Сравнительно-палиноморфологическое исследование естественно произрастающих и интродуцированных представителей лапин позволит выявить таксономическое значение морфологических признаков пыльцы рода и особенности пыльцы культивируемых растений. Охарактеризованы качество пыльцевого материала и интродукционный потенциал растений из Ботанического сада БИН РАН.Материалы и методы. Пыльцевые зерна изучены с помощью светового, конфокального лазерного сканирующего и сканирующего электронного микроскопов. Фертильность определяли стандартным ацетокарминовым методом.Результаты. Впервые проведено сравнение морфологии пыльцы культивируемых и обитающих в естественных условиях растений этого рода. Фертильность пыльцевых зерен у всех изученных образцов, за исключением Pterocarya fraxinifolia (Lam.) Spach, очень высокая, в основном более 90%. Фертильность зерен P. fraxinifolia в разные годы варьирует от 28 до 73%, что является низким или средним показателем качества пыльцы. В результате изучения 12 образцов выявлено, что пыльцевые зерна пяти таксонов сплющенные, средних размеров, 21–45 мкм в диаметре, 4–8-поровые, поры расположены вблизи экватора. Скульптура микрошипиковатая. У P. fraxinifolia обнаружены мелкие пыльцевые зерна, а также зерна с бугорчатой поверхностью, в нераспавшихся тетрадах и диадах. Приведены данные об интродукции рода в Санкт-Петербурге.Заключение. Палинономофологическая характеристика является диагностической для рода Pterocarya Kunth. Пыльца птерокарий хорошо отличима от других ветроопыляемых таксонов, однако точные определения видов по пыльце с целью спорово-пыльцевого анализа невозможны. Морфологически наиболее разнообразны зерна низкофертильного образца P. fraxinifolia. Ограниченная возможность семенного размножения P. fraxinifolia, вероятно, связана с низкой фертильностью пыльцы у интродуцированного экземпляра. Качество пыльцы произрастающих в культуре P. rhoifolia Siebold et Zucc. и P. stenoptera DC. высокое. </p></abstract><trans-abstract xml:lang="en"><p>Background. Comparative palynomorphological studies of naturally occurring and introduced Pterocarya Kunth representatives reveal the taxonomic significance of pollen morphological features and pollen characters of cultivated plants. The quality of pollen material and the potential of the plants from the Botanical Garden of BIN RAS for introduction are characterized.Materials and methods. Pollen grains were investigated using light, confocal laser scanning and scanning electron microscopes. Fertility was assessed using the standard acetocarmine method.Results. Comparison of pollen morphology in cultivated and naturally growing plants of this genus was made for the first time. Pollen fertility of two cultivated species (Pterocarya rhoifolia Siebold et Zucc., and P. stenoptera DC.) was very high, generally over 90%. Fertility of P. fraxinifolia (Lam.) Spach grains varied from 28 to 73% in different years, which is a low or medium level of pollen quality. Morphologically, pollen grains of all 12 specimens from five taxa are flattened, medium sized, 21–45 μm in diameter, with 4–8 pores; pores are located mainly at or near the equator. The pores are round or oval, with a limbus. Exine is three-layered, thickened near the pore. The sculpture is microechinate. The low-fertile P. fraxinifolia specimen contains small pollen grains, as well as grains in tetrads and dyads. The data on the introduction of the genus in St. Petersburg are presented.Conclusion. The palynonomophological description is diagnostic for the genus Pterocarya. The Pterocarya pollen is well distinguishable from other wind-pollinated taxa; however, species identification by pollen for spore-pollen analysis is not practicable. Morphologically, the most diverse are the grains of the low fertile specimen P. fraxinifolia. The limited possibility of seed propagation of P. fraxinifolia is probably explained by low pollen fertility. The pollen quality of the introduced P. rhoifolia and P. stenoptera is high.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>спородерма</kwd><kwd>фертильность</kwd><kwd>лапина</kwd><kwd>репродукция</kwd><kwd>интродукция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>sporoderm</kwd><kwd>fertility</kwd><kwd>reproduction</kwd><kwd>introduction</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">работа выполнена с использованием дендроколлекции Ботанического сада Петра Великого БИН РАН и на оборудовании ЦКП «Клеточные и молекулярные технологии изучения растений и грибов» Ботанического института им.
