Abstract:
Taking Fragaria orientalis，Viola variegata， Potentilla flagellaris， Potentilla anserina， Papaver nudicaule， Oxytropis coerulea， Oplismenus undulatifolius， Clematis heracleifolia， Vicia unijuga and Dicranostigma leptopodum as test materials.In the experiment,diurnal change of photosynthesis,light response curves and CO2 response curves of ten species of wild ground cover plants were researched.The results showed that the dirunal changes of the net photosynthetic rate of both Fragaria orientalis and Dicranostigma leptopodum were unimodal curves，but the other of eight species displayed twin peaks with an obvious midday depression.Both the light saturation point((9.64±0.525) μmol?m-2?s-1) and the CO2 compensation point((67.72±4.567) μmol?m-2?s-1) of Oplismenus undulatifolius were the lowest.All these showed that Oplismenus undulatifolius was the repersentatiive shade plant.The light compensation point((74.21±1.065) μmol?m-2?s-1) of Oxytropis coerulea was much higher than the other species,and the CO2 compensation point((107.94±9.345) μmol?m-2?s-1) of Dicranostigma leptopodum was the highest，both of these species showed the phototaxis.
