To control the dispersal of invasive species and reduce the damage from the introduction of undesirable plants into the natural plant communities, it is necessary, first of all, to conduct an inventory of the alien flora fraction and investigate the biomorphological features of alien plants. The purpose of the study is to determine the number of spontaneous populations and to identify the biological characteristics of Adenocaulon adhaerescens (Asteraceae) that are actively settling in the Moscow. The goals of the work are mapping A. adhaerescens in the Main Botanical Garden of the Russian Academy of Sciences (GBS RAS) and Shchukinsky Forest Park (Moscow), identifying the amplitude of variability of the generative organs of the plants and determining their seed productivity in order to predict further expansion into the secondary distribution range. Using the route method we revealed the number of A.adhaerescens generative individuals in both localities. Morphological features were investigated using a KEYENCE VHX-1000 digital electronic microscope. The total number of generative plants was 5891 in the territory of the Main Botanical Garden of the Russian Academy of Sciences, and up to 1500 plants in the Schukinsky forest park. Annually, 1.5 million seeds are formed in the GBS RAS, and 127 thousand seeds – in the Shchukinsky Forest Park. Considering the morphological features of the seeds, which possess glandular trichomes, capable of clinging to animals and humans, the possibility of the rapid dispersal of this alien species by the seeds is not excluded. This gives grounds to attribute this species as a potentially invasive plant and take measures to control its numbers.

Assessment Results

The paper presents results of multiyear work to create and study the collection of Paeonia L. species in the Central Siberian Botanical Garden of the Siberian Branch of the Russian Academy of Sciences (CSBG SB RAS) (Novosibirsk), which numbers 13 species of 4 botanical sections nowadays. All herbaceous species of the genus Paeonia, both geophytes and hemicryptophytes, have been safely wintered during 12 years without additional shelter. The study shows assessment results of prospects of the genus Paeonia species representatives. It gives recommendations on landscape design for Paeonia species selection.

This report presents the results of the initial stage of Magnolia acuminata introduction at the Botanical Garden-Institute of the Far Eastern Branch of the Russian Academy of Sciences (Vladivostok). In the conditions of the southern part of Primorskiy Kray, M. acuminata has shown sufficient winter hardiness, habitus retention, high shoot-forming ability, bloom ability. In this regard, our recommendation is to include M. acuminata in the range of ornamental tree used for landscaping and to spread its introduction tests in the Primorskiy Kray.

The paper deals with anatomical parameters of the leaf of two genus representatives Rhododendron L.: R. catawbiense Michx. and R. brachycarpum D. Don, cultivated under conditions of N.V. Tsitsin Main Botanical Garden of the Russian Academy of Sciences. The morpho-anatomical structure of the leaf, used in the diagnosis and taxonomy of species, is also a key indicator of its functional characteristics. It is no less important for studying the mechanisms of their adaptation during introduction into new growing conditions and allows to find ways to optimize the conditions of their life and cultivation. Introduction experience is a prerequisite for studying the adaptive potential of species and for developing methods for managing the growth and development of these plants. The paper provides a detailed ecological and geographical characteristics of natural growth areas of R. catawbiense (eastern part of North America), R. brachycarpum (Far East, Republic of Korea, Japan) and the introduction area of Moscow (North-Eastern Administrative District, N.V. Tsitsin Main Botanical Garden of the Russian Academy of Sciences). In this work, for the first time, a detailed anatomical and morphological analysis of the leaf structure of two genus representatives Rhododendron: R. catawbiense and R. brachycarpum was carried out, and diagnostic signs of changes in the parameters of the structure of leaves, formed in conditions different from the natural habitats of species, were revealed during their introduction into N.V. Tsitsin Main Botanical Garden of the Russian Academy of Sciences.
