The following experiments was done after 5, 30, 180, 360,420, 600 and 780 min of continuous light pretreatment. The 11CO2 gas tracer was fed to the leaf and carbon translocation from leaf to fruit was measured with PETIS. The amount of carbon fixation was fewer of 5 and 30 min of light pretreatment than that other minutes pretreatment. As a result, volume and velocity of carbon translocation became low in 5 and 30 min pretreatment. It has been reported that the positive correlation between photosynthetic rate and the velocity of carbon export from the leaf. The above result supported this report. On the other hand, in the case of 780 min of light pretreatment, the measurement condition soon after fed 11CO2 gas shift to darkness. At this time, although the amount of carbon fixation was not low, the velocity and volume of carbon translocation under dark condition were greatly decreased. The carbon translocation under the night condition require greater consideration.

以下实验是在连续光预处理5、30、180、360,420、600和780分钟后进行的。将 11CO2 气体示踪剂注入叶子，并使用 PETIS 测量从叶子到果实的碳转移。光预处理5分钟和30分钟的固碳量比其他分钟预处理少。结果，在 5 分钟和 30 分钟预处理中，碳易位的体积和速度变低。据报道，光合速率与叶片碳输出速度呈正相关。上述结果支持了本报告。另一方面，在光预处理780分钟的情况下，在通入11CO 2 气体后不久测量条件就转变为黑暗。此时，虽然碳固定量不低，但黑暗条件下碳转位的速度和体积却大大降低。夜间条件下的碳易位需要更多的考虑。
