[Physiology and development of two Roegneria kamoji populations stressed by copper]
Abstract:
Roegneria kamoji grown copper tailings had weak stem, short height, and thick leave color, while its counterpart on normal soil was the opposite. Exposed to copper, R. kamoji had a decreased chlorophyll content. A certain concentration of copper could promote the seed germination of R. kamoji, and the extract of copper tailings did not decrease the seed germination rate, but deferred the germination. Root growth test indicated that when the concentration of copper was 0.125 mg.L-1, the rooting of R. kamoji was promoted. If the concentration was more than 0.25 mg.L-1, the rooting was inhibited significantly. R. kamoji colonized on normal soil wase more sensitive to copper than that on Cu-polluted soil.
