- Purpose of Project
A group of angiospermous herbaceous plants were assayed for symptomatic foliar changes in response to RDX contaminant levels found in soils of military ranges. Among five species selected for testing on the basis of RDX tolerance, only prickly sida (Sida spinosa) exhibited foliar symptoms upon exposure. At plant maturity red patches were produced in the leaf margins and interveinal chlorosis developed. Other members of the family Malvaceae are used to produce a red tea rich in anthocyanins. Because of these symptoms, there is potential for using prickly sida as a cost effective field and laboratory indicator of RDX contamination and for RDX phytoremediation.
