Uptake of lead by barley hordeum distichon l. roots and its relation to potassium

Uptake of lead by barley hordeum distichon l. roots and its relation to potassium

Turkish Journal of Biology 12(2): 128-133

ISSN/ISBN: 1300-0152

The environment is heavily polluted with lead from various sources and plants are effected by this pollutant. Plants absorb lead from the soil through the roots. The decrease of potassium which is vital for the plants indicates an indirect sing of heavy metal poisoning. In this investigation barley roots were kept in lead solutions for certain periods and then the lead were extracted. The amount of lead in the extracts was determined by Atomic Absorption Spectrophotometer. The potassium content of the extracts was determined by Flamephotometer. The potassium content of the roots were found to be decreased when the lead has been taken by barley roots. These results indicated that lead taken by barley roots, might be concentrated at a dangerous level in the plant.
