The purpose of our research was studying the indicators of grain quality, productivity and analysis of anatomical stem structure during the full maturity of two cultivars of winter common wheat.Novelty of work consists in carrying out such a research using a local standard cultivar Almaly and a new cultivar SWW 2/127 grown using the drip irrigation technology.Researches were carried out in field and laboratory conditions using methods of field experiment, drip irrigation, microscopic section and biometric analysis.Stem structure of the 3rd internode, epidermis thickness, length and width of large conducting bundles, xylem length and width, thickness of parenchyma cell and culm thickness were analyzed.SWW 2/127 cultivar demonstrated increase of the values of these traits.Other biometric indicators of SWW 2/127 cultivar such as thickness of mechanical tissue and bark, length and width of small conducting bundles demonstrated their decreasing in comparison with Almaly cultivar.Some increasing of the total quantity of small conducting bundles of the primary bark of Almaly cultivar was noted in comparison with SWW 2/127 cultivar; and vice versa decreasing of the total quantity of large conducting bundles of Almaly cultivar was observed in comparison with SWW 2/127 cultivar.Almaly cultivar had higher rates of mass of 1000 grains (51.7 g), grain nature (772 g L -1 ), glassiness (85%), protein quantity (15.6%) and gluten quantity (34.4%).Both cultivars formed grain nature, glassiness, starch and protein quantity, gluten quantity at the level of State standards for strong and valuable wheat; gluten quality corresponded to the 2nd group.Indicators of the ear structure of Almaly cultivar were higher than indicators of SWW 2/127 cultivar.Productivity of Almaly cultivar was 91.8 centners per a hectare, seed sowing norm was 2 million grains per a hectare; productivity of SWW 2/127 cultivar at the same norm of seed sowing was 77.4 centners per a hectare.

In this study, the morphological, anatomical features, chlorogenic acid content and antioxidant activities of two species from the genus Xanthium, namely Xanthium spinosum L. growing in the slopes of Mount Daubaba in the western part of the Talas Alatau of Tyulkibas region of the South Kazakhstan region and Xanthium strumarium L. growing in the slopes of the Alma-Arasan gorge of the Trans-Ili Alatau, Almaty region, were investigated.Xanthium strumarium L. is a one-year-old widespread plant.Height is 20-100 cm, leaves are straight, pubescent, thinly faceted.On the surface of the stem there are greyish-green or browngreen spots.Xanthium spinosum L. -height is 25-100 cm.Difference of stems from species Xanthium strumarium L. is thickly branched, creeping, low-directed small solid hairs.The main and lateral roots of the plant are well developed.The anatomical structure of the transverse cut of the root of species of the genus Xanthium L. is rounded.The epidermis is completely preserved.In the anatomical structure of the stem the epidermis of the stem is well developed in species Xanthium L. The central cylinder is closed collateral, the single conducting beams are arranged ring-shaped.The leaf plate of the species Xanthium L. consists of loose mesophilic and stem tissues.Conductive beams are well formed in the central system.Besides, a simple, precise, repeatable and accurate HPLC method for determination of chlorogenic acid in samples from the genus Xanthium was developed and validated.It is also observed that the extracts obtained from the leaves or stems of these plants have significant antioxidant activity, which correlated well with chlorogenic acid content of these samples, indicating that chlorogenic acid could be important contributor of antioxidant capacities of species of the genus Xanthium L.
