Formation and morphology of Rhus typhina L. inflorescence in conditions of the right bank forest steppe of Ukraine

Abstract

Peculiarities of growth and development of shoots of Rhus typhina L. in the conditions of the Right-bank forest-steppe of Ukraine are characterized. The morphological description of inflorescences and flowers of the species is carried out. The description took into account the stages of formation of the vegetative component of the inflorescence, the most significant features of its structure, the number of flowers in the inflorescence, and flowering dates. Pistillate and staminate flowers are collected in complex, botric, botanical, bractose, pyramidal inflorescences - panicles. The studied plants are characterized by acropetal type of inflorescence flowering. Abundance and level of flowering are estimated. In the research conditions generative individuals of R. typhina bloom annually. We estimated the abundance of R. typhina flowering in 4 points that corresponds to a high level.
