Abstract

Chromium (Cr) is a highly toxic heavy metal for microorganisms, animals and plants. Due to its widespread industrial use, it has become a serious pollutant in a diverse array of environments. Excess Cr is a stressful factor for plants that can limit their growth. It can also induce OXIDATIVE STRESS in plants. In this research, four-week sunflowers which were grown under controlled greenhouse conditions, were exposed to various concentrations of Cr (0.0, 0.001, 0.01, 0.1. 1.0, 5.0, 10.0 mM) to determine how CHROMIUM would affect the growth and OXIDATIVE STRESS induction in the root part of sunflower. The field survey showed that 5 and 10 mM concentrations of Cr led to lowering GROWTH PARAMETERS (such as; length, fresh and dry weigh) in sunflower's roots. However, the lower concentrations showed no significant differences compared to the control. In contrast, the content of malondialdehyde as the OXIDATIVE STRESS indicator, increased in this two high level CHROMIUM. In addition, CHROMIUM treated sunflower roots showed increased proloine contents in 5 and 10mM concentrations. In contrast, protein content reduced in 0.001 mM consentration of CHROMIUM compared to the control. However, reduced ascorbate contents in roots occurred with the increase in dehydroascorbate and total ascorbate amount under 1, 5 and 10 mM concentration of Cr treatment. Despite some stress symptoms, sunflower roots accumulated high amount of CHROMIUM, and it seemed that chelation and compartmentation of Cr in the roots was a tolerant mechanism for sunflower which occurred under CHROMIUM stress.
