The Optimal Root Length for Vetiveria zizanioides When Transplanted to Cd Polluted Soil

Int J Phytoremediation. 2015;17(1-6):563-7. doi: 10.1080/15226514.2014.922930.

Abstract

In order to facilitate transportation and accelerate growth, roots of Vetiveria zizanioides must be pruned before transplanting. The present research is aimed to investigate the best root length for vetiver grown in cadmium (Cd) polluted soil. The results indicated that 6 cm root-length plant (RLP) was the best candidate in phytoremediation of Cd-contaminated soil for its stronger tolerance and better growth promoting activities.

Keywords: Cd; indole-3-acetic acid; root elongation; root length; toxicity.
