The article provides information on the activity of peroxidase enzyme in the composition of the seeds and bark of some varieties of soy cultivated in Uzbekistan and the importance of this enzyme in plant life. As is known, soybeans are one of the main nutritional plants of Agriculture. Orzu and Vilana varieties are resistant to other varieties, and the main thing is that they can be planted in crop fields in all regions of the republic, achieve high fertility and thereby satisfy the demand of the population for feed products.

The article studies the activity of the peroxidase enzyme in cereals and barks of some varieties of soy plants. The soy (plant) samples we studied were obtained in the conditions of the Tashkent region at the experimental field of the institute of genetics and plant experimental biology in the village of Durmen. 11 samples out of 40 examined on electrophoregrams did not show the presence of the studied enzymes. Further research is needed to clarify the results.

The article is based on the use of experimental polyploidy method, with the introduction of new introgressive hybrid forms combining several species genotype with pathogenic Verticillium dahliae Kleb. and the effects of mycotoxins separated from the Fusarium oxysporum ***. vasinfectum micromicette on the yield of plant seeds. New artificial complex hypertension forms based on experimental polyploidy Verticillium dahliae Kleb. and Fusarium oxysporum ***. vasinfectum combine the potential of resistance to mycotoxins separated from microcrystals, making a tremendous contribution to the selection of new varieties and to the effectiveness of selection as a result of the use of genetic selective research as genetic-selective genetic-selector studies.

This article deals with the biochemical characteristics of varieties of Saint Mary’s Thistle such as Panacea, Debut and Samaryanka. Based on the studies, it was found that the highest oil content was found in the species Debut (26%). The lowest oil content was observed in the variety Samaryanka (19%). The highest protein content and the sum of total amino acids in the seeds of St. Mary’s Thistle varieties were found in the variety Debut (131.1), and the lowest indication was observed in the species Samaryanka (79.2). By the number of replaceable amino acids existing in the seeds of the species of St. Mary’s Thistle, it was found in the Varieties Debut (126.3), and the lowest indication was observed in the variety Samaryanka (112). Based on the results of studies and the noted biochemical characteristics and varietal differences of the St. Mary’s Thistle, the possibility and expediency of expanding the crops of this species in the soil and climatic conditions of the Khorezm region are suggested. The research was conducted 2017-2019 y.

Cassava （Manihot esculenta Crantz） sheds its leaves during growth, especially within the tropical dry season. With the production of SAG12-1PT transgenic cassava we want to test the level of leaf retention and altered cytokinin metabolism of transgenic plants via the autoregulatory senescence inhibition system. After confirmation of transgene expression by molecular analysis and phenotype examination in greenhouse plants, two transgenic plant lines, 529-28 and 529-48, were chosen for further investigation. Detached mature leaves of 529-28 plants retained high levels of chlorophyll compared with wild-type leaves after dark-induced senescence treatment. Line 529-28 showed significant drought tolerance as indicated by stay-green capacity after drought stress treatment. Field experiments proved that leaf senescence syndrome was significantly delayed in 529-28 plants in comparison with wild-type and 529-48 plants. Physiological and agronomical characterizations of these plants also revealed that the induced expression of IPT had effects on photosynthesis, sugar allocation and nitrogen partitioning. Importantly, the 529-28 plants accumulated a high level of trans-zeatin-type cytokinins particularly of corresponding storage O-glucosides to maintain cytokinin homeostasis. Our study proves the feasibility of prolonging the leaf life of woody cassava and also sheds light on the control of cytokinin homeostasis in cassava leaves.
