WebMar 15, 2016 · Specific leaf area (SLA) of individual leaves or needles was calculated as a ratio of foliage area and dry mass. A further 80 beech and 100 spruce trees were selected from each stand for destructive sampling in early September 2011 (BiomTrees thereafter). All tree compartments with the exception of fine roots thinner than 2 mm were harvested.

Leaf mass per area (LMA) is its inverse and can mathematically be decomposed in two component variables, leaf thickness (LTh) and leaf density (LD): [4] Typical units are g.m −2 for LMA, µm for LTh and g.ml −1 for LD. Both SLA and LMA are frequently used in plant ecology and biology. See more Specific leaf area (SLA) is the ratio of leaf area to leaf dry mass. The inverse of SLA is Leaf Mass per Area (LMA). See more Normal ranges of SLA and LMA are species-dependent and influenced by growth environment.

WebGiven the total leaf mass per ground area in a laterally homogeneous vegetative canopy (of a crop, even-aged stand, or clonal plant), how should this mass be distributed with depth to maximize the canopy's photosynthetic rate? That is, how should the specific leaf mass, m (mass per unit of leaf area), vary with cumulative-leaf-area index, L?
