Impacts of Ascorbic Acid and Alpha-Tocopherol on Chickpea (Cicer arietinum L.) Grown in Water Deficit Regimes for Sustainable Production

Drought is a major abiotic stress forced by the changing climate that affects plant production and soil structure functions. A study was conducted to explore impacts of ascorbic acid (AsA) ?-tocopherol (?-toc) on agro-physiological attributes antioxidant enzymes chickpea grown in water deficit regions. The results analysis showed electrical conductivity (EC) pH were decreased from 521 mS/m 7.08 151 6.6 20-day drought regimes, respectively. Agronomic outcomes exogenous application AsA ?-toc increased germination rate index (GRI), mean time (MGT), energy (GE), use efficiency (WUE), percentage (GP), seed vigor (SVI). However, all above experienced decline under 10- stress. Similarly, Chl. a, b, carotenoids, proline, protein, sugar, glycine betaine, hydrogen peroxide contents significantly increased. Meanwhile, malondialdehyde, glutathione reductase, enzymatic antioxidants (APOX, SOD, POD) during drought, except CAT, which drought. fertigation these growth regulators improved photosynthetic pigments non-enzymatic stressed plants. current research concludes simultaneous dusting could be an efficient technique mitigate antagonistic might linked regulation defense systems.
