Abstract

The effect of 2,6-dipyridinium selenabicyclo[3.3.1]nonandibromide (996 zh) on the level of lipid peroxidation (LPO), on the activity of glutathione reductase (GR) and on the morphometric parameters of oilseed radish seedlings under normal conditions and under stress (200 mmol NaCl) has been studied. It has been established that the substance 996 zh at a concentration of 100 μm exerted an antioxidant effect reducing the level of lipid peroxidation and increasing the activity of GR. In connection with that the germinating ability of seeds and the biomass of the roots and stems of seedlings increased, both under normal conditions and under stress conditions.The concentration of the substance 996 zh of 1000 μmol had a toxic effect, increasing the LPO level in normal conditions, but neutralized the effect of stress due to the addition of NaCl. This concentration had a slight inhibitory effect on germinability and on root development in seedlings. However, the same concentration of the substance 996 zh (1000 μmol) had a positive effect on the development of shoots under both normal and stressed conditions.

Highlights

Eastern Siberia covers the territory of the Central and Northern Taiga of Russia
Oilseed radish (Raphanus sativus L. var. oleiferus Metzg.) is promising for outspread due to its cold resistance, short growing season and accumulation of large yields of high-protein green mass.It is grown as a fodder, green manure, oilbearing and strip culture
Selenium is known to play a large role in antioxidant plant protection (Mugesh et al, 2001).In connection with this, at the first stage of our work, we determined the content of diene conjugates and the activity of glutathione reductase

Summary

Introduction

Features of crop production in this region are dependent on harsh climatic conditions. Due to the fact that the climate in this region is continental and sharply continental, the main focus of agronomy production is on spring crops such as wheat, rye, barley and oats. In addition to these main crops, cruciferous field crops are widespread. To more fully use the potential of the culture, the efficiency of cultivation and the expansion of its distribution areas, it becomes necessary to develop its cultivation technology and identify the most important biological features (Dorofeevet al., 2013)
