摘要
研究了 3种遮光处理对室内悬垂植物绿萝、口红花和天竺葵生长的影响并对其光合特性进行测定分析。结果表明:5 0 %～ 75 %遮荫,绿萝的平均枝长和叶片数有明显增长,75 %遮荫利于口红花的生长,天竺葵在 5 0 %遮荫条件下,新枝数和叶片数明显较其他处理的增加量多。遮荫使 3种室内植物叶绿素含量增加。天竺葵的耐荫性较绿萝和口红化差。
Influence of shading treatment on the growth and photosynthetic characteristics of three ornamental plants is studied primarily in this paper.The results show that the average length of branches and leaf number of Scindapsus aureus (Rhaphidophora aurea) increased remarkably for 50%～75% shading treatment,75% shading is favorable to the growth of Aeschynanthus pulcher ,and the number of branches and leaves of Pelargonium peltatum is more than that of the others.Shading results in more chlorophyll content.The adaptability to shading of Pelargonium peltatum is inferior to that of Scindapsus aureus (Rhaphidophora aurea) and Aexchynanthus pulcher.
