Negative Effect

<p>The effect of increasing salinity to the morpho-metric parameters of Salix alba L., which dominated in the coastal areas on rivers of Steppe Dnieper, is investigated. We added Mg as salt MgSO<sub>4</sub> * 3H<sub>2</sub>O in the range of concentration: 0.5, 1.0, 1.5, 2.0 and 2.5 g/l in a solution of willow cuttings. In the solution was added and plant growth regulator "Kornevin" the synthetic origin. The negative effect of salt at a concentration from 1.0 g/l to 2.5 g/l in the dynamics of growth and development was found. The correlation between the size and salinity in dynamics of growth and development of plant were demonstrated: in the growth of shoots (R = 0.83, 0.91 and 0.95), in the growth of roots (R = 0.92, 0.68 and 0.84) respectively depended from salt concentration. The length of the leaf blade was from 4% to 8%, from 7% to 43%, from 333% to 11% (R = 0,68, 0,93, 0,61), depending on the concentration of salt and during observing compared with control (distilled water). "Kornevin" and combined effect of salt increased the length of the leaf blade growth by 4-5, 2-4, 3-5 times, the roots by7 and 3-14 times, the shoots by 3-4, 6-7 and 5-7 times in the dynamics of growth compared with control (MgSO<sub>4</sub>, 2,5 g/l).</p> <p>The recommendations regarding for the advisability of using the plant growth regulator "Kornevin", as very effective plant growth preparation that promoted rooting and activated physiological processes of plant organism, expressed protective effect in conditions of excessive salinity, were provided.</p> <p class="Style1"><em>Key words</em><em>:</em><em> </em><em>the morpho-metric index, the plant growth regulators, abiotic factors, salinity factor, the adaptation.</em><em></em></p>

Effect On Yield

Field experiments were conducted in Alabama from 1992 through 1994 to evaluate the potential of the methyl ester of bensulfuron applied at sublethal rates as a plant growth regulator for reducing plant height and boll rot in cotton. Bensulfuron at 0.017 and 0.034 g ai/ha or mepiquat chloride at 10 g ai/ha was applied POST alone at the pinhead square or early-bloom stage of cotton growth or sequentially at 0.017 followed by (fb) 0.017 g/ha, 0.034 fb 0.034 g/ha of bensulfuron and 5 fb 5, 10 fb 10, 10 fb 20, or 20 fb 20 g/ha of mepiquat chloride. Mepiquat chloride had no effect on yield in 1992 and 1994 but decreased yield when applied sequentially in 1993. Bensulfuron was generally detrimental to first position fruit retention, and it delayed maturity. Treatments that reduced plant height did not reduce boll rot. Bensulfuron treatments that reduced plant height also reduced yield; therefore, the potential for its use as a growth regulator in cotton appears limited.

Growing Conditions

A 3-yr field experiment was conducted at the Scott Experimental Farm to determine the effect of the growth regulator, triapenthenol, on the growth and development of Argentine canola (Brassica napus L.). Triapenthenol reduced plant height 25–45 cm under optimal growing conditions. Increases in yield, branches and total pods were observed. Application at the bud stage was more effective than earlier treatment in the rosette. It was concluded that triapenthenol application to canola could be a useful management tool, particularly under optimal growing conditions.Key words: Canola, growth regulator, RSW-0411, lodging

We used the plant growth regulator “Kornevin” in order to accelerate rooting and reducing of exogenous pressures on the plant. We registered the Aminotransferase nonspecific reaction towards anthropogenic pressure, which was associated with the formation of non-specific mechanisms of adaptation to support the homeostasis. We revealed the significant differences between experiment and control in index of protein synthesis and metabolism depending on the conditions of growth and development. Protective and leveling effects of growth regulator have been proved. The advisability of using the "Kornevin" as an adaptogene and a protector in variable environmental conditions have been indicated.</p><p><em>Salix alba L., increased level of salinity, growth regulators, alaninaminotransferase, aspartataminotransferase, adaptogene, anthropogenic factors</em><em></em></p>

The article presents an analysis of experimental data demonstrating the rationality of the use of plant growth regulator Zircon on some representatives of the genus Iris L. in the Bashkir Cis-Ural. It is shown that the effect of the substance at a concentration recommended by the manufacturer varies depending on the species and varietal specificity of plants. As a result of tests of the drug, it was found that Zircon stimulates the development of leaf blade and fruit formation, lengthens the flowering phase for some varieties of Iris and to a lesser extent affects other biometric indicators.

