Abstract:
This article presents the research on the deterioration of soil properties under the influence of wind erosion in the "Todakol massivi" in the northern part of Qorovulbazar district of Bukhara region. In particular, the effects of natural stress factors on the growth and development of pasture plants such as white haloxylon (Haloxylon persicum L.), black haloxylon (Haloxylon aphyllum L.), sagebrush (Artemisia tenuisecta L.), tamarisk (Tamarix hispida L.), harmel (Peganum harmala L.), seta (Salsola sclerantha L.), alhagi (Alhagi sparsifolia L.), sagebrush (Salsola arbuscula L.), black redroot pigweed (Amaranthus retroflexuss L.), sedges (Carex physodes L.), downy brome (Bmomus tectorum L.), barley (Eremopyrum Orientale L.), salty crabgrass (Aeluropus litoralis L.), alhagi (Alhagi psudoalhagi L.), which are widespread in the region, are highlighted. In particular, soil erosion due to the wind in the area and the amount of easily soluble salts in water were determined and analyzed.

Abstract:
Microscopic fungi are microorganisms commonly found in grain crops. They typically reproduce asexually with the formation of spores of various types. Most species also have sexual reproduction, but many mushrooms can exist without it for several generations. Spores of microscopic fungi can remain viable for a long time in dry and cold environments. Spores are spread passively by wind and rain, and insects can also serve as a transmission factor by carrying spores on their bodies. Insects increase the growth surface for mold fungi, breaking the outer protective shells of grains. In the presence of sufficient conditions for growth (temperature, humidity, etc.), micromycetes can reduce the nutritional value of grain products and release metabolites in food raw materials that have toxic properties even in low quantities, as well as lead to a deterioration in the technological value of grain. The purpose of this study was to determine the level of contamination of winter wheat by pathogenic and saprotrophic fungi in the Rostov region in the period 2015–2021. In the studied samples, the presence of external infection was noted up to 75.4 %, internal infection – up to 54.6 %, which indicates high contamination during the growing season and harvesting of the grain crop. The scale of the average annual values of the proportion of samples infected with F. moniliforme over a seven-year period was 58–95 % for external infection, and 31–86 % for internal infection. There was a dominance of external infection over internal infection by 20.8 %. In field agrocenoses, F. moniliforme is a pathogen of many crops, especially corn, wheat, and barley, causing the development of rot, vascular diseases, and toxicosis. The main mycotoxins produced by this species are fumonisins; beauvericin, fusaric acid and fusarin were also found among the metabolites of individual strains of the fungus.

Abstract:
In this article, we propose to use real-time correlation-spectral analysis systems (developed in FEB RAS) to identify morphometric classes of plant roots and consider this solution as a full-fledged alternative to outdated analog laser/optical diffractometry and laser Fourier technology with the calculation of Lendaris parameters/indices and the construction of projection transformants. The proposed technique can be implemented using a PC, laptop or tablet with older operating systems. Simplicity and low cost make this technique accessible to users from the agricultural industry who are not specialists in the field of optics or laser physics. In this article, we tried, in clear language, without resorting to formulas, to explain to botanists and agricultural specialists what, in essence, the method under consideration is, what advantages it brings to practicing botanists and what information can be extracted using it (not excluding the description of artifacts and errors, which can lead to disappointment in the method, which is based on an error rather than the incorrectness of the proposed method). The second part of the article provides an atlas catalog of Fourier spectra and microphotographic images of corresponding botanical forms and structures.
