Effect of sodium chloride on physiological and biochemical indices of wheat and maize genotypes
Abstract
Aim. Study the effect of sodium chloride on the physiological and biochemical characteristics of wheat and maize genotypes, to identify varieties tolerant to salinity. To create new salt-tolerant varieties of wheat and maize, a comparative analysis of the physiological and biochemical parameters of the parental and hybrid plants was carried out. Methods. Physiological parameters such as chlorophyll content, relative water content, and PSII activity have been studied in parental forms and hybrids. Results. Based on the physiological indices determined during the grain filling stage, the highest tolerance was manifested by the parental forms, Garabagh, Gobustan, and the hybrids, ♀Garabagh×♂Gobustan, ♀Garabagh×♂Mirbashir, ♀Garabagh×♂Sharg. The varieties Gurur and Zagatala-68 and hybrid “Gurur×Zagatala-68” were resistant to 200 mmol salt concentration.The varietiesofmaize Gurur and Zagatala-68 were resistant to 200 mmol salt concentration
