Functional Trait Trade-Offs for the Tropical Montane Rain Forest Species Responding to Light from Simulating Experiments

Table 1

Seedling traits, abbreviations, and units for growth and morphological analysis. These parameters were calculated following Poorter [42] and Bloor and Grubb [43].

Traits	Abbreviation	Units
Relative growth rate (ln𝑊2−ln𝑊1)/(𝑇2−𝑇1)	RGR	mg g^−1 d^−1
Relative height growth rate (ln𝐻2−ln𝐻1)/(𝑇2−𝑇1)	RGR𝐻	μm μm^−1 d^−1
Leaf mass rate (leaf dry mass/total seedling dry mass)	LMR	g g^−1
Stem mass rate (stem + petiole mass)/total plant mass	SMR	g g^−1
Root mass rate (root dry mass/total seedling dry mass)	RMR	g g^−1
Specific leaf area (leaf area/leaf mass)	SLA	cm^2 g^−1
Leaf area ratio (total leaf area/total seedling dry mass)	LAR	cm^2 g^−1

𝑊 is seedling dry mass (g), 𝐻 is seedling height (cm), 𝐴 is seedling leaf area (cm²), and 𝑇 is time (d). Subscripts refer to initial (1) or final (2) harvest.
