哈尔滨道路绿地亮化光源对红皮云杉的影响

Effects of the Light Source of Road Greening on Growth of Picea koraiensis in Harbin

选择道路绿化生境相同、植株长势一致的红皮云杉作为样地供试材料,分别于不同颜色光源环境下,研究其净光合速率、蒸腾速率、叶绿素含量、干物重及叶色的变化,设其中无光环境为对照。结果表明,不同颜色光源以及光源距植物距离的不同对红皮云杉的光合生理影响不同,其中绿光对植株的影响最小,黄光和紫光对其影响较大。城市道路光源是影响红皮云杉生长的重要因素之一。

With Picea koraiensis as research object which in the same growing environment and with the same growing vigor,the photosynthetic rate,transpiration rate,chlorophyll cpntent,weight of dry-matter and the change of lesf color of Picea koraiensis in different lighting conditions were determined.The results showed that there had different effects in different conditions,which was different light resource and different distances.Among these different color light,green light had the least influence on Picea koraiensis,yellow light and purple light had greater influence on it.
