图2. 三个种源红松种子在不同透光林分下不同季节的自然萌发率(平均值±标准误)。红松种子在春季均未萌发, 因此仅显示夏、秋季数据。不同大写字母表示同一林分不同季节间差异显著(p ≤ 0.05), 不同小写字母表示同一季节不同透光林分间差异显著(p ≤ 0.05)。
Fig. 2. Germination percentage of Pinus koraiensis seeds from three provenances under different light conditions between different seasons (mean ± SE). The seeds did not germinate in spring, thus only summer and autumn data were displayed. Different uppercase letters indicate significant differences between different seasons in the forest stands with the same light transmittance (p ≤ 0.05). Different lowercase letters indicate significant differences between forest stands with different light transmittances in the same season (p ≤ 0.05).
