Биология семян растений рода Pennisetum Rich. мало изучена. Высокая семенная продуктивность, благоприятные температурные условия хранения не всегда дают высокий процент всхожести семян при выращивании их в открытом грунте. Замачивание семян в стимуляторах роста является перспективным способом повышения их посевных качеств.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Материалом для исследования были выбраны семена 5 сортов P. glaucum (L.) R.Br. и двух видов P. setaceum (Forrsk.) Chiov. и P. villosum R. Br. ex Fresen. 2022–2023 гг. сбора с периодом хранения 6 и 24 месяца. Подготовленный семенной материал замачивали в 5 растворах ростостимуляторов: Эпин-Экстра, HB-101, Бона Форте Эликсир, Хлорелла, Биогумат+9. Энергию прорастания и всхожесть определяли в соответствии с ГОСТ 12038−84.</p></sec><sec><title>Результаты</title><p>Результаты. В результате эксперимента было определено положительное влияние стимуляторов роста на динамику прорастания семенного материала у всех видов и сортов Pennisetum. Для всех сортов P. glaucum препараты НВ-101 и Эпин-Экстра оказались менее эффективными на семенах 2023 г. с наименьшим периодом хранения. Выявлены средние и высокие показатели лабораторной всхожести у семян 2022–2023 гг. сбора и у единичных сортов P.glaucum 2023 г. со сроком хранения 6 мес. Для достижения высоких показателей всхожести, свыше 80% у сортов P. glaucum рекомендуем применять препараты на семенном материале с периодом хранения от 24 месяцев. Из всех изученных препаратов существенное увеличение показателей всхо жести на семена  P. setaceum оказали препараты Биогумат+9, Хлорелла, Эпин-Экстра, для P. villosum — Биогумат+9 и Бона Форте Эликсир.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Relevance</title><p>Relevance. Biology of seeds of plants of the genus Pennisetum Rich. little studied. High seed productivity and favorable temperature storage conditions do not always provide a  high percentage of seed germination when grown in open ground. Soaking seeds in growth stimulants is a promising way to improve their sowing qualities.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Five varieties of P. glaucum (L.) R.Br. and two species of P. setaceum (Forrsk.) Chiov. and P. villosum Br. ex Fresen. were chosen as the material for the study. The prepared seed material was soaked in 5 solutions of growth stimulants: Epin-Extra, HB-101, Bona Forte Elixir, Chlorella, Biohumate + 9. Germination energy and germination were determined in accordance with GOST 12038−84.</p></sec><sec><title>Results</title><p>Results. As a result of the experiment, a positive effect of growth stimulants on the germination dynamics of seed material was determined for all species and varieties of Pennisetum. For all varieties of P. glaucum, the preparations HB-101 and Epin-Extra were less effective on seeds of 2023 with the shortest storage period. The average and high laboratory germination rates were found in seeds harvested in 2022–2023 and in individual varieties of P. glaucum harvested in 2023 with a shelf life of 6 months. To achieve high germination rates of over 80% in P. glaucum varieties, we recommend using seed treatments with a shelf life of at least 24 months. Of all the studied preparations, Biohumate+9, Chlorella, and Epin-Extra had a significant effect on the germination rate of P. setaceum seeds, while Biohumate+9 and Bona Forte Elixir had a significant effect on the germination rate of P. villosum seeds.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Pennisetum</kwd><kwd>сорт</kwd><kwd>вид</kwd><kwd>качество семян</kwd><kwd>замачивание семян</kwd><kwd>энергия прорастания</kwd><kwd>лабораторная всхожесть</kwd><kwd>стимуляторы роста</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Pennisetum</kwd><kwd>variety</kwd><kwd>species</kwd><kwd>seed quality</kwd><kwd>seed soaking</kwd><kwd>germination energy</kwd><kwd>laboratory germination</kwd><kwd>growth stimulants</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания  Министерства науки и высшего образования РФ  (№ 1021060207393-6-1.6.11) Амурского филиала Федерального государственного бюджетного учреждения науки Ботанического сада-института Дальневосточного отделения Российской академии наук</funding-statement><funding-statement xml:lang="en">This study was supported ty the state task of the Ministry of Science  and Higher Education of the Russian Federation, project (No. 1021060207393-6-1.6.11) of the Botanical Garden-Institute of the Far Eastern Branch of the Russian Academy of Sciences</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Коротков А.А., Кох Ж.А.
