| 摘 要： | 应用~(14)C放射性同位素示踪方法测定大豆的光合速率。结果表明,复叶的3个小叶间和小叶各部位间的光合速率差异不显著;叶正面的光合速率比叶背面的光合速率高24—29％;大豆没有发现午睡现象;盛花期至结荚期的光合速率高,大豆光合速率与根瘤固N之间有密切相关,并对籽实产量有重要影响。

| Abstract: | Measuring the photosynthetic rate of soybean by 14C radioactive isotopic tracering was undertaken. The results showed that, 1. There were significant difference of photosynthetic rate among 3 leaflets of a trifoliolate leaf and among different parts of a leaflet. 2. The pho-tosynthetic rate of upper surface was by 24-29% higher than the lower surface. 3. There were significant difference of photosynthetic rate among leaves on different nodes. 4. There was no "noon-nap" exhibited in soybean photosynthesis. 5. The maximum photosynthetic rate was discovered during fullbloom to middle pod-filling stage. 6. There were significant relation between the photosynthetic rate and N-fixingability and they both affected the seed yield of soybean. |
