Influence of sodium chloride on morphophysiological characteristics of wheat and maize plants

Aim. The effect of sodium chloride on the physiological and biochemical parameters wheat maize genotypes, identification salinity-resistant varieties was studied. Wheat plants were grown in pots soil with addition 0.5 % chloride. To create new salt-tolerant maize, a comparative analysis morphophysiological carried out. Methods. Morphophysiological such as growth, chlorophyll carotenoid content, photochemical activty chloroplasts PSII activity have been studied plant. Results. salt amount a, b, carotenoids, which are main indicators, is manifested different ways both plants. When studying salt-tolerance plants, differences detected relative amounts (a+b), well efficiency PS 2. Conclusions. Among varieties, according to all parameters, most tolerant action soft variety Mirbashir-128, corn hybrid Belaya x Gurur.
