Effect of Chromium on Physiological Characteristic of Flue-Cured Tobacco

Ning Lü

Abstract

The present study was conducted to study the effect of different Chromium(Cr) concentration on physiological characteristics of flue-cured tobacco by pot experiment.The result showed that root activity,chlorophyll content and protective enzyme activity were downtrend,while the cell membrane permeability,activity of tobacco roots and the malondialdehyde(MDA)content were increased with the increase of Cr concentration.It was determined that the growth and development were impaired significantly when the Cr concentration in soil was over a critical concentration.
