图8. 遮阴转入全日光后叶片快速荧光诱导动力学曲线W_O-J和ΔW_O-J的变化(时间坐标为线性形式)。W,K点(100 μs)处的特征位点。day 0、Sunlight-day 1、Sunlight-day 2和Sunlight-day 3分别表示转入全日光前和转入全日光后1、2、3天。不同字母表示差异显著( p< 0.05)。

Fig. 8. Changes in rapid fluorescence induction kinetic curves (W_O-J and Δ W_O-J) in leaves of Panax notoginseng transferred from a shade environment with 10% transmittance to full sunlight. The abscissa is plotted on a linear time scale. W,the characteristic point at 100 μs (K point). Day 0, Sunlight-day 1, Sunlight-day 2, Sunlight-day 3 represent the exposure to low light, and the transfer to full sunlight for one, two and three days. Different lowercase letters indicate significant differences ( p< 0.05).
