The influence of spectral composition of UV-light
on growth and activity of endogenous phytohormones
in wheat seedlings
This article provide experimental information on the influence of presowing UV-irradiation of seeds on growth and the activity of endogenous phyohormones in seedlings of two varieties of wheat. It suggests that UV-irradiation of seeds in the field of 254 nm depresses the wheat seedlings growth and increases in activity of abscisic acid, while UV-irradiation of seeds in the field of 313 and 365 nm stimulates seedlings growth and increase in auxins activity.
Ключевые слова: UV-irradiation; seeds; wheat; growth; phytohormones.

Morphological signs of perspective wheat lines in rein field conditions in Central Tajikistan
In this article presents the results of study to determine the yield and biochemical composition of grain lines of mapped forms of wheat in rain field conditions. It was shown that the yield of all studied wheat lines was 3-4 times higher than that of the Lalmicor variety and 2.0-2.7 times than that of the Orien variety. The highest protein content was found in the seeds of lines ITMI 77 and ITMI 6. The starch content, promising mapped wheat lines prevailed over the standard variety Zafar. In general, the lines ITMI 6, ITMI 43, ITMI 45, ITMI 49, ITMI 55 and ITMI 77 can be recommended for growing in rain field conditions.

Evaluation of the efficiency of micropropagation of some raisin grape varieties in in vitro culture
The research was carried out in the period of 2014 to 2017 in the Center of biotechnology of the Tajik National University. For the first time in Tajikistan, an assessment of the effectiveness of micropropagation of raisin grape varieties growing in the country was carried out.
The different regenerative capacity in in vitro culture was noted at the stage of micropropagation of explants of the studied grape varieties during four passages. An even increase in the average value of the multiplication coefficient over passages of eleven seedless grape varieties is observed from the first to the fourth passage (from 1.5 in the first passage to 3.3 in the fourth). The average value of the multiplication coefficient for the four types of investigated explants by passages is practically the same.
Ключевые слова: grapes; microshoots; micropropagation coefficient; effectiveness; passage; Tajikistan.

Productivity of rotary corn depending on the degree of water security of the crops in the conditions
of the Gissar valley
The article presents the results of a study of the influence of the irrigation regime on the yield of stubble corn. It was found that under the conditions of the Gissar valley, it is necessary to carry out 9 irrigations according to the scheme 6-3 with an irrigation rate of 5401 m/ha, which at an irrigation rate of 600 m/ha ensures the maintenance of soil moisture at the level of 80%, an increase in the yield of green mass by 301.2 c/ha. and a 42% decrease in the unit costs of irrigation water per 1 centner of green mass of corn in relation to irrigation carried out in production conditions.
Ключевые слова: stubble corn; yield; moisture availability; pre-irrigation soil moisture; water consumption; irrigation regimes; terms and rates of irrigation.
Microflora offin - fiber cotton rizoplane in the conditions Khatlon regions
Studies have shown that with the simultaneous infection of the tissues of root system of fine - fiber cotton with the pathogens of Fusarium black root rot and bacteria, a weakening of the manifestation of the disease is noted which becomes especially noticeable as bacteria spread in the endotissues coincides with the phrase of budding and is expressed in the absence of external symptoms of the manifestation of Fusarium wilt of black root rot.

The role of mineral fertilizers in increasing
the productivity of soybean and mung bean
The article describes the role of mineral fertilizers in increasing the productivity of soybean and mung bean in the conditions of Northern Tajikistan. And also the results of the influence of mineral fertilizers on the leaf area, FP, PPF, content, consumption, removal and productivity of soybean and mung bean plants have been proven. In experiments, the use of mineral nitrogen fertilizers significantly influenced the grows and intensity of development of soybean and mung bean, which contributed to an increase in their yield. So, depending on the studied variants of the experiment, the yield of soybean grain ranged from 15.8-27.6 c/ha and mung bean from 13.0-24.1 c/ha.
