摘要
本试验用^(14)C-示踪方法研究玉米灌浆期穗位叶^(14)C-光合产物在果穗籽粒之间的分配特性。结果发现,^(14)C-光合产物在果穗籽粒各行间的分配近似相等,而果穗籽粒同一行不同部位籽粒间^(14)C-光合产物分配有差别,其相对值由高到低的顺序为中部籽粒>基部籽粒>尖端籽粒。
A study on distribution of 14C-assimilates from functional leaves in grains of maize at filling stage was carried out.The results showed that distribution of 14C-photosynthetic products in grains of each row of ear were similar while in grains of different position within the same row were different.The amount of 14C-photosynthetic products in the ear was in order of middle grains>bottom grains>top grains.It was also found that 14C-photosynthet-ic products between the grains next to each other were significant different.The distribution pattern of 14C-photosynthetic products in grains of maize is also discussed.
