Assessment of heavy metals phytotoxicity using seed germination and root elongation tests: a comparison of two growth substrates.

Abstract

Seed germination and root elongation test is used to evaluate hazardous waste sites and to assess toxicity of organic and inorganic compounds. Paper substrate, especially circular filter paper placed inside a Petri dish has long been used for this test. Same reports indicate that filter paper might interfere with the toxicity of inorganic substances… (More)
