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。

关 键 词:玉米    功能叶    ~(14)C-同化产物    运转与分配

TRANSPORTATION AND DISTRIBUTION OF ~(14)C-ASSIMILATE FROM FUNCTIONAL LEAVES IN THE DEVELOPMENT OF GRAINS OF MAIZE
Abstract: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.
Keywords:14C-photosynthetic products  transportation and distribution  maize grain  functional leaves
