图4. 慈竹不同发育阶段的笋体、竹箨和成熟叶片的光合速率、蒸腾速率、气孔导度(平均值±标准差)。I1, 节间伸长期; I2, 节间完全伸长期; I3, 节间成熟期; L, 竹子的成熟叶片; S1, 幼嫩箨鞘; S2, 成熟箨鞘; SL1, 幼嫩箨叶; SL2, 成熟箨叶。不同小写字母表示笋体、竹箨、成熟叶片之间差异显著(p < 0.05)。
Fig. 4. Stomatal conductance (Gs), net photosynthetic rate (Pn), transpiration rate (Tr) of shoot body, bamboo sheath and mature branch leaf at different developmental stages of Bambusa emeiensis (mean ± SD). I1, elongating internode; I2, fully elongated internode; I3, mature internode; L, mature branch leaf; S1, young culm sheath; S2, mature culm sheath; SL1, young sheath leaf; SL2, mature sheath leaf. Different lowercase letters indicate significant differences among shoot body, bamboo sheath and mature branch leaf (p < 0.05).
