简介:
LCi-T 便携式光合仪是最幼巧、轻便的便携式光合作用测定仪,用以丈量植物叶片的光合速度、蒸腾速度、气孔导度蹬纂植物光合作用有关的参数。仪器利用IRGA(红表气体分析)道理,精密丈量叶片表表CO2浓度及水分的变动情况来调查叶片与植物光合作用有关的参数。特殊的设计可在高湿度、高尘;肪呈褂。既可在钻研中使用,又是很好的讲授仪器。

典型利用
Leaf life span optimizes annual biomass production rather than plant photosynthetic capacity in an evergreen shrub, Marty C. et al. 2010, New Phytologist, 187(2): 407-416

本文钻研了Rhododendron ferrugineum(高山玫瑰杜鹃,杜鹃属模式种)净光合能力与叶片寿命的关系,发现有更多较老叶片的种群其光合能力更强(图中深色区域为一年叶片和二年叶片)。
