Abstract

 

The effect of lead on accumulation of Pb; mineral composition in roots, shoots and leafs; growth-development; chlorophyll and water content of tomato (Solanum lycopersicum L. cv. Falcon) seedlings was tested under doses of 0-control, 75, 150 and 300 mgl-1 Pb. Lead accumulation was defined by elevated concentrations as 75 to 300 mgl-1 Pb in root, shoot and leaf tissues. Element uptake by roots, shoots and leafs was negatively affected by in raised lead concentrations, especially in 300 mgl-1 Pb . Root elongation and plant height; root, shoot and leaf fresh and dry biomass; leaf area were negatively affected by increasing lead concentrations. Tissue water content (TWC), growth tolerance index (GTI), chlorophyll a, chlorophyll b and total chlorophyll content limited by lead toxicity.

 

Key words: Lead (Pb), toxicity, growth, nutrient, chlorophyll, water status.
