Abstract

This study applied lead salts hydroponic tea plant, observed and analyzed Pb accumulation and ultra-structure localization in the cells of root, stem, leaves by the TEM-EDS method. The results showed that most of Pb evenly distributed on the cell wall of root cells, only few Pb distributed on the plasma, cytoplasm, vacuole membrane and intercellular space. While, Pb on cell wall of stem were numerals and small, and a little on plasma, vacuole membrane and chloroplast. Pb in leaves were mainly on plasma and vacuole membrane, there were only a little on the cell wall of leaves.

Key words

hydroponic tea / Pb accumulation / TEM-EDS / ultra-structure localization
