2023
The paper presents the results of one of the research stages, namely, the general bioecological peculiarities and microstructural characteristics of the leaf of Rhododendron brachycarpum D.Don. ex G.Don., of East Asian origin, growing in the humid subtropics of Georgia, in particular, in the Batumi Botanical Garden. The authors actively conduct scientific research on the unexplored species of the rich collection of rhododendrons in the Batumi Botanical Garden collection. They have determined that Rhododendron brachycarpum is characterized by a rich content of biologically active substances. This led to the study of the issue presented in the paper because the knowledge of the bioecological and microstructural peculiarities of the plant is necessary for its practical use and accurate identification. Rhododendron brachycarpum goes through a full cycle of development, well adapted to local environmental conditions. The morphological characteristics are consistent with the description in the scientific literature. The quality of seed germination is relatively low, however, it can be propagated by stem cuttings. The microstructure of the important raw material – the leaf, including the main midrib of the leaf, the leaf epidermis, and the leaf mesophyll have been studied.
