Burma reed (Neyraudia reynaudiana) is a perennial grass which has the capacity of strong tolerance to drought

leanness

high temperature

and acid. It is a pioneer plant in natural vegetation restoration in the deserted area resulted from water erosion

mining area

stone pit

and slope. In order to explore the feasibility of ecological restoration with burmareed in various mining areas and the heavy metal contaminated area

germination ability of burma reed seed stressed by different concentrations of Hg2+

Cr6+

Cd2+

Pb2+

Zn2+

and Cu2+

as well as different pH values was studied by labg ermination test . Results showed that burma reed seed can well germinate between pH 5.0~ 9.0. Inhibiting effect of the heavy metals on burmareed seeds increased with increase of heavy metal concent ration. The order of the heavy metals

by the lowest concent ration which leaded to inhibition

was Cd2+ < Cu2+ < Hg2+

Zn2+ and Cr6+ < Pb2+. The concent rations of the heavy metals which affected obviously burma reed seed vigor were lower than the concent rations which affected obviously burma reed seed germination percentage

germination vigor

and germination index . This indicates that seedling is more sensitive to the heavy metals than germination.
