However, instantaneous measures of leaf-level gas exchange often fail to mirror the behavior of cover or biomass (Givnish 1988; Chiariello et al. 1989; Villar et al. 1998) and are quite sensitive to transient and local moisture, temperature, and light conditions (Field et al. 1989), masking ecotype differences.
Both programs returned effectively identical measures of leaf area, with an R2 value of 0.99.
Leaf carbon and oxygen isotope measurements reflect important characteristics of gas exchange at leaf level and integrate over the lifetime of the leaf.
Figure 12 Mean leaf transpiration rate for the different treatments, measured at the individual leaf level under different climatic conditions (air temperatures and VPD).
Perimeter per leaf area⋅Feret's diameter is a unitless measure of leaf lobedness [e.g., 41] that influences the leaf radiation balance [42].
At the leaf level, I measured relative water content (RWC) and leaf toughness were measured.
We say that a subtree (t_mathrm{leaf}) is a leaf level subtree of a syntax tree (T_s) if (t_mathrm{leaf} sqsubseteq T_s) and both arguments of an operation in a root node of (t_mathrm{leaf}) are data containers.
Furthermore, the ecophysiological adaptation at the leaf level was assessed in terms of net photosynthesis and leaf transpiration.
The leaf level is denoted as level which corresponds to the height of the tree.
In order to find the parameters to constrain a multi-leaf model, I am measuring leaf-level gas exchange in the canopy.
The dataset includes field measured leaf-level directional-hemispherical reflectance/transmittance together with seven important leaf traits [total chlorophyll (chlorophyll a and b), carotenoids, mass-based nitrogen concentration (Nmass), mass-based carbon concentration (Cmass), and leaf mass per area (LMA)].
