Response of Contrasting Rice Genotypes to Zinc Sources under Saline Conditions

Abiotic stresses are among the major limiting factors for plant growth and crop productivity. Among these, salinity is one of risk development in arid to semi-arid regions. Cultivation salt tolerant genotypes imperative approaches meet food demand increasing population. The current experiment was carried out access performance different rice under stress Zinc (Zn) sources. Four were grown a pot exposed (7 dS m?1), Zn (15 mg kg?1 soil) applied from two sources, ZnSO4 Zn-EDTA. A control both kept comparison. Results showed that based on biomass accumulation K+/Na+ ratio, KSK-133 BAS-198 emerged as sensitive, respectively. Similarly, concentration, BAS-2000 reported Zn-in-efficient while IR-6 Zn-efficient genotype. Our results also revealed growth, relative water content (RWC), physiological attributes including chlorophyll contents, ionic concentrations straw grains all decreased stress. However, significantly higher shoot K+ saline conditions. application alleviates harmful effects by improving morpho-physiological enhancing antioxidant enzyme activities, uptake K Zn. beneficial effect more pronounced salt-tolerant in-efficient compared with salt-sensitive genotypes. In sum, our confirmed increased overall plant’s conditions, particularly efficient
