Geobotanical characteristics of plant communities with participation of rare species Alnus glutinosa (L.) Gaertn.

The article gives a geobotanical description and a floristic analysis of communities with the participation of the rare and relict species Alnus glutinosa in condition of Aktobe region. The aim of the study is to provide a geobotanical assessment of the current status of a rare, relict species of the Alnus glutinosa population, which was included in the Red Data Book of Kazakhstan. At present, the flora of the Aktobe region is not sufficiently studied.

Comparison of fatty acids and amino acids profiles of the selected perennial and annual wheat varieties from Kazakhstan.

This study applied various chromatographic methods to assess the chemical composition of five selected perennial and annual wheat seed varieties cultivated in Kazakhstan. Gas Chromatography (GC) analysis revealed distinct fatty acid profiles, with perennial, soft, and durum annual wheat seeds displaying varying levels of saturated fatty acids (SFA), monounsaturated fatty acids (MUFA), and polyunsaturated fatty acids (PUFA) (SFA: 10.538 - 19.

Evaluation of the Chemistry, Antioxidant and Cytotoxic Activity.

Background: The family includes the medicinal herb Willd. The aerial and underground parts of plant were studied for their chemical composition, antioxidant, and cytotoxic properties.

Methods: Using gas chromatography with mass spectrometric detection (7890A/5975C), 94 chemicals were identified in ethanol extract from leaves, roots, seeds, and stems of .

Current state of populations of Rhodiola rosea L. (Crassulaceae) in East Kazakhstan.

Background: Based on world experience, first, a modern assessment of the flora is needed to develop strategies for the conservation of ecosystems of rare and endangered plant species. A regional and global biodiversity strategy should focus on assessing the current state of bioresources. To preserve the biodiversity of the species and its habitat, we evaluated botanical features, ontogenetic phases, the ecological and phytocenotic structure of the rare and endangered of Rhodiola rosea L.

Influence of new sulfur-containing fertilizers on performance of wheat yield.

Wheat is the main cereal crop in Kazakhstan and fertilizers play an important role in enhancing harvest growth. In this study, the impact of new sulfur-containing fertilizers on the growth and yield of wheat was evaluated, and the resistance of varieties to Erikss was also investigated. (also known as Rob.

The Influence of Abiotic Stress Factors on the Morphophysiological and Phytochemical Aspects of the Acclimation of the Plant Boriss.

Plants of the family are natural accumulators of many medicinal secondary metabolites (SM). This article describes the study of morphophysiological, anatomic and phytochemical responses of immature plants of under water deficit and (or) cold-stress conditions. Changes in biomass production due to water content in plant tissues such as a decrease in water deficit and an increase in cold stress were revealed.

Effect of sulfur-containing agrochemicals on growth, yield, and protein content of soybeans (Glycine max (L.) Merr).

In this study, effect of different forms of sulfur-containing agrochemicals on growth, yield, and protein content of soybean grains have been evaluated. Three forms were used, such as powdery, solute, and pasty, in which elemental sulfur is contained in a nanostructured state. Plants treated with powdered and solute sulfur-containing agrochemicals had the highest growth and grain yield values, and the effect of applying pasty sulfur-containing agrochemicals did not differ from the control, in which there was low yield on all variants.
