The study reports results of research carried out from April to October during 1988–2016 at the Botanical Garden of Petrozavodsk State University (South Karelia, middle taiga subzones). Three introduced species of the genus Larix (Larix sibirica Ledeb., L. leptolepis (Sieb. et Zucc.) Gord, and L. dahurica Turcz. ex Trautv.) were studied. The growth of shoots and needles in different species begins, reaches its culmination, and ends almost simultaneously, differing by no more than one week across the species. L. sibirica shows the highest growth rate. The timing of growth, culmination, and the dynamics of growth of shoots and needles are largely determined by variations in precipitation, temperature, and humidity. The direction and strength of such an effect may vary from year to year. The dates of phenological phases of the Larix species studied here are chiefly determined by the air temperature in the current growing season and the dates of formation of wintering buds in the previous growing season. Bud swelling and opening begins almost simultaneously in the studied species. Most of the other phenological phases begin and end earliest in L. sibirica and latest in L. leptolepis. All the studied species, primarily L. sibirica, are promising for residential landscaping and creation of artificial plant communities in Karelia

Among fruit crops, Rowan is one of the most winter-hardy. In Russia, the predominant varieties are those derived from Sorbus aucuparia. Rowan fruits are used in fresh and dried form, they are valuable in food, dietary, and medicinal terms. The objects of this study were 7 Rowan varieties in the exposition «Wild fruit plants» of the Botanical garden-Institute of Volga State University of Technology (Yoshkar-Ola, Mari El Republic). The research was conducted in 2014–2019. The fruits were collected in the mass maturation phase and weighed in 3 samples of 100 pieces. The yield of air-dry fruits, expressed as a percentage, was obtained by the ratio of the mass of dried fruits to the mass of freshly harvested ones. It was found that the varieties ‘Alaya Krupnaya’, ‘Titan’, ‘Granatnaya’, and ‘Burka’ are characterized by large fruits. ‘Desertnaya Michurina’, ‘Nevezhinskaya’, and ‘Doch Kubovoy’ are small-fruited varieties. The most favorable for fruiting of most varieties were 2016 and 2019 with dry conditions of the growing season. Excessively moistened conditions in 2017 negatively affected the formation of Rowan fruits. The yield of air-dry raw materials was inversely correlated with the weight of fruits. The obtained data can be used in the organization of plantation cultivation of Rowan varieties in the conditions of the Volga-Vyatka region.

Интродукция как одна из традиционных в лесном хозяйстве сфер практической деятельности сохраняет свою актуальность и на современном этапе. Обладая широким спектром полезных признаков и свойств, представители рода берёза (Betula L.) подвергаются разноплановым исследованиям. Цель данного исследования являлось получение сравнительной оценки различных видов, входящих в таксономическую систему рода берёза, по степени лигнификации ксилемы. Объектом исследования служили посадки 10 видов берёзы, представленных в интродукционной коллекции ботанического сада Нижегородского государственного университета им. Н.И. Лобачевского. Предметом исследования являлась изменчивость степени лигнификации ксилемы у интродуцированных и аборигенного видов берёзы. Первичной единицей выборки в опыте принят однократный учет временных препаратов поперечных срезов из средней части годичного прироста, которые после окрашивания и фиксации визировали с помощью микроскопа Микмед-2. Одревеснение клетчатки в стенках клеток ксилемы выявляли с помощью качественной реакции флороглюцина на лигнин. Дополнительно был произведен опытный анализ сроков опадания листвы у исследуемых объектов. В ходе анализа степени лигнификации клеток ксилемы в годичных побегах видов берёзы, в пределах опытного участка, установлена их неоднородность по значениям изучаемых показателей вне зависимости от видовой принадлежности. Минимальное число неодревесневших клеток ксилемы свидетельствовало о большей степени подготовленности растений к неблагоприятному зимнему периоду и более раннему опаданию листвы. Различия проявились на выровненном экологическом фоне в условиях Нижегородской области и подтверждены результатами однофакторного и двухфакторного дисперсионного анализа. Introduction as one of the traditional areas of practical activity in forestry remains relevant at the present stage. Having a wide range of useful features and properties, representatives of the genus birch (Betula L.) are subject to diverse research. The purpose of this study was to obtain a comparative assessment of various species included in the taxonomic system of the genus birch, according to the degree of lignification of xylem. The object of the study was the planting of 10 species of birch presented in the introduction collection of the Botanical garden of Nizhny Novgorod state University. N.I. Lobachevsky. The subject of the study was the variability of the degree of xylem lignification in introduced and native birch species. The primary sampling unit in the experiment was a one-time recording of temporary preparations of cross-sections from the average part of the annual growth, which, after staining and fixation, were viewed using a Micmed-2 microscope. Lignification of fiber in the walls of xylem cells was detected using a qualitative reaction of phloroglucin to lignin. Additionally, an experimental analysis of the timing of leaf fall in the studied objects was performed. During the analysis of the degree of lignification of xylem cells in annual shoots of birch species within the experimental area, their heterogeneity in the values of the studied indicators was established, regardless of the species. The minimal number of non-woody xylem cells indicated that the plants were more prepared for the unfavorable winter period and earlier leaf fall. The differences were revealed against a leveled environmental background in the Nizhny Novgorod region and were confirmed by the results of one-factor and two-factor analysis of variance.

