| 摘 要： | 通过对湖南省浏阳市周洛村桂花峡两次实地调查, 观察分析了桂花(Osmanthus fragransLour. ) 群落所处的自然地理条件和其群落学特点, 在此基础上对桂花居群的生物学特征, 特别是花形态变异进行观察记录。结果显示桂花峡内的桂花花色以浅黄色和乳黄色为主, 偶有橙黄色和雪白色花个体; 花有两性花和雌蕊花柱退化的单性雄花两种类型, 居群内桂花个体间的花形态变异丰富, 具有天然更新能力。 |

| Abstract: | The physiographical factors, the community's components and morphological characteristics of sweet osmanthus(Osmanthus fragrans) community were studied by two surveys at Zhouluocun in Hunan. Based on the field investigation, the biological characteristics of sweet osmanthus population were analysed; interestingly, morphological variations of flower were found. The results show that the color of sweet osmanthus corolla is mainly either light yellow or milk yellow, but occasionally aureate or snow-white individuals can be found due to genetical variation in this Zhouluocun community. Flower types of sweet osmanthus are bisexual flower or unisexual male flower due to the degeneration of pistil. Our data demonstrate that there are abundant morphological variations and successful regeneration in the natural population of sweet osmanthus. |
