Consequences between leaf optical property (i.e., reflectance and transmittance spectra) and leaf biochemical/anatomical properties are crucial in understanding the leaf-level light utilization and also in realizing remote sensing of canopy ecophysiology. However very few studies have focused on the leaf optical property in studies on photosynthesis or plant productivity. In order to reveal the relationship between optical property and the ecophysiological characteristics at single leaf level, we measured reflectance and transmittance spectra from 350 to 1600 nm, photosynthetic traits (Vc_max and J_max), leaf mass per area, contents of pigments (chlorophyll, carotenoide, anthocyanin) and water content for eight species of various functional types; canopy tree species (Quercus crispula and Betula ermanii), understory species of a deciduous forest (Sasa senanensis and Hydrangea paniculata), dominant species in grassland (Miscanthus sinensis, Imperata cylindrica and Solidago altissima) and a crop (Oryza sativa). By analysing these data across the species and throughout the seasons, we will discuss the specific spectra for detecting the ecophysiological characteristics in terrestrial vegetation.
