Fig. 3 Effects of different concentrations of aqueous extract in Populus cathayana leaffall on seed germination and length of stem and root of P. cathayana seedlings. Different letters above the bars represent significant differences at p = 0.05 according to Duncan’s test. The different letters comparison was restricted by the same alphanumeric classification system. Each value is the mean ± SE.
