One potential strategy to mitigate environmental stress on plants is the utilization of a shade net. Changes in the environmental conditions on shade net, particularly with regards to luminosity and temperature, will invariably result in alterations in the biochemical reactions and quality attributes of the product. In light of the advancements made in shade net technology in Iran, the current study was undertaken to explore the impact of the green shade net with 30 percent shading on the quality attributes of apricots, Rajab Ali cultivar, at the Shahrood Agricultural and Natural Resources Research and Training Center on 2021-2022. Various parameters such as fruit length, diameter, weight, percentage of total soluble solids, titratable acidity, color, vitamin C, total phenol, total antioxidant capacity, and texture firmness were evaluated on treatment and control samples and subjected to t-test analysis at a 5% significance level. The findings indicate that the average weight of fruits during full ripening was 48.31 and 78.58 outside (control) and inside (treatment) shade net respectively. The difference between the color of the samples inside and outside the canopy was significant. The value of a* in the control samples was higher than its value in the treatment samples. A significant difference was observed between the amount of total phenol and total antioxidant activity between treatment and control. Total soluble solids were 13.71% and 13.10% respectively in the control and treatment at the stage of fruit ripening. According to the results, the use of shade net until the end of fruit ripening on apricot trees (6 months), in addition to changing the quality characteristics, also causes late fruit ripening.
