Accumulation Characteristics

The selenium accumulation characteristics of Solanum nigrum with different ploidy were studied by the pot experiment, and the biomass, selenium content and selenium accumulation of diploid (Solanum photeinocarpum), tetraploid (Solanum photeinocarpum) and hexaploid (Solanum nigrum) plants were determined, the results showed that there was a difference between the biomass and selenium content of three kinds of ploidy plants of S. nigrum. The biomass of various organs and shoots of hexaploid S. nigrum plants was significantly higher than that of tetraploid and diploid plants. In terms of selenium content and selenium accumulation, the hexaploid plants had the highest selenium content and selenium accumulation in stems, leaves and shoots. After comprehensive comparison, the hexaploid S. nigrum has large biomass and strong selenium-enriching ability, so it can be used as an excellent plant material for soil selenium absorption and transformation.

Cadmium Contaminated Soil

To study the cadmium accumulation characteristics of Solanum nigrum with different ploidies, the biomass, cadmium content and cadmium accumulation of diploid (Solanum photeinocarpum), tetraploid (Solanum photeinocarpum) and hexaploid (Solanum nigrum) were measured by a pot experiment. The results showed that the biomass of roots, stems, leaves and shoots of S. nigrum plants with different ploidy all ranked as follows: hexaploid > tetraploid > diploid. Cadmium content and cadmium accumulation in stems, leaves and shoots of hexaploid plants were significantly higher than those in tetraploid and diploid plants, and the cadmium translocation factor and translocation accumulation factor of hexaploid were the largest, too. Therefore, hexaploid S. nigrum had a highest ability to extract and transport cadmium, which can be used as an ideal plant for remediation of cadmium-contaminated soil.

Relevance. Biofortification of agricultural crops with selenium is considered to be the most promising method for the human selenium status optimization.Methods. Effect of foliar biofortification of cauliflower, Polyarnaya Zvezda cv, with sodium selenate of different concentrations on yield, selenium content and biochemical characteristics of plants were investigated.Results. Enrichment of plants with selenium increased yield by 1.23-1.31 times, sugar content – 1.6 times, ascorbic acid concentration – 1.52-2 times. On the contrary, the treatment did not affect pholyphenol content and antioxidant activity of ethanolic extracts of plants. Selenium accumulation levels decreased according to inflorescences > leaves > roots. Sodium selenate solution at 75 mg/L concentration increased mass of cauliflower leaves 1.9 times and roots – 1.5 times. Consumption of 100 g of cauliflower fortified with 50 mg/L sodium selenate solution provided 100% of the daily adequate selenium consumption level. Utilization of higher sodium selenate concentrations ensured 127% and 418% of the daily adequate consumption level in case of 75 mg/L and 100 mg/L concentrations respectively. Taking into account insignificant differences between sugar content and antioxidants in cauliflower inflorescences fortified with different doses of selenium the most suitable concentration to be used was 50 mg/L.
