图5. 针叶年龄对红松叶形态性状相关关系的影响。不同小写字母表示不同针叶年龄斜率之间有显著差异, 且实线代表回归显著, 显著性水平均为0.05。LDMC, 叶干物质含量; ND, 针叶密度; NV, 针叶体积; SLA, 比叶面积。
Fig. 5. Effects of needle age on correlations between leaf morphological traits of Pinus koraiensis. Different lowercase letters indicate that there were significant differences between the slopes of different needle ages. The solid lines indicate that the regressions were significant (p < 0.05). LDMC, leaf dry matter content; ND, needle density; NV, needle volume; SLA, specific leaf area.
