| Abstract | ||
| The effect of detergent-polluted water (DPW) at the concentrations 0.52, 1.05, 2.10, and 4.20 g l-1 (the recommended) on the growth of tomato plants was assayed. Seed germination and seedling length were increased with the two lower concentrations 0.52 and 1.05 g l-1 , and decreased with 2.10 and 4.20 g l-1 (DPW) concentration. The growing seedlings and plants were dwarfed, malformed and brownish with the increase of the detergent concentration. The two higher concentrations reduced the dry weights of root by 25 and 81 % and the shoot by 11-57 %. The number of surviving plants, and chlorophyll contents were also decreased . Carotene at 5-leaves stage was decreased by 13 and 25%, and slightly increased at the 8-leaves stage with the 0.52 g l-1 (DPW) concentration and fluctuated around the control treatment at the flowering stage. The total soluble proteins of roots and shoots were clearly increased with the two lower concentrations, and sharply decreased by 24 and 50 % with the 2.10 and 4.20 g l-1 concentrations, respectively. The protein pattern showed changes, (as compared with the control plant proteins), where new and missed proteins bands were detected, at each detergent concentration. All these changes are related to the changes observed on the growth and health of tomato plants. | ||
