| 摘要: |
| 芒果花药发育中,花药药壁体细胞中淀粉粒多糖和脂滴类物质一直很少,仅药室内壁细胞中有零星淀粉粒分布。到二胞花粉早期,花粉营养细胞中的大液泡消失,开始积累淀粉粒。芒果成熟花粉中储存营养物质主要是淀粉粒,而脂类物质一直很少。 |

| Abstract: |
| The distribution of polysaccharides and lipids was studied during the anther development of Mangifera indica. Only a few starches and lipids appeared in endothecium cells of anther wall during anther developemnt. After mitosis of microspores,starches began to accumulate in the vegetative cell of bicellular pollen. At anthesis,mature pollen grains accumulated many starches as storage nutrition. |
