羽裂蔓绿绒的光合特性研究

Studies on the photosynthetic characteristics of Philodendron Pluto

对观叶植物羽裂蔓绿绒的光合特性进行了研究 结果表明 :该植物叶绿素含量高 ,叶绿素a /叶绿素b比值低 ,光合 /呼吸比率高 ,适宜室内摆放 其光补偿点为 4 9 10 4 μmol·m- 2 ·s- 1,光饱和点为 34 6 914μmol·m- 2 ·s- 1

Photosynthetic characteristics of Philodendron pluto were studied The results showed that Philodendron pluto had high chlorophll content , low ratio of chlorophll a to chlorophll b, and high ratio of photosynthetic rate to respiratory rate So it was suitable for indoor ornamental plants Its light compensation point and light saturation point were 49 104 μmol·m -2 ·s -1 and 346 914 μmol·m -2 ·s -1 respectively Proposals about cultivation and management of P pluto were suggested
