Fig. 3From: Effects of defoliation modalities on plant growth, leaf traits, and carbohydrate allocation in Amorpha fruticosa L. and Robinia pseudoacacia L. seedlingsNet photosynthetic rate of remaining leaves (AREM) of Amorpha fruticosa (a, b) and Robinia pseudoacacia (c, d) under different defoliation treatments. The values shown are mean ± SE (n = 4). The asterisk represents the significant difference (p < 0.05) between the control group and the defoliation group; CK, no defoliation; TD, defoliation of the top down 50% of the crown; BU, defoliation of the bottom up 50% of the crown. CK in a and c, upper leaves in the crown were measured, whereas b and d concerned lower leavesBack to article page
