| The contents of chlorophyll components and activity of SOD and POD of 17 species in Gramineae, Leguminosae, Vitaceae and Bignoniaceae generally applied in ecologic greening of abandoned mines were determined. The results were stated as follows: The maximum contents of chlorophyll a, chlorophyll b, carotenoids and total chlorophyll were Lespedeza bicolor, Cynodon dactylon, C. dactylon (for forage) and C.dactylon, which were 12.46, 1.10, 0.32 and 3.63 mg/gFW, respectively. The lowest contents of the four indexes were Amorpha fruticosa, Parthenocissus tricuspidata (ternate leaf), Miscanthus sinensis and A.fruticosa, which were 1.10, 0.48, 0.08 and 1.70 mg/gFW. C.dactylon (for forage) and P.tricuspidata (ternate leaf) possessed the first and last place for the chlorophyll a/b value. About the activity of SOD and POD, Millettia reticulate and M.sinensis had the maximum activity, which could reach 477.00U and 217.20U. |
