Characteristic of gas exchange and chlorophyll fluorescence parameters in leaves of Lespedeza davurica

摘要

This paper tests and analyzes the net photosynthetic rate ( Pn), transpiration rate ( T r), stomatal conductance ( Gs), intracellular CO2 concentration ( Ci), minimal fluorescence yield ( Fo), maximum fluorescence yield ( Fm), variable fluorescence yield ( Fv ) and electron transport rates ( ETR ) to reveal the physiological and ecological characteristics of Lespedez a davurica.
