Cu and Zn tolerance and responses of the Biochemical and Physiochemical system of Wheat
Journal Title: Журнал ÑтреÑÑ-физиологии и биохимии - Year 2012, Vol 8, Issue 3
Abstract
The concentrations of heavy metals such as Zinc and copper in the environment are currently increasing, due mainly to human activities. Zinc and copper are essential elements for several biochemical processes in plants. Any of these metals, at high concentrations in soil, can cause severe damage to physiological and biochemical activities of plants. Plant growth, pigment concentration, biochemical parameters, uptake of heavy metals were investigated in 30-days old wheat ([i]Triticum aestivum[/i] L.) in response to Cu and Zn stress. The plant exhibited a decline in growth, chlorophyll content, protein and DNA, RNA content carbohydrate, but proline, total phenol and H[sub]2[/sub]O[sub]2[/sub] content increased at high concentration of Cu and Zn.
