日本蔬菜与观赏作物研究站利用~(14)C示踪技术探索设施栽培条件下温度对番茄光合产物的转输和分配的影响,温度自3℃升高到33℃,光合产物的转输速度加快,如夜间温度较低(8℃),白天的光合产物中有相当大的一部分滞留在叶片中,对翌日的光合作用产生不良影响,如夜间温度较高(>13℃),光合产物的转输速度加快,但因呼吸作用加强而消
At the Japan Vegetable and Ornamental Crop Research Station, the effect of temperature on the translocation and distribution of photosynthate in tomato plants under greenhouse cultivation was explored using ~ (14) C tracer technique. The temperature of photosynthate was increased from 3 ℃ to 33 ℃, If the temperature is lower at night (8 ℃), a significant part of photosynthate during the day stays in the leaves and adversely affects the photosynthesis of the next day, such as higher nighttime temperature (> 13 ℃), photosynthate Transfer faster, but because of enhanced respiratory elimination
