| description | The specificity of the action of antigibberelin drugs is that they can influence the processes and intensity that
cannot be corrected by agronomic measures of cultivation. The purpose of the work was to scientifically substantiate the
use of plant growth inhibitors with an antigibberelin type of action as an element of soybean cultivation technology, to
identify their effect on growth, development and productivity.
The research was carried out on a soybean plants of the Triada variety. At a height of shoots 10-15 cm plants were treated
with aqueous solutions: 0.5% tebuconazole, 0.2% ethephon and 0.5% chlormequat chloride until complete wetting of the
leaves. Control plants were treated with water. During the research, morphological parameters, leaf surface area, and organ
mass were defined.
It was established that the use of plant growth inhibitors with an antigibberelinic mechanism of action (the ethylene producer
esfone (0,2 %), the triazole-derived retardant tebuconazole (0,5 %) and the onium preparation chlormequat chloride (0,5
%) on soybean plants led to morphological and anatomical changes: decreasing of the mass of leaves and stem, increasing
the thickness of the stem and root collar. The preparations reduced the length of internodes of soybean plants,, that created
the preconditions for plant resistance to lodging.
Plant growth inhibitors had different effects on the leaf surface area of soybean plants: there was an increase in this
indicator by 24% for the use of chlormequat chloride, and processing with esfon and tebuconazole led to a decrease of 26%
and 23% accordingly.
Different effects of retardants were found on the length of the main root. Under the action of esfon the length of the main
root decreased by 20%; the application of both chlormequatchloride and tebuconazole, this indication increased accordingly
by 43% and 37%.
The question of studying the influence of modern plant growth regulators with a different mechanism of action on the
productivity of different varieties of legumes remains relevant. |
