- W3048698995 abstract "Purpose. To reveal the characteristics of microsporogenesis and microgametogenesis in plants derived from frozen sprouted seeds and mitosis in rootlets of germinating seeds from plants of the next generation and to determine seed vigor and seed laboratory germination. Methods. Cytological analysis of mitosis and meiosis was carried out in cells of plants obtained after freezing and control (no freezing). Seed vigor and seed laboratory germination were determined according to the methods of the State Standard of Ukraine. The statistical significance of differences was assessed according to the Student’s t-test. Results. It was conducted cytological analysis of mitosis in rootlets of seedlings from seeds derived from bread winter wheat plants which survived after evaluation of frost resistance by the method of freezing sprouted seeds at temperature of minus 20 оC. All samples analyzed had hexaploid set of chromosomes 2n = 6x = 42. The proportion of cells with mitotic anomalies in rootlets of seedlings of seeds obtained both after the effect of temperature stress and in the control variant did not exceed 1.5 %. It was found that the meiosis in experimental plants at the stages of microspores and microgametogenesis almost does not differ from the control ones in terms of the number of disorders (2 %) and their spectrum. The proportion of fertile pollen in the control and experimental material was more than 70 % being sufficient for normal pollination of wheat. The low temperature did not adversely affect vegetative and generative organs of plants which have survived after freezing, since the main seed rate –germination – well corresponded to the level of certified seeds. Conclusions. It was found that when determining frost resistance and winter hardiness of winter wheat by the method of freezing sprouted seeds, the low temperature (-20 °C) does not adversely affect mitosis and meiosis processes in the plants survived, since the frequency of disorders did not exceed 2 %, the proportion of fertile pollen was 77–86 %, and seed laboratory germination was at the level of certified seeds (92–96 %). The data obtained can be used to improve the efficiency of targeted selection when creating highly productive, highly adaptive breeding material." @default.
