Abstract:   (1058 Views)
One protected horticultural method against biotic and abiotic stresses is shading covers. Using shading cover to reduce the damage of this stress can change the plant's microclimate and, subsequently, the final product's quality. This study aimed to investigate the effects of shading cover on grape quality. The grapevines were subjected to shading cover cloth with green color from March to September for two years. In the first year of the experiment, a shading cover with 50% shade was used for Bidaneh Sefid grape variety, and the result indicated that this percentage of shade reduced the final fruit quality. In the second year of the experiment, 20% shade was used for Bidaneh Sefid and Bidaneh Ghermez varieties. Results showed that this shading percentage improved the physical properties of the fruit, especially in the Bidaneh Sefid variety. Soluble solid content, titratable acid, and vitamin C of both grape varieties were not affected by 20% shade. Like 50% shade, total phenol and antioxidant capacity were decreased by 20% shade in both grape varieties. Further research for different shade percentages on different crops and cultivars in every climate will be necessary to develop shading cover technology for horticulture crops in Iran.
