In this regard, there is a need to study sowing qualities of sunflower seeds in specific soil and climatic conditions of cultivation to optimize agricultural technology, plant protection, and increase yield. The purpose of this study was to determine the degree of invariance of descriptive indicators and germination of ʻPoseidon 625ʼ Helianthus annuus L. seeds under the conditions of the Orenburg region. The experiments were carried out at the experimental site of the Botanical Garden of Orenburg State University, as well as in the laboratory of experimental botany of the Botanical Garden of Orenburg State University. 5 descriptive indicators were studied, the laboratory and soil germination of ʻPoseidon 625ʼ H. annuus seeds were evaluated in the Orenburg region. It was found that the most invariant indicators were seed length and 1000 seed weight ( Cv 9 and 2%, respectively). Seed weight of ʻPoseidon 625ʼ H. annuus is determined by seed length (at the level of statistical significance p &lt; 0.5). Laboratory and field germination are consistently high (88 and 85%, respectively). Field germination is determined by the rate of germination of 75% of the seeds. It was established that increase in temperature of medium at early stages of ontogenesis significantly reduced elongation period of ʻPoseidon 625ʼ H. annuus seedlings (0.8; p-level = 0.1). The climatic factor “humidity” was not a statistically significant indicator having at least some influence on the analyzed parameters of germination of ʻPoseidon 625ʼ H. annuus seeds.</p></abstract><trans-abstract xml:lang="ru"><p>В формировании устойчивой системы сельского хозяйства для каждой климатической зоны приоритетной целью становится повышение урожайности ряда товарных культур, таких как подсолнечник, с точки зрения и количества, и качества. В связи с этим необходимо изучить посевные качества семян подсолнечника в конкретных почвенно-климатических условиях возделывания для оптимизации агротехники, защиты растений, увеличения их урожайности. Цель исследования - определение степени инвариантности дескриптивных показателей и всхожести семян Helianthus annuus L. ʻПосейдон 625ʼ в климатических условиях Оренбургской области. Исследования проводили на опытном участке, а также в лаборатории экспериментальной ботаники ботанического сада Оренбургского государственного университета. Изучено 5 дескриптивных показателей, проведена оценка лабораторной и грунтовой всхожести семян H. annuus ʻПосейдон 625ʼ в условиях Оренбуржья. Установлено, что наиболее инвариантны показатели длины семени и массы 1000 семян ( Cv 9 и 2 % соответственно). Вес семян определяется длиной семени (на уровне статистической значимости р &lt; 0,5). Лабораторная и полевая всхожесть стабильно высокие (88 и 85 % соответственно). Полевая всхожесть определяется степенью прорастания 75 % семян. Установлено, что увеличение температуры среды на ранних этапах онтогенеза значительно сокращало период растянутости всходов (0,8; p-level = 0,1). Климатический фактор - влажность - не относится к статистически значимым показателям, оказывающим хоть какое-то влияние на анализируемые параметры прорастания семян H. annuus ʻПосейдон 625ʼ.</p></trans-abstract><kwd-group xml:lang="en"><kwd>sunflower</kwd><kwd>morphometric indicators</kwd><kwd>laboratory germination</kwd><kwd>soil sowing</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>подсолнечник</kwd><kwd>морфометрические показатели</kwd><kwd>лабораторное проращивание</kwd><kwd>грунтовый посев</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Исследование выполнено за счет гранта Российского научного фонда  № 23-76-10060, https://rscf.ru/project/23-76-10060/</institution></institution-wrap><institution-wrap><institution xml:lang="en">The study was supported by the Russian Science Foundation Grant No. 23-76- 10060, https://rscf.ru/project/23-76-10060/</institution></institution-wrap></funding-source></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Makarenko M, Usatov A, Tatarinova T, Azarin K, Kovalevich A, Gavrilova V, et al.
