fungal disease (Alternaria) that causes fruit rot in Anbar, cultivate fragments of infected fruit on potato dextrose agar (PDA) medium and after further purification and detection of Alternaria spp. The caries caused by this fungus was monitored for 12 days. The results showed that different storage times and chemical treatments each had a significant effect on storage life and fruit quality and control of post-harvest fungal caries. Also, the results indicated that fruit treatment with 4% calcium chloride and 60 minutes UV-C had the greatest effect on quantitative fruit traits up to 40 days storage. Fruit treatment with 4% calcium chloride and 60 minutes UV-C in the first 10 days resulted in the
