Effects of Zn2+ Stress on Radish(Raphanus sativus L.)Seeds Germination, Seedlings Growth and Chlorophyll Content
[Objective] The research aimed to study the effects of Zn2+ stress on radish seeds germination, seedling growth and chlorophyll content, to better know the stressing effects of heavy metal Zn2+ on growth and development of green plant. [ Method] The radish seed was Baoluolhao. Zn2+ concentration was 12.5, 25.0, 50.0 and 100.0 mg/ml, respectively. Take deionized water as control. [Result] The results showed that Zn2+ concentration changes could not affect seeds germination of radish. While with the increasing of it, the morphology, root length, form of root hair and the content of chlorophyll of radish seedlings were inhibited extensively. [Conclusion] The study provides a scientific basis for further carrying out soil remediation.