Introduction: This study aims to obtain concentration of shallot extract (Allium cepa ) and growth regulators to increase growth of Mucuna bracteata. Mucuna is a land cover plant that must be planted in oil palm plantation areas. It is very important to be able to cover the planting area. Materials and Methods: This study used two factorial in randomized block design. The first was concentration of shallot extract per 100 ml distilled water consists of 4 levels, such as control (B0), 10 cc (B1), 20 cc (B2), 30 cc (B3) and the second was the auxins-plant growth regulator consists of 4 levels: Control (G0), 100 ppm (G1), 200 ppm (G2), 300 ppm (G3). Data analyzed with ANOVA with a significant 5% and continued with the DMRT using SAS version 9.1.3. Results: It was found that effect of concentration of shallot extract had a significant effect on survival percentage of Mucuna bracteata at a concentration of 10 cc (B2) after opening the lid at four weeks after planting (WAP) and did not change until 8 WAP. Likewise, the number of leaves at the control concentration (B0) at the age of 6 WAP, and a concentration of 10 cc (B1) at the age of 7-8 WAP. The concentration of growth regulators and their interactions did not significantly affect the survive percentage and number of leaves in Mucuna bracteata.

The Impact

In the formation of the winter wheat yield, the protection of the crop from pests, stress, pesticides and adverse abiotic factors is one of the important elements of the technology. To increase yield and reduce the impact of adverse factors in winter wheat protection systems, plant growth regulators are used. In the conditions of the Ryazan region in 2019-2020, the effectiveness of the use of tank mixtures of pesticides with the growth regulator Energia-M (0.01 kg/ha) in the protection systems of winter wheat of the Danaya variety was studied. In the variant with the use of a tank mixture of pesticides with a growth regulator, a statistically significant excess of yield was noted in comparison with the control (without treatment) by 1.4 t/ha (31 %) and with the variant with treatment using a tank mixture without the use of a growth regulator - by 0.9 t/ha (18 %). Under the influence of the plant growth regulator, a decrease in the negative impact of pesticides on growth processes, an increase in crop yield by 18 % due to the formation of an additional number of productive stems (80 pcs / m2 ) were noted and a higher net operating profit was obtained compared to the protection system without a plant growth regulator.

<p>The effect of <em>MgSO<sub>4</sub></em> on morphometric specifics of the <em>Salix alba</em> L., which characterized by high rates of growth and development is investigated. Mg<sup>2+ </sup>was added in the form of <em>MgSO<sub>4*</sub>3H<sub>2</sub>O</em> at a concentration of 2.5 g/l considering of salt water content in the research solutions with <em>S. alba</em> L. and  combined with plant growth regulator (GR) of natural origin Humisol. These studies have shown toxicity of<em>MgSO<sub>4</sub></em> at a concentration of 2.5 g/l during all the period of growth and development. So, <em>MgSO<sub>4</sub></em> had toxic effect on plant growth and development within whole period of observation. We registered negative correlation (R = - 0.99) between toxic properties of salt and the age of the studied plants (for example, the growth rate of shoots and leaf blades by <em>S. alba</em> L.) and positive correlation (R = 0.99) while studied the root growth rate, which was caused by the direct contact of rhizosphere and negative stressors.</p><p>The GR Humisol accelerated the rate of physiological processes of growth and development of shoots and roots in 2-3 times, but the growth of leaf blade was not activated regards the control. The combined effect of magnesium salts and GR levelled toxic concentrations of magnesium sulphate were accelerated plant growth or stimulated growth up to control values, promoted adaptation mechanisms of plants and provided a protective role against excessive salinity. We suggested using the Humisol as a natural product, vermiculture, adaptogene, protector, and fertilizer agent of natural origin, which provides for biota to consume the environmental services without damage to the environment under conditions of excessive pressure of salt stress on plant organism.</p>
