图3. 中亚热带同质园8个树种成熟叶和衰老叶之间微量元素的含量变化(衰老叶-成熟叶) (平均值±标准误, n = 3)。DBL, 落叶阔叶树种(n = 9); EBL, 常绿阔叶树种(n = 12); EC, 常绿针叶树种(n = 3)。PM, 马尾松; CCam, 樟; CCar, 米槠; MM, 醉香含笑; ED, 杜英; LF, 枫香树; SS, 无患子; LCh, 鹅掌楸。不同小写字母表示不同树种间差异显著(p < 0.05)。

Fig. 3. Changes in the content of trace elements between green and senescent leaves of eight tree species in the common garden in mid-subtropical region (nutrient content in green leaves minus that in senescent leaves) (mean ± SE, n = 3). DBL, deciduous broadleaf species (n = 9); EBL, evergreen broadleaf species (n = 12); EC, evergreen coniferous species (n = 3). PM, Pinus massoniana; CCam, Cinnamomum camphora; CCar, Castanopsis carlesii; MM, Michelia macclurei; ED, Elaeocarpus decipiens; LF, Liquidambar formosana; SS, Sapindus saponaria; LCh, Liriodendron chinense. Different lowercase letters meant significant difference among tree species (p < 0.05).
