Description
Comprehensive measurement of leaf morphological, physiological, and chemical traits including stomatal conductance, leaf mass per area, nitrogen content, and spectral properties to characterize plant functional strategies.
Typical Equipment
- steady-state porometer (LI-COR, LI-1600M)
- flatbed scanner (Canon, LIDE 220)
- digital balance
- drying oven
- elemental analyzer (Sercon, PDZ Europa ANCA-GSL)
- isotope ratio mass spectrometer (Sercon, PDZ Europa 20-20)
- field spectroradiometer (ASD, FieldSpec HandHeld 2)
- brightfield microscope (Leica, DM750)
Output Measurements
- stomatal conductance
- leaf mass per area
- leaf dry matter content
- nitrogen content
- δ¹³C
- leaf absorptance
- stomatal distribution
