Abstract

According to the results of the primary introduction, based on the study of adaptability indicators in cultural conditions, the studied rare and endangered species of the flora of East Kazakhstan are ranked according to three categories proposed by K. A. Sobolevskaya. The 1^st category includes 45 species of rare and endangered plants that reacted positively to the conditions of culture. The second category includes 16 species that gave contradictory results of introduction due to insufficient knowledge. The third category consists of 9 highly specialized species that have given a negative result during introduction, which can be preserved only in natural habitats. When studying the adaptive potential in culture of two rare species of orchids - Dactylorhiza incarnata ( L.) Soo and Dactylorhiza maculata (L.) Soo, attracted to the primary introduction from the Kalbinsky Altai, according to the results of phenological observations, instability in the seasonal rhythms of species development associated with the weather conditions of the growing season of 2021 was revealed. When comparing morphometric indicators of D. incarnata and D. maculatа samples in natural cenopopulations and during introduction for 2019-2020, no differences were established.
