项目摘要

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.

分别在连续光照处理5、30、180、360、420、600和780min后进行以下实验。将~(11)CO_2气体示踪剂注入叶片，用叶柄测定碳从叶片到果实的转移。光处理5min和30min的固碳量比其他处理少。结果表明，在预处理5min和30min时，碳转运量和碳转运率均较低。据报道，光合作用速率与叶片的碳输出速度呈正相关。上述结果支持了这一报道。另一方面，在光照处理780min的情况下，加入11CO2气体后不久的测量条件向黑暗转变。此时，固碳量虽不低，但暗条件下碳转运的速度和体积都大大降低。夜间条件下的碳转移需要更多的考虑。
