摘要: Toxicity of heavy metal is a wide spread environmental problem affecting all life forms including plants. In the present study toxic effects metals, cadmium (Cd), chromium (Cr) and lead (Pb) on seed germination rate (%), index (G-index) growth (mm) Brassica rapa var. turnip have been investigated. The seeds were soaked either in distilled water (control) or aqueous solutions Cd, Cr Pb (1 g/l, 2.5 g/l 5 g/l) at 4°C dark for 24 hours. Prior to inoculation onto MS0 medium, washed with sterile inoculated without washing solidified medium 25 ± 2°C 16/8-hour photoperiod chamber germinate vitro. Such stress conditions revealed that by increasing concentration G-index value decreased significantly, suggesting their effect B. turnip. This further experiment resulted in...
