Томат считается важной овощной культурой, которая играет большую роль в сохранении здоровье человека, поэтому исследования морфологических, физиологических и пищевых свойств томата актуальны. Фермеры часто используют некоторые химические вещества, которые имеют сходную структуру и активность с эндогенным растительным гормоном, называемым (экзогенным), в качестве недорогой альтернативы для регулирования роста растений и увеличения урожайности. Влияние многих из этих веществ на рост и качество сельскохозяйственных культур еще не изучено.</p></sec><sec><title>Методика</title><p>Методика. Целью данного исследования является оценка влияния четырех регуляторов роста (Крезацин, Хитозан, Циркон и Энерген) на рост, продуктивность и качество двух российских сортов томата (Моряна и Супергол) в условиях дельты Волги.</p></sec><sec><title>Результаты</title><p>Результаты. Результаты показали, что использование Энерген на сорте Моряна усилило большинство изученных признаков (всхожесть – 83,1%, свежая масса вегетативных частей – 241,9 г, сухая масса вегетативных частей – 74,4 г, количество цветков / растений – 51,0, количество плодов / растений – 35,6, урожайность растений – 2,44 кг, сумма сахаров – 5,1°Brix, содержание аскорбиновой кислоты – 25,6 мг/100 г. Применение Энергена на сорте Супергол дало максимальное значение высоты растений (85,6 см), массы плода (72,6 г); в то время как при использовании Крезацина на сорте Mоряна было достигнуто самое высокое содержание сухого вещества в плодах (6,77%) и кислотность (0,53%). Применение Циркона на сорте Моряна привело к увеличению количества листьев на растении (56,8) и содержания нитратов (27,6 мг/кг). Максимальный LAI (150,1 см2 ) получен при использовании хитозана на сорте Супергол, тогда как его применение на сорте Моряна дало самый высокий уровень каротиноидов (4,12%). </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Relevance</title><p>Relevance. Tomato considered a significant vegetable crop that plays a prominent role in the field of human health. At present, there are large numbers of tomato cultivars with a wide range of morphological and sensorial characteristics which determine their use. Farmers often use some chemical substances which have similar structure and activity with endogenous plant hormone called (exogenous) as a low-cost alternative to regulate plant growth and increase yield. Thus, the use of Plant Growth Regulators (PGRs) has become an important component of the agro-technical procedures for most cultivated species.</p></sec><sec><title>Methods</title><p>Methods. This study aims to evaluate the effect of four growth regulators (Krezacin, Chitosan, Zircon and Energene) on growth, productivity and quality of two Russian tomato varieties (Moriana and Superjol) under delta Volga conditions. Each type applied three times on both cultivars (Soaking tomato seeds before sowing, spraying on plants at vegetative phase, spraying on plants at flowering phase with three replications.</p></sec><sec><title>Results</title><p>Results. The results showed that; combination between Energene and cultivar Moriana enhanced the most of studied characters (Germination – 83.1%, fresh weight of Arial parts – 241.9 g, dry weight – 74.4 g, Number of № flowers/plant – 51.0, № fruits /plant – 35.6, fruit set – 69.8%, plant yield – 2.44 kg, TSS – 5.1°Brix, Content of Ascorbic Acid – 25.6 mg/100 g); Interaction between “Energene x Superjol” gave the maximum value for Plant height (85.6 cm), Fruit weight (72.6 g); while “Krezacin x Moriana” registered the highest fruit dry matter (6.77%) and Acidity (0.53%); Applying Zircon on Cultivar Moriana increased number of leaves/plant (56.8) and nitrate contents (27.6 mg/kg); the maximum LAI (150.1 cm2 ) obtained from interaction between Chitosan and cultivar Superjol whereas, “Chitosan x Moriana” treatment gave the highest level of Carotenoids (4.12%). </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>сорта</kwd><kwd>томат</kwd><kwd>регуляторы роста</kwd><kwd>высота растений</kwd><kwd>аскорбиновая кислота</kwd></kwd-group><kwd-group xml:lang="en"><kwd>tomato cultivars</kwd><kwd>Growth regulators</kwd><kwd>Plant height</kwd><kwd>Ascorbic Acid</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">Archer MC.
