Photoperiodic response is not restricted to flowering . 可是，光周期反应不只限于开花。
2.
The error caused by the photoperiodic induction changes along with the initiatory and terminative radiation level . and the effect of photosynthetic oscillations should be emphasized in fast measurement of photosynthesis 在诱导期间(光诱导期或光合振荡期)进行光合速率测定造成的误差与叶片光环境变化前后的强度水平及光质有关。
3.
When the change of radiation environment has instantaneous change , the photosynthetic rate ca n ' t reach the rate that it should be in the changed situation . that is called the photoperiodic induction . usually the time of the photoperiodic induction is from 3 minute to 8 minute 当叶片所处光环境的光强和光质发生瞬时变化后叶片光合速率通常都要经过3 8分钟适应才能达到变化条件下应有的光合速率值。
