Supply and accumulation of metals in two Egyptian desert plant species growing on wadi-fill deposits

Sandy soils of the wadisin the Eastern Desert of Egypt have a poor retentive capacity for metals. The contents of Ca, Mg, K, Na, Fe, Al, Mn, Co, Ni, Cu and Zn in 37 soils from this area were highly variable. The metal contents of two dominant plant species of the Eastern Desert ( Senna alexandrinaan...

Summary:Sandy soils of the wadisin the Eastern Desert of Egypt have a poor retentive capacity for metals. The contents of Ca, Mg, K, Na, Fe, Al, Mn, Co, Ni, Cu and Zn in 37 soils from this area were highly variable. The metal contents of two dominant plant species of the Eastern Desert ( Senna alexandrinaand Cleome droserifolia) showed no correlation with soil metals. Metals accumulated in the leaves, with Cleomehaving overall higher contents of Fe, Al, Mn, Co, Ni, Na and Si than Senna, even though Cleometended to grow in soil with low contents of these metals.
