| 摘 要： | 比较分析了荔枝花性决定中碳氮化合物的动态变化。结果发现：C/N较大有利于雄蕊分化,反之则有利于雌蕊分化;氨基酸含量较高有利于雌蕊分化,雄蕊的氨基酸含量仅为雌蕊的一半。脯氨酸与花粉育性存在着密切相关关系。另外,探讨了雌蕊或雄蕊败育的生理意义,在长期的进化中,败育的雌蕊或雄蕊“废物”重新被利用,为同一花中迅速发育的雌蕊或雄蕊提供能量和物质的需求,表5参13。 |

| Abstract: | By comparing and analyzing the dynamic changes of carbonitride in during the floral sex determination litchi,it was found that higher C/N and lower amino acid content were beneficial to androecium differentiation; conversely, lower C/N and higher amino acid content were adequate for gynoecium differentiation; the amino acid content in androecium was only half of that in gynoecium; proline was associated with pollen developmental capacity. Besides, the physiological significance of androecium or gynoecium abortion was discussed. In the evolution of long period of time, the aborted androecium or gynoecium "scrap" could be used by the same flower to offer energy and substance for flower development. Tab 5, Ref 13 |
