Ground Part

We have found out the effect of synthetic plant growth regulators – Azotofite, Vympel, Amber acid on assimilation processes of winter wheat sort Yuvivat in the autumn and spring periods.The formation of the assimilation surface for winter wheat plants is a decisive factor in increasing the productivity of the crop. It was ascertained that on the 12th day after the emergence of the stairs an increase in the assimilation surface of winter wheat under the influence of Vympel – by 7.8%, Amber acid – by 17.2%, Azotofite – by 20.3%.On spring period on 217 days after the emergence of the seedlings, an increase in the assimilation surface of winter wheat under the influence of Azotofite – by 40.2%, Vympel – by 32.2%, and Amber acid – by 22.8% compared to the control. Such an effect of Azotofite can be explained by the fact that it consists of cells of nitrogen-fixing bacteria Azotobacter chroococcum.In turn, Vympel, at the expense of humic acids in its composition, enhances root formation and improves nutrition, which helps to increase the growth of the above-ground part of plants.At 227 days after the appearance of the stairs, similar results were observed with the previous ones. The most effective was detected by Azotofite. He exceeded the control rate by 40.4%. The increase in the assimilation surface under the influence of Vympel was 33.1% compared with the control.The use of synthetic growth regulators had a positive effect on the formation of the mass of raw matter of winter wheat plants in the autumn and spring periods.Thus, the mass of raw matter of winter wheat plants increased by 3.4% during the autumn period under the influence of Vympel, by 12.8% by Amber acid. Azotofite, which exceeded the control index by 15.1%, showed the greatest efficiency.On 217 days after the emergence of the stairs, the increase in the mass of raw matter of plants under the influence of Vympel was at the level of 38.2%, Amber acid – 9%, Azotofite – 68% compared to control.On 227 day, the greatest effect on the growth of the mass of the raw matter of the plant was Azotofite (62.7% more than control), in the second place was the synthetic growth regulator Vympel, which increased the mass of the raw matter of the plant by 45% compared to the control.As a result of the research, it was found that the highest performance of photosynthesis was determined in versions using Azotofite and Vympel, where the net photosynthesis yield was 11.5 g/m2/day and 9.4 g/m2/day and exceeded the control values by 69.3% and 38.4% respectively.Thus, according to the results of studies of the physiological effects of synthetic growth regulators, it has been found that the most effective synthetic growth regulators that stimulate the assimilation processes of winter wheat during the studied periods are Azotofite and Vympel.

The authors present the results of many years research on the study of the growth regulators “ХЭФ ВР” and Stabilan BP influence on the yield and quality of winter wheat of new varieties – Alekseich and Adel, selected by the National Center of Grain named after P. P. Lukyanenko in the steppe zone of the Mozdok region, Republic of North Ossetia – Alania. The aim of our research was to improve the tech nology of winter wheat cultivation using the new generation plant growth regulators “ХЭФК”, which stimulates the growth and volume of the root system, strengthens the stem by reducing the length of internodes and increasing the diameter of the stem, prevents lodging of crops, and has a positive effect on yield and quality. Stabilan slows down the growth of stem cells in length, which leads to a decrease in plant height and thickening of the spike, providing an increase in yield and grain quality. To achieve this goal, the research tasks included studying the effect of plant growth regulators on the growth processes of winter wheat at the initial stages of ontogenesis, on the yield and quality indicators of winter wheat grains of the Alekseich and Adel varieties in the steppe zone of the Mozdok region of the Republic of North Ossetia – Alania. Our studies have shown that growth regulators had a positive effect on the processing of seed material and sowing of winter wheat varieties Alekseich and Adel. The grain yield is increasing; the increase in relation to control was up to – 1.36 t/ha. The growth regulators “ХЭФК” and Stabilan were studied; they had a positive effect on the quality indicators of winter wheat grain, on the protein content, and the weight of 1000 grains. The highest yield was obtained on the variant with the use of the growth regulator “ХЭФК” – 4.63 t/ha.

