Mitigating cadmium stress in Phaseolus vulgaris through nano silica-induced growth and cadmium uptake.
Cadmium (Cd) is a highly toxic heavy metal element widely in the natural environment. To investigate the effect of nano silica (SiO2 NPs) on the cadmium (Cd) accumulation in Phaseolus vulgaris, SiO2 NPs (100 and 200 mg/L) was sprayed on the leaves of P. vulgaris, and the growth and Cd accumulation under Cd stress were assessed. SiO2 NPs increased the biomass, photosynthetic pigment content, peroxidase (POD) activity, and Cd content of P. vulgaris under Cd stress. Compared to Cd treatment, the concentration of 200 mg/L SiO2 NPs increased the Cd contents in roots and shoots of P. vulgaris by 4.97% and 13.34%, respectively. Furthermore, correlation, principal component, and cluster analyses revealed that the shoot Cd content had the closest relationship with the photosynthetic pigment content and root and shoot biomass. Therefore, SiO2 NPs can mitigate Cd stress, promote the growth, and increase Cd accumulation of P. vulgaris, which is not suitable for the production of P. vulgaris in Cd contaminated areas.
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.
