The influence of drought stress on some physiological and biochemical parameters of wheat
2022
Wheat is a staple food and a source of protein and carbohydrates for 35% population in the world. Drought is one of the main environmental factors negatively affects wheat production and quality. We aimed to study the effect of drought stress on some physiological, morphological, biochemical parameters of 5 durum and 8 bread wheat genotypes. The assimilation surface area of leaves, stem, spike and dry biomass in this organ negatively affected by drought stress. Due to water deficiency relative water content, photosynthetic pigments content are reduced. Wheat genotypes responded to drought stress to conserve water by accumulating soluble sugars and proline. The malondialdehyde content increased indicating oxidative stress caused by drought. Genotypic differences for studied parameters was revealed.
