废弃矿山生态复绿常用17种植物叶绿素含量及SOD和POD活力测定

选用废弃矿山绿化常用的禾本科、豆科、葡萄科和紫葳科共17种为实验材料,测定了其叶绿素各组分含量及超氧岐化酶(SOD)和过氧化物酶(POD)活力,结果表明:叶绿素a、b类胡萝卜素和叶片色素总质量比最高的植物分别是胡枝子、狗牙根、牧草型狗牙根和狗牙根,其质量比分别为2.46 mg/g.FW、1.10 mg/g.FW、0.32 mg/g.FW和3.63 mg/g.FW;4者质量比最低的是紫穗槐、三出叶爬山虎、芒和紫穗槐,为1.10 mg/g.FW、0.48 mg/g.FW、0.08 mg/g.FW和1.70 mg/g.FW。ωa(叶绿素a)/ωb(叶绿素b)最高的是牧草型狗牙根,为3.03 mg/g.FW,最低的是芒,仅为1.65 mg/g.FW。POD和SOD活力最高的是网络崖豆藤和芒,达477.00 U和217.20 U,最低的是牧草型狗牙根和紫穗槐,仅为24 U和39.43 U。

The Contents of Chlorophyll Components and Activity of SOD and POD of 17 Species Generally Applied in Ecologic Greening of Abandoned Mines

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/g·FW,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/g·FW.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.
