Abstract
Chromium is a potential toxic heavy metal which does not have any
essential metabolic function in plants. Chromium is a natural pollutant
occurring in soil and water imposing adverse effects on plant growth. In
addition to imparting growth retardation, many plants are capable of
accumulating Cr ions from soil/water. Coleus amboinicus is an important
medicinal plant extensively used in traditional and Ayurvedic medicines. Toxic
effects of Cr on C.amboinicus cultivated in Hoagland medium artificially
contaminated with 150µM K2Cr2O7 resulted in
growth retardation. Growth rate and Cr toxicity levels are assessed in terms of
shoot length, root length, leaf area and Tolerance index. Secondary metabolites
analysis using GC-MS and the impact of Cr on growth pattern and distribution of
secondary metabolites are discussed.
