Abstract: (10 Views) |
The effects of drought stress on several physiological and anatomical characteristics of the edible fig cultivars Sabz, Meti, Siah and Puzdembali , were investigated in 2024 in the research greenhouse of the Department of Biology, University of Shiraz. The experiment was conducted as a factorial experiment based on a completely randomized design with four replications. The measured traits included leaf number, fresh weight of shoots and roots, relative water content of leaves and roots, number and diameter of vessels, proline, antioxidants, soluble sugars, and soluble proteins. Significant differences were observed between the drought-stress and control treatments for all measured traits. The Puzdembali plants died as a result of drought stress; therefore, it was not possible to measure their traits. Drought stress reduced leaf number, relative water content of leaves and roots, and the number and area of xylem vessels. In contrast, it significantly increased xylem vessel diameter and the levels of proline, soluble sugars, antioxidants, and root proteins. Among the studied cultivars, Siah was the most drought tolerant, whereas Puzdembali was the most sensitive cultivar.
