Fig. 4From: Responses to defoliation of Robinia pseudoacacia L. and Sophora japonica L. are soil water condition dependentComparisons of NSC concentration in leaf (a), stem (b), and root (c) of R. pseudoacacia and S. japonica from different water and defoliation treatments (mean ± SE, n = 5) at the end of the experiment. Different uppercase and lowercase letters denote significant differences in each species at p ≤ 0.05 by Duncan’s test, respectively. W1, W2, and W3: 75%, 55%, and 35% of field capacity. D0, D1, and D2: control, 50% defoliation, and 100% defoliation. Asterisks indicate significant differences between species in each drought and defoliation treatment separately with independent sample t-test: **p ≤ 0.01, *p ≤ 0.05Back to article page
