Effect of Street Lamp Lighting on Growth and Photosynthesis of Apricot Street Tree Fan Chunnan,Sun Yanzhao,Wang Yimeng,Lian Fangyu,Zheng Jinping (Forestry College of Beihua University,Jilin 132013,China) Abstract:According to the investigation and determination for growth,photosynthesis and chlorophyll content of apricot street tree (Armeniacavulgaris),underthecircumstanceof streetlampirradiation,theresultsshowedthat HPS lamp lighting could significantly increase new branches of the apricot street tree,its photosynthetic rate, stomatal conductance and intercellular CO concentration were bimodal type curveswith unimodal sort change of 2 light intensity.Moreover,photosynthetic rate and intercellular CO concentration exposed to the HPS lamp were