The results of a long-term introduction study of Hungarian lilac, an endemic of the Carpathians and Transylvania, cultivated in the South Ural Botanical Garden-Institute of the UFIC RAS, are presented. The study used phenological data from 2005-2020. The beginning of the growing season for Hungarian lilacs falls on the period from April 14 to 30, flowering is observed annually in late May and early June. The duration of flowering over the last 5 years (2015-2020) averaged 16 days, which is 6 days shorter than the flowering period of this type of lilac in 2005-2009. The likely reason for the shortened flowering period is climate change. Complete lignification of the shoots of Hungarian lilac occurs in the second half of July. In Ufa, Hungarian lilacs have fruiting (seeds begin to ripen from September 18 to 27), as well as the presence of self-seeding. The beginning of leaf fall (the end of the growing season) coincides in timing with the beginning of seed ripening. All phenological phases of Hungarian lilac retain their sequence every year. Winter hardiness is usually I point (plants are absolutely winter hardy). The phenological atypicality index is -0.250 or 4 points according to Zaitsev, which means that the phenology of the species is fully consistent with the climatic conditions of Ufa. Thus, the introduction of Hungarian lilac in the South Ural can be characterized as successful and promising.

Wild Strawberries

Abstract. The productivity of wild strawberries is significantly determined not only by the biological characteristics of the variety and soil and climatic conditions, but also by agrotechnical techniques and the use of organomineral fertilizers. The effectiveness of the use of mineral fertilizers on strawberries has been proven by numerous studies [5, p. 48; 6, p. 99; 14, p. 233; 15, p. 513; 16, p.101; 17, p. 513]. The purpose is a comparative assessment of the effect of various types of complex fertilizers for strawberries. The task was to study the effect of complex fertilizers on the yield of strawberry and its structure. In 2015–2018, studies were conducted on the introduction of complex fertilizers for wild strawberries, which are used during the growing season to improve their nutrition during periods of maximum consumption of nutrients. Methods. The studies were conducted according to generally accepted methods [4], [7]. The influence of “Azophoska”, “Perm-yagodnoye” and “Fasko-yagodnoye” fertilizers on the yield and elements of its structure in strawberry was studied in the conducted studies. Results. The best results for all the years of research were obtained when using the pre-planting application of the fertilizer “Fasko-yagodnoye”. In this variant, there was a significant increase in the number of berries by 1.8 pcs., their weight by 0.68 g and yield by 0.13 kg/m2. Scientific novelty. For the first time in the conditions of the Udmurt Republic, the effect of the pre-planting application of complex fertilizers “Perm-yagodnoye” and “Fasko-yagodnoye” was studied on strawberry garden. Practical significance. The obtained research results are of great practical value, since it is proved that the productivity of wild strawberries in the Udmurt Republic increases with the use of complex fertilizers.
