Table 2.
Means and standard deviations for mass and nonstructural carbohydrate (NSC) components of seedlings sampled before treatment. a) NSC concentration, b) Starch concentration, c) Soluble sugar concentration d) Plant mass and age. Species abbreviations in Table 1. * Values in gray for FA were estimated from linear models because total plant mass was not measured for the first harvest and we could not calculate them directly
