Email this article THE INFLUENCE OF THE COMPLEX ACTION OF THE RETARDANT CHLORMEQUAT CHLORIDE AND THE GROWTH STIMULANT TREPTOLEM ON THE MORPHOGENESIS AND PRODUCTIVITY OF OILSEED POPPY
Abstract
The usage of a mixture of growth regulating preparations on poppy plants optimised the leaf anatomical structure, and the assimilative parenchyma thickened through the growth of its cells. Under the influence of the complex of preparations, the linear size of spongy parenchyma cells in the test variants increased.
The growth in the number of leaves, the prolongation of their life, the appearance of a larger leaf surface, more robust chlorenchyma and an increase in the content of chlorophylls in its cells result in an increase in the net productivity of photosynthesis and gross photosynthetic productivity of poppy plants and cenosis in general. The application of the complex of preparations also resulted in increased stem branching, which in turn led to an additional number of fruits (capsules). The increase in the yield of oilseed poppy under the impact of a mixture of chlormequat chloride and treptolem was mainly due to changes in the crop structure. At the same time as the number of fruits (capsules) increased, the weight of seeds in capsules and the weight of a thousand seeds also rose. The use of the mixture of preparations did not lead to a violation of toxicological standards since the content of chloromequat chloride and treptolem in the seeds did not exceed the permitted limits. The increased yield of oilseed poppy crop under the influence of a mixture of chlormequat chloride and treptolem was accompanied by an oil content increase in the seeds. The quality of poppy oil increased due to an increase in the proportion of unsaturated fatty acids.
