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 (ln⁡W2 − ln⁡W1)/(T 2−T 1)	RGR	mg g−1 d−1
Relative height growth rate (ln⁡H 2 − ln⁡H 1)/(T 2 − T 1)	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	cm2 g−1
Leaf area ratio (total leaf area/total seedling dry mass)	LAR	cm2 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.
