图1. 阔叶红松林不同树种的叶片和叶柄性状在不同植株大小(A-D)和冠层位置(大树)(E-H)间的差异。S1, 白桦; S2, 紫椴; S3, 五角枫。箱体下方不同大写字母代表性状在3个树种间存在显著差异(p < 0.05)。箱体上方不同小写字母代表给定树种的叶片和叶柄性状在不同植株大小间或不同冠层位置(大树)间存在显著差异(p < 0.05)。
Fig. 1. Variations in lamina and petiole traits among tree sizes (A-D) or canopy positions (large tree)(E-H) of the three species in a broadleaved Korean pine forest. S1, Betula platyphylla; S2, Tilia amurensis; S3, Acer pictum subsp. mono. LA, lamina area; LDM, lamina dry mass; PDM, petiole dry mass; PL, petiole length. Different uppercase letters below the boxes indicated that lamina or petiole traits significantly varied with tree species (p < 0.05). Different lowercase letters above the boxes indicated that lamina or petiole traits significantly varied with different tree sizes or different canopy positions (large tree) for a given species (p < 0.05).
