Impacts of root pruning and magnetized water irrigation on the phytoremediation efficiency of Celosia argentea
Pot experiments were conducted to evaluate the effects of magnetized water irrigation (100 mT) and root cutting (three pruning intensities) on phytoremediation efficiency of Celosia argentea. In the absence of magnetic field treatment, low root cutting intensity increased the dry weight of the below...

description | Pot experiments were conducted to evaluate the effects of magnetized water irrigation (100 mT) and root cutting (three pruning intensities) on phytoremediation efficiency of Celosia argentea. In the absence of magnetic field treatment, low root cutting intensity increased the dry weight of the below-ground and aerial parts of C. argentea. Moderate and severe cutting intensities decreased the biomass yield of the plant roots by 11.3% and 31.0%, and increased the dry weight of aerial parts by 75.9% and 27.6%, respectively, alleviating the detrimental effects of these pruning treatments on the plant roots. In the presence of magnetic field treatment, 10% and 25% of pruning treatments increased the dry weight of plant roots by 52.1% and 33.8%, and 33% pruning treatment decreased it by 14.1%. Under both irrigation treatments, low and moderate root cutting strategies did not affect the take up of Cd by the plant roots, while severe cutting decreased it significantly. Enzyme activities decreased with the increment of pruning intensity, and magnetic field can alleviate the negative impact, increasing the capacity of the root pruned species to scavenge the excessive ROS induced by the accumulated Cd. The results showed that root pruning enhanced the phytoremediation efficiency of C. argentea, and this effect was enhanced when combined with magnetized water irrigation. |
