Table 5 Effects of within-gap position and tree species on the concentrations of NSCs (soluble sugar, starch, and total NSC) and the ratios of leaf NSCs to stem NSCs in 1-year-old sprouts and 2-year-old sprouts

From: The effects of stump size and within-gap position on sprout non-structural carbohydrates concentrations and regeneration in forest gaps vary among species with different shade tolerances
