Abstract
Selenium-enriched vegetables have high nutritional value and good flavor, which are beneficial to human health. To improve the selenium uptake of watercress, a pot experiment was conducted to study the effects of selenium combined with 400-fold diluted extracts of Artemisia argyi and tartary buckwheat (Fagopyrum tataricum) straw on its growth and selenium accumulation. Both extracts promoted root and shoot biomass, increased leaf chlorophyll and carotenoid contents, and enhanced POD activity. Compared with single selenium treatment, A. argyi straw extract raised root and above-ground selenium accumulation by 46.38% and 16.69%, while tartary buckwheat extract increased it by 39.10% and 5.41%. Their combined treatment increased selenium accumulation by 47.28% and 19.64%. The correlation analysis showed that the selenium content in the roots and above-ground parts of watercress had a positive correlation with the biomass of watercress, chlorophyll content, carotenoid content, and POD activity. In conclusion, the two extracts can promote watercress growth and selenium enrichment, and their combined application achieves a better effect.
期刊介绍:
The International Journal of Phytoremediation (IJP) is the first journal devoted to the publication of laboratory and field research describing the use of plant systems to solve environmental problems by enabling the remediation of soil, water, and air quality and by restoring ecosystem services in managed landscapes. Traditional phytoremediation has largely focused on soil and groundwater clean-up of hazardous contaminants. Phytotechnology expands this umbrella to include many of the natural resource management challenges we face in cities, on farms, and other landscapes more integrated with daily public activities. Wetlands that treat wastewater, rain gardens that treat stormwater, poplar tree plantings that contain pollutants, urban tree canopies that treat air pollution, and specialized plants that treat decommissioned mine sites are just a few examples of phytotechnologies.
