Abstract

 Chromium is an essential micronutrient in human and animals. Trivalent form of chromium as an important component of a balanced diet is necessary for proper carbohydrate and lipid metabolism. One of the suitable ways for preventing of chromium deficiency and its undesirable effects is using of chromium accumulator plants in daily diets. For this purpose, Cr+3 and Cr+6 accumulation effects on GROWTH and CHLOROPHYLL content in parsley plants were studied. Seedlings of parsley (Petroselinum crispum) were grown in hydroponic culture (Hoagland) containing various concentrations of Cr+3 (0.1, 0.25, 0.75,1, 1.5, 2 and 3 mg/l) and Cr+6 (0.1, 0.25, 0.5 and 0.75 mg/l) for 5 weeks. After harvesting, the influence of these ions on root and shoot dry weights, root and shoot lengths and CHLOROPHYLL (a, b and total CHLOROPHYLL) content was studied. Besides, chromium accumulation was determined in roots and shoots. Data analysis was carried out and means were compared at 0.05 level. Results showed that with increasing Cr+3 and Cr+6 concentrations in medium, the root and shoot dry weights and lengths and CHLOROPHYLL content decreased. Significant decrease in the root and shoot dry weights were observed at 3 mg/l and 2-3 mg/1Cr+3, respectively. In plants treated by Cr+6 , significant decrease in the root and shoot dry weights was observed at 0.75 mg/l. Cr+3 caused significant diminishment in the root and shoot lengths from 0.75 mg/l up to 3 mg/l. While significant decrease in the root and shoot lengths of plants treated by Cr+6 was observed at 0.75 mg/l and 0.5-0.75 mg/l, respectively. Decrease of CHLOROPHYLL a, b and total CHLOROPHYLL were significant at the highest Cr+3 concentrations (3 mg/l). The levels of CHLOROPHYLL a, b and raw CHLOROPHYLL decreased significantly at 0.25 mg/l and higher concentrations of Cr+6. With enhancing Cr+3 and Cr+6 concentrations in medium, the levels of these ions in the roots and shoots increased significantly. Chromium accumulation in the roots was much higher than the shoots.