Increasing Demand

Abelmoschus sagittifolius Kurz is a medicinal plant with typical pharmacological of ginseng. However, the number of trees in the nature wild is declining rapidly due to the increasing demand for logging along with the narrowing of the distribution area and the low incidence of seed germination, affecting the use for researching and developing gene sources for drug production in many areas. In this plant, root is the most important organ of the plant, so the study of root formation in in vitro has been of great significance in assessing the effect of plant growth regulators on induction roots, as well as creating a source of starting material for studies on the biosynthesis of saponin in in vitro compounds as an alternative to outside planting. The results showed that after 2 weeks of culture, the germination rate was highest (88%) when the seeds were disinfected with HgCl2 0.1%, 3 minutes and then soaked in GA3 20,0 mg/L, 120 minutes, finally seed culture on MS + 20 g/L saccharose + GA3 5.0 mg/L + 7 g/L agar. The callus formation from hypocotyl in the environment on MS medium + 20 g/L sucrose + NAA 0.5 mg/L + BA 1.5 mg/L + 7 g/L agar was appropriate for root reduction and the best root formation was applied in the medium of MS + 20 g/L sucrose + IAA 0.3 mg/L + 7 g/L agar. In conclusion, the method of tissue culture is suitable for the formation of adventitious roots from callus formation from hypocotyl of Abelmoschus sagittifolius Kurz.

im. The aim of the study was to choose conditions for rooting improvement of in vitro cultivated plants of some species of Carlina L. genus. Methods. For receiving and rooting of aseptic sprouts, seeds of Carlina acaulis L., Carlina cirsioides Klok and Carlina onopordifolia Besser ex Szafer, Kulcz. et Pawl were subjected to presowing treatment with gibberellic acid solution (GA3) or indolebyturic acid solution (IBA). Sterilized seeds were planted in sterile Petri dishes on semi-solid Murashige, Skoog nutrient medium with half-strength concentrations of macro- and microsalts without growth regulators. Results. It was found that with the seed soaking of C. acaulis, C. cirsioides and C. onopordifolia in GA3 solution the percentage of root formation amounted to 33.3 %, 33.3 % and 22.2 % respectively. Presowing treatment of carlina seeds in IBA solution with concentration of 1000 mg for 2–4 hours before sterilization gave a positive effect: the percentage of root formation for C. acaulis, C. cirsioides and C. onorordifolia was 2.4–4.5 times higher compared to the treatment with GA3 solution. Conclusions. To form the root system of carlina plants it is effective to soak the seeds in the solution of IBA. Thus we were able to increase the percentage of rooting of C. sirsioides and C. onorordifolia plants to 100 %, C. acaulis plants – up to 80 % and avoid sprouts’ injury and changes in the concentrations of the IBA, which may occur during sterilization at high temperatures by using non-sterile solution of growth regulators.

Scientific research suggests that winter wheat cultivation technologies can be regulated by plant growth regulators. These substances have a complex effect on growth and development and facilitate plant growth and crop capacity. Three-year field studies were carried out using plant growth regulators of Azotophyte, Amber acid and Vympel to determine the dynamics of plant growth rates and their productivity. This made it possible to observe the influence of growth regulators before sewing and to establish their effectiveness at all stages of plant development. Seeds of winter wheat of the variety Jubiwata were treated with solutions of the substances under analysis. The experimental area was 40 m². The study demonstrated that the growth regulators do not influence the field germination rate of plants, but the percentage of germination was quite high in both control and experimental variants. As for the rates of plant height and root length, the first measurement of the average height of winter wheat plants in autumn demonstrated that Vympel was the most efficient. Its indicators exceeded the control variant by 3.4%. After the second measurement, the plant height increased in all variants. The fourth spring measurement showed that the most powerful was the effect by Amber acid. This compound significantly inhibited plant growth compared to other growth regulators and controls. The investigated plant growth regulators have a positive influence on the processes of root development of winter wheat plants in both autumn and spring time. This feature will provide a better nutrition of the plants. The weight of the dry matter after the first weighing was greater in the control and the variant treated with Nitrogen. The fourth weighing showed that the best effect on the dry matter mass was found by Azotophyte, which contributed to the increase of this indicator twice as much compared to the control. Amber acid, when used for pre-sowing seed treatment, exceeded the control value by 1.8 times. Stronger effect on the percentage of dry matter in the plant sample was found only by Vympel, under the influence of which this indicator was greater by 9 units compared to the control. The use of synthetic growth regulators significantly increases the productivity of winter wheat, namely the length of the complex ear, the number of grains and the weight of the compound ear. Thus, research has shown that plant growth regulators Azotophit, Amber acid and Vympel facilitate the growth and productivity of winter wheat plants of the Juvivat variety. Winter wheat crops can be treated with these substances before sowing. Determining the highest efficiency of each individual regulator, as well as the possibility of combining them to improve plant growth processes, requires further research.

The paper presents data from studies of the influence of growth regulators on the infection of winter wheat plants. To reduce the level of infection with parasitic diseases and the negative impact of environmental factors, we recommend spraying winter wheat crops with CuproTGK GK-Cu, GK-Zn, DAG-1, DAG-2 preparations. However, the positive effect of the investigated drugs is limited by fungistatic activity. The preparations can be used for prophylactic purposes to reduce the level of infection of winter rye with fungal parasites.
