Studies on the Precipitation of Lead Ion and the Inhibition of Plant Growth
초록
This study was carried out to investigate the formation of precipitates between lead ion and the essential anions of plants, the effects of lead concentration on seed germination and plant growth in water and soil culture, and the germinating and growing recovery of inhibited seed germination and plant growth by lead. Four kinds of the seeds (Glycine max M., Triticum vulgare V., Setaria viridis (L) P. De Beauvois, and Digitoria sanguinalis (L) Scopoli var) were germinated and growth in water and soil culture included the different concentrations of lead for five days. The seeds and plants inhibited germination and growth by lead were transferred to lead free Hoagland solution and the growing recovery was observed. The precipitates of lead ion were observed in the solution of both acidity and alkalinity included each anion of
