| This study was carried out to investigate the effects of Zn and Pb concentration on seed germination and plant growth in water and soil culture, and the frequency of chlorosis invegetation and the relationship between plants and soil in the Sambo mine. The inhibition of germination were observed in 1000ppm of Zn, 10ppm of Pb and 5000ppm of Zn + Pb, but germination was more stimulated in 10ppm of Zn than control. The symptoms of chlorosis and abnormality were occurred in plant leaves grown to the soils treated with more than 1000ppm of Pb. Reasons of chlorosis were considered as an antagonistic effect of other metals towards uptake of iron by the plant in Zn treatment. The contents of Zn and Pb in fruits were lower than those of leaves, and that was remarked in case of Pb. With increasing rate of Zn and Pb treatment, chemical components of soils in pot culture were accompanied by slight decrease in pH, total nitorgen and exchangeable K. Chlorotic individuals of 10 species were shown in the areas of the Sambo mine. Chlorotic symptoms were especially extensive and severe in Sophora angustifolia, Populus alba, Spiraea prunifolia, Amorpha fruticota, Lespedeza bicolor and Salix dependens. Plants in the investigated areas grew in soils containing Zn of 311ppm and Pb of 151ppm on an average, and accumulated Zn of 2084ppm and Pb of 49ppm. |
