| 摘 要： | 以6个超级小麦品种(系)为材料,通过对其剪叶、剪芒、包茎、包穗等不同处理,研究了不同光合器官对不同类型超级小麦籽粒产量的影响。结果表明,不同品种(系)不同光合器官对籽粒产量的影响不同;不同品种类型的相同光合器官对籽粒产量的影响也存在显著差异,高秆大穗型品种对穗粒重的贡献以叶片为最高,中间型品种以穗器官的贡献为高,多穗型品种则以茎鞘和贮藏物质的贡献对其穗粒重影响最大。

| Abstract: | The relationship between different photosynthetic organs and grain yield was studied through cutting the leaf,the awn and darkening the stem and the ear in six different genotype super wheats.The results were as follows.There were significantly different contributions to grain yield among different organs. The contribution of leaf photosynthesis to the grain yield of per ear was the biggest in high pole and large ear cultivars. The contribution of ear photosynthesis was biggest in middle ear cultivars,and the contribution of stem (including leaf sheath) was the highest in many ears cultivars . |
