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.

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.
