Effects of the application potassium silicate (PS) and an arbuscular mycorrhiza fungus (AMF) (Glomus mosseae) were investigated on alleviating impacts drought stress Matthiola incana in a split-split-plot experiment two consecutive years. The main plot was assigned to at three levels irrigation (25%, 50%, 70%, field capacity) comparing with control (100% sub-plots AMF (0 200 g fungi pots) sub-s...

Root and shoot lead concentrations and the impact of chelating agents on these were investigated in two populations of the novel metallophyte Matthiola flavida. Plants were exposed in hydroponics to Pb(NO3)2, supplied alone, or in combination with citric acid, or EDDS. When supplied at concentrations expected to bind about 95% of the Pb in a solution containing 1-μM Pb (1000 μM citrate or 3.1 μ...

Aims The aim of the present study was to compare lead accumulation and tolerance among heavy metal hyperaccumulating and non-hyperaccumulating metallophytes. Methods To this purpose, we compared Pb tolerance and accumulation in hydroponics among calamine and non-calamine populations of Silene vulgaris, Noccaea caerulescens, and Matthiola flavida. We established the effects of Ca on Pb tolerance...
