Abstract: The unsuitable storage conditions and the type of date pack are one part of the biggest challenges in the palm industry. In this research, two date cultivars: Kabkab and Khasoui, microalgae with the name of Chlorella vulgaris at four levels, 0, 25%, 50% and 100% and time of storage in three levels 1, 2 and 3 months (90 days) were carried out as factorial experiment in a completely randomized design with three replications. Dry weight, moisture content, pH and rate of decay of fruits of both cultivars were measured in every 30 days. Based on the results, the effect of microalgae and different months sampling for all traits were significant at (p ≤ 0.01) level. The effects of Chlorella vulgaris at 25% level were higher than the other concentrations on the most traits and were stable until the second month, and then its effect was decreased. Results revealed that the effects of all treatments on the Khasouei cultivar were higher than the Kabkab date cultivar.
