Table 2 Abbreviations and description for the traits in the text
Acronym | Leaf and stem traits | Description |
|---|---|---|
LMA | Leaf mass per area (g/cm²) | The ratio of specific leaf weight to total leaf area. |
LA | Total leaf area (cm2) | The sum of all leaf areas on the entire branches. |
La | Single leaf area (cm2) | Average of the upper leaf area of the entire branches. |
LT | Leaf thickness (cm) | The thickness of the leaf cross-section. |
ET | Epidermal thickness (µm) | The thickness of the outermost part of the leaf. |
MT | Mesophyll thickness (µm) | The thickness between the upper and lower epidermis, include the palisade tissue and the sponge tissue (Psammophyte sponge tissue is specialized as a water-storing tissue composed of large parenchyma cells [52,53,54]). |
SD | Stomata density (mm-²) | The number of stomata per unit area. |
SL | Stomata length (µm) | Average of the maximum length of the stomata. |
WD | Wood density (g/ml) | The ratio of stem segment mass and volume. |
SA | Sapwood area (cm2) | The cross-sectional area at the very bottom of the branches. |
CT | Cortical thickness (µm) | The thickness of the outermost part of the mature stem. |
XS | Xylem area to sapwood area (%) | The ratio of stem xylem area to stem cross-sectional area. |
PS | Pith area to sapwood area (%) | The ratio of stem pith area to stem cross-sectional area. |
VD | Vessel density (mm-²) | The number of vessels per unit area. |
VS | Vessel size (µm) | Average of the maximum length of the vessel. |
