EFFECT OF Na-ISOCATED SALT SOLUTIONS ON GROWTH CHARACTERISTICS OF WHEAT PLANT SEEDS

Abstract

Our planet is mainly a saline planet. Because most of its surface is covered with salt water (sea and ocean waters contain 3% NaCl salt), and due to evaporation, some of these salts gradually settle to the Earth's dry surface, causing soils to become saline. Today, 900 million hectares of arable land are exposed to salinity stress. Increased levels of water-soluble salts in the soil, such as NaCl, Na2SO4, Na2CO3, CaCl2, are often associated with irrigation and are a major factor in soil salinization. Salinization, in turn, affects the physiological and biochemical processes in plants, leading to a decrease in their biomass and productivity.
