В настоящее время основными нормируемыми показателями при сертификации партий посевного материала, определяющими его хозяйственную годность, являются энергия прорастания и всхожесть. Однако они не позволяют достоверно прогнозировать полевую всхожесть. Цель исследований – изучить влияние продолжительности хранения на посевные качества семян сортов люцерны по комплексу показателей, включающих определение всхожести, энергии, дружности и скорости прорастания, ее индекса, а также динамического процесса герминации семян. Анализ кинетики прорастания семенного материала при двух температурных режимах – +10 и +20 °С – позволил выявить общую закономерность: у всех сортов максимальное количество семян прорастало после 1 года хранения. В условиях более высокого температурного фона скорость прорастания семян после их хранения на протяжении от 1 года до 12 лет уменьшалась на 35–62 %. Корреляционный анализ взаимосвязи энергии и дружности прорастания семян после их хранения на протяжении от 1 года до 6 лет при режиме проращивания +20 °С выявил тесную зависимость этих показателей (r = 0,882). Взаимосвязь этих параметров на фоне проращивания семян при +10 °С также была высокой (r = 0,838). В соответствии с требованиями ГОСТ Р 52325-2005 сохранение стандартных показателей всхожести у семян сорта Вела наблюдалось на протяжении 6,5–7,5 года, у сорта Воронежская 6 – до 7,5 года и Павловской 7 – до 8,5 года.</p></abstract><trans-abstract xml:lang="en"><p>Sowing qualities of seeds determine the potential of the initial development of plants at the initial stages of their ontogenesis. Currently, the main standardized indicators in the certification of batches of seed material, determining its economic suitability, are germination energy and germination. However, they do not allow to reliably predict field germination. The purpose of the research is to study the effect of storage duration on the sowing qualities of seeds of alfalfa varieties by a set of indicators, including the determination of germination, energy, uniformity and rate of germination, its index, as well as the dynamic process of seed germination. Analysis of the kinetics of seed germination at two temperature regimes – +10 and +20 ° C – revealed a general pattern: in all varieties, the maximum number of seeds germinated after one year of their storage. At a higher temperature background, the rate of seed germination after their storage for 1 to 12 years decreased by 35–62 %. Correlation analysis of the relationship between the energy and uniformity of seed germination after their storage for 1 to 6 years under the germination regime of +20 °C revealed a close dependence of these indicators (r = 0.882). The relationship of these parameter indicators against the background of seed germination at +10 °C was also high (r = 0.838). In accordance with the requirements of GOST R 52325-2005, the preservation of standard germination indicators in the seeds of the Vela variety was observed for 6.5–7.5 years, in the Voronezhskaya 6 variety – up to 7.5 years, and in the Pavlovskaya 7 variety – up to 8.5 years.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>люцерна</kwd><kwd>сорта</kwd><kwd>посевные качества семян</kwd><kwd>длительность хранения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>alfalfa</kwd><kwd>varieties</kwd><kwd>sowing qualities of seeds</kwd><kwd>storage duration</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Бабайцева, Т.
