“…Studies were conducted using semi-stationary methods (Childibayeva et al, 2022). Under field conditions, we described the identified populations with H. theinum and H. neglectum, established floristic composition (Kubentayev et al, 2021), abundance according to Drude (Sumbembayev et al, 2022), collected herbarium and collected samples of above-and below-ground plants for further anatomical and phytochemical. Latin names of plants are given according to POWO (2019), and the phylogenetic plant classification system is indicated according to Takhtajan (2009).…”

Hedysarum L. is one of the large genus of the Fabaceae Lindl. family, consisting of 200 species. Species in the genus Hedysarum are valuable forage and medicinal resources. In this study, we studied Hedysarum theinum Krasnob and Hedysarum neglectum Ledeb growing in the western Altai of Eastern Kazakhstan. H. theinum is a perennial, herbaceous, valuable medicinal plant, a rare species, an Altai-Dzungarian endemic, and a globally endangered species. H. neglectum is a perennial plant of high medicinal and fodder value, growing mainly in the sub-alpine zone. The purpose of the work is to identify the anatomical features and determine the phytochemical composition of the components of two species of Hedysarum. Route-reconnoitering methods were used in a field search of two species of Hedysarum for comparative study in 2020-2021. The extracts were analyzed by gas chromatography with mass spectrometric detection. The location of biologically active substances in the anatomical structure of the stem has been established. Biologically active substances are concentrated around the conductive bundles of the leaf and stem. The comparative anatomical structure of the stem in H. theinum revealed a thick ring of sclerenchyma under the cambium, which is absent in H. neglectum. In determining the phytochemical compounds of the aboveground organs of two Hedysarum species, the total number of components was 74, of which 55 compounds were found in H. theinum and 57 in H. neglectum. In both species, 37 components were detected, in H. neglectum 11 components had significant content, in H. theinum 9 components contained a significant percentage of compounds. Analysis of the root extract showed that H. theinum contains 27 and H. neglectum contains 29 compounds. Of these, 15 compounds are characteristic of both species. The phytochemical data obtained confirm the anti-inflammatory, antibacterial, antifungal, antimicrobial, antimalarial, and antitumor properties of these plants.

“…On the contrary, in Eastern Kazakhstan, the main limiting factors are a short frost-free period, recurrent spring frosts and low winter temperatures. Therefore, winter hardiness and frost resistance are the dominant indicators of the prospects for introduction [24][25][26].…”

This study, conducted with meticulous attention to detail, comprehensively examines the state of plants and their adaptation to Kazakhstan's extra-arid climatic zone of the Mangistau. It uses the collections of woody plants from the Mangyshlak Experimental Botanical Garden in Aktau as a case study and extrapolates the results to the entire region. The study area is arid and unsuitable for many plants, so examining physiological adaptation mechanisms and strategies for preserving plants in unfavourable conditions is crucial. The study employed a range of methods, including the measurement of the intensity of transpiration, leaf hydration, and the content of chlorophyll A, B, and carotenoids. These methods were chosen for their proven effectiveness in similar studies and their ability to provide accurate and reliable data. The samples were also assessed using a point system for resistance to drought, phytophagy, gas tolerance, salt tolerance, winter hardiness, and soil fertility. The results obtained and entered into the IEBG platform “DinTseR” to assess the value of the introduction using a diagnostic scale revealed a high variability (up to 51.7-52.2%) of physiological indicators of growth and development. The highest values of transpiration intensity were observed in deciduous trees and shrubs, rose varieties (205-243 mg/g fresh leaf mass per hour), leaf water content - in climbing plants (68.9%), chlorophyll A and B content - in deciduous plants, and plants - old trees, fruit trees and varietal roses (3.46-3.93 and 1.34-1.84%). Their concentration in coniferous species is almost two times lower (0.63%). A correlation was also made between various significant factors. Twenty regression equations and forecasts have been identified that can be used to diagnose and assess resistance, thereby reducing the cost of determining the introduction value in the conditions of Mangistau. These findings are essential in understanding and preserving the unique flora of the Mangistau region.

“…At the same time, a limited number of studies have been conducted on the study of Rheum species at the population level (Libert and Englund 1989;Song et al 2015;Khan et al 2019), especially in Kazakhstan (Dagarova et al 2017)being a peripheral part of the range. Morphometry of generative organs (Eshibaev et al 2021;Sumbembayev et al 2021;Aidarkhanova et al 2022;Orazov et al 2022;Sumbembayev et al 2022;Vesselova et al 2022) and seeds, in particular, can serve as a qualitative systematic trait. According to the analysis of carpological studies (Zhao et al 2008;Sharma and Sharma 2017;Kong et al 2018;Tan et al 2019; Bhardwaj and Sood 2020), rhubarb fruits and seeds have differences that, together with other diagnostic features, can be used to clarify systematic relationships and determine species.…”

Abstract. Sumbembayev AA, Lagus OA, Nowak S. 2023. Seed morphometry of Rheum L. (Polygonaceae) species from Kazakhstan and its implications in taxonomy and species identification. Biodiversitas 24: 4677-4692. In the article, the evaluation of morphometric and weight parameters of seeds of 7 species of the genus Rheum L. from Kazakhstan is presented, as well as an analysis of their biometric parameters from different ecological and geographical habitats. The purpose of the study was to determine the variability of the seeds of the studied taxa and the importance of the results in determining the taxonomic relationships within the genus. The external structure was described for all species of the genus. Seeds of all studied species are illustrated with photos and scale drawings, and their features are summarized in a table. Stable and taxonomically significant features were identified for the species of the section Ribesiformia, represented by R. cordatum and R. maximowiczii, allowing their identification. The correlation between seed metric parameters and environmental conditions of the site and growth area was established and found a significant relationship between morphometric data and most of the environmental factors studied. The low adaptive potential of rhubarb species in Kazakhstan and the species' narrow ecological range were found. The comparison of the results obtained with the taxonomic relationships and phylogeny of representatives of the genus are briefly discussed.
