Malus sieversii is a mountain-steppe and valley tree species widespread in the mountains of southeast Kazakhstan. The aim of this work is to study the structure of variability and intraspecific differentiation of Malus sieversii (Ledeb.) M. Roem. based on a complex of morphological features of generative organs and the characteristics of the seasonal rhythm of apple trees in natural and introduction conditions. Malus sieversii is a mountain-steppe and valley tree species widespread in the mountains of southeast Kazakhstan. The introduction collection of Malus sieversii’s forms growing in the Main Botanical Garden of Almaty (GBS) is a source of global genetic resources. According to the research data, the intraspecific variability of the studied apple tree forms was characterized by heterogeneous morphometric parameters of the generative organs. The studied apple trees are distinguished by heterogeneous morphometric parameters. Large-flowered forms were observed both in natural populations and in GBS. In the conditions of the Dzungarian Alatau, the large sizes of flowers were characteristic of the forms in the gorges of Pikhtovaya and Mushabay. Among the variety clones the sample TP-19 selected in the Pikhtovaya distinguished itself by the large size of the corollas.

This article presents the results of a comprehensive assessment of the ecological status of populations of the rare endemic species Schmalhausenia nidulans native to the high-mountain regions of the Northern Tien Shan. The aim of the study was to investigate the current state of the species populations by analyzing their numbers, ontogenetic structure, morphometric parameters, and anatomical features. Two natural populations of the species were examined: the first population, located on the Uzynkara Ridge at an altitude of 3003 m above sea level, and the second population, growing on the Ile-Alatau Ridge at an altitude of 3260 m above sea level. During the field research, the population size, age structure, and morphological traits of individuals at the juvenile, immature, virginal, and generative stages of development were studied, and an anatomical analysis of the stem structure was also conducted.
