Chromium phytoaccumulation and tolerance potential of Coffe Pod: Cassia tora (L.) Roxb. grown in chelate and fertilizer assisted soil

Chromium is a heavy element which plays a vital role in metabolism of cholesterol fat and glucose while, at higher concentration it is toxic and carcinogenic. Pot culture experiments using hexavalent Chromium (Cr +6 ) with combination of chelater and fertilizer were performed to assess the growth and Chromium bioaccumulation in 60 days old plants of Coffe pod. Root and shoot length, fresh and dry matters considerably increased in fertilizer application than other treatments. Chromium bioaccumulation was more in roots than leaves and stems. Bio-Concentration Factor (BCF), Total Accumulation Rate (TAR) indicated highest values i.e., 0.203 and 2.514 respectively using Cr +6 -EDTA-FRZ (50ppm) whereas Transportation Index (TI) was highest (2.510) using 50ppm of Cr+6.
