摘　　要：文章对女贞、南酸枣、枫香、海棠这4种阳生乔木一年苗进行试验。叶形态指标、叶绿素等试验表明:当光照度大于植物光饱和点时,植物出现光抑制现象;当光照度远低于光饱和点时,园林夜景植物也会发生光抑制现象;当光照度低于4 900 lx时,叶片叶形态指标都明显增加;当光照度高于4 900 lx时,植物出现光抑制现象。This paper carries out tests on one-year seedlings of four kinds of heliophilic arbors of Ligustrum lucidum,Choerospondias axillaris,Liquidambar formosana and Malus spectabilis.Leaf morphological index,chlorophyll and other tests show that when the illuminance is greater than the light saturation point of the plant,the plant appears photoinhibition phenomenon;when the illuminance is far lower than the light saturation point,the garden nightscape plants will also appear photoinhibition phenomenon;when the illuminance is lower than 4900 lx,the leaf morphological index increases signifi cantly;when the illuminance is higher than 4900 lx,the plant appears photoinhibition phenomenon.
