Uptake and distribution of lead in tobacco (<em>Nicotiana tabacum</em> L.)

Uptake and distribution of lead in tobacco (<em>Nicotiana tabacum</em> L.)

Six Nicotiana tabacum varieties were in vitro cultured and experimentally exposed to lead in order to estimate lead uptake and distribution in tobacco plantlets and to observe possible differences depending on variety. Fifty-day-old plantlets were exposed to four Pb rates ranging from 0 to 200 mg dm...
