选用英国pp-system公司生产的CIRAS-1型便携式光合测定仪，测定红富士苹果的秋季光合特性。研究得出，礼泉短富在8月份的叶片光合速率日变化为单峰曲线，光合速率日平均值分别比长富二号和皇家嘎拉高50.11%和72.69%，树冠中层叶片光合强度最高，上层次之，下层最低；不同枝条类型中健壮生长枝、长枝和中枝光合速率较高，短枝光合速率较低，健壮生长枝中部的叶片光合速率高。西北林学院学报21卷第5期郑文君等红富士苹果秋季叶片光合特性研究初报
- Abstract:
-
Photosynthesis properties of Fuji apple tree in the autumn were studied.The results indicated that diurnal variation of photosynthesis rate was an one peak curve pattern.The everage photosynthesis rates were 50.11% and 72.69% higher than those of Changfu and Royal Gala respectively;the intensity of photosynthesis was the highest in the middle layer of the crown,than in the top layer,and lowes in the bottom layer.Among different types of branches,higher photosynthesis rates were in vigorous growing branches and long ones,lower in short branches.The photosynthesis rate was higher in the middle part within the vigorous growing branches.
