Aims: We examined the cytological response of generative cells in different varieties and types of wheat under salt stress to understand how the physiological state of plants is related to growth conditions and productivity.Study Design: This study was conducted in the Laboratory of Cell engineering, Institute of Plant Biology and Biotechnology Science Committee of the Ministry of Education and Science of the Republic of Kazakhstan from 2011-2012.Methodology: The material for cytological studies served as the young ears are not released from the vagina of the upper leaves of various types of wheat subjected to the stage of stem elongation weak chloride salinity and without saline (control).Between 20 and 25 flowers on each ear were selected for cytological experiments.Samples were prepared and microsporocytes in the anthers were examined for at least 10 fields of view.Results: In high-salt conditions (0.05% and 0.1% NaCl), viable fertile pollen grains were observed in all wheat species tested but teratological irregularities occurred during flower development and slowed both male and female gametophyte development.Conclusion: The possibility of the evaluation of the physiological condition of the wheat plants in relation to the conditions of growth and productivity changes by the presence of teratology flowers.
