A Comparative Analysis on Morphological and Physiological Characteristics between Castor Varieties (Ricinus communis L.) under Salt Stress

Salt stress is one of the main abiotic factors affecting castor yield. Wild resources can provide important insights for cultivated breeding. However, little known about how wild responds or adapts to salt stress. To understand physiological mechanisms tolerance in castor, morphological and responses two varieties, with contrasted were characterized under Seedlings exposed 0, 50, 100 mM NaCl. The results showed that application significantly inhibited increase chlorophyll content relative water castor. degree electrolyte leakage was less than In addition, WT a lower reactive oxygen species (ROS) compared CT. activities antioxidant enzymes like SOD, APX, GR, MDHAR leaves higher accumulation those CT ratio ASA/DHA GSH/GSSG distinct summary, our revealed resistance characteristics also has potential be used as parental material breeding program. These will valuable
