ЕФЕКТИВНІСТЬ ЗАСТОСУВАННЯ РЕГУЛЯТОРІВ РОСТУ РОСЛИН У ПОСІВАХ ЛЮПИНУ БІЛОГО (LUPINUS ALBUS L.)

Abstract

The influence of biological preparations Emistym S and Epin on the formation of symbiotic systems at plant roots against the background of spontaneous inoculation by local populations of Bradyrhizobium sp. (Lupinus), seed productivity and grain quality of white lupine variety Makarivskyi in soil and climatic conditions of the Western Forest-Steppe of Ukraine. It was established that the local races of lupine tuberculosis bacteria in the soil and climatic conditions of the Ternopil region were virulent, which accordingly contributed to the growth of pink popatoes, mainly, on the main root of the plants. The biological preparation of Ukrainian production Emistym S had a more active influence on the formation of the symbiotic apparatus on the roots of white lupine compared with the brasinosteroid of the Belarusian production Epin. Plant growth regulators (PGR) have slowed the aging and lysis of potatoes.
 The biological yield of seeds of white lupine variety Makarivskyi in soil and climatic conditions of the Western Forest-Steppe of Ukraine (Ternopil region) in the control variant made 27,4 h / ha. For seed treatment with plant growth regulators Emistym S and Epin – 29,5 and 28,3 h / ha. Pre-sowing seed treatment with Emistym S significantly increased seed productivity of white lupine by 2,1 h / ha (7,7%) compared to the control. Due to the effects of Emistym S, the number of seeds per plant increased by 25,5%, Epin – 10,4% before control. A significant difference was found in the index of seed weight per plant, with exogenous treatment of seeds with the drug Emistym S, the above indicator increased by 39,5% compared to the control and PGR Epin – 17,2%. Biological preparations also influenced the mass index of 1000 seeds. Studies have shown a significant increase in the above figure by 11,7% with the use of Emistym S.
 PGR Emistym S and Epin significantly affected the qualitative composition of white lupine seed substances. The use of Emistym S and Epin revealed statistically significant increases in organic matter, including protein (7.9, 2.9%), proteins (8.1 and 1.9%), oils (5.9 and 2.2%), and fiber (7.9 and 4.0%). These PGR did not significantly affect the accumulation of mineral compounds of phosphorus, potassium and ash content of white lupine seeds for cultivation in the soil and climatic conditions of the Western Forest-Steppe of Ukraine
 Improving the intensity of symbiotic systems formation at the roots of plants, during the pre-sowing treatment of the seeds of PGR Emistym S and Epin, contributed to the formation of higher productivity and better quality indicators of white lupine variety Makarivskyi.
