| 摘 要： | 应用扫描电镜,对野生浙江红山茶11个类型花粉的形态进行了观察。结果表明:其花粉粒为长球形或超长球形,具3孔沟,大小为极轴长38.6～59.8μm、赤道轴长15.4～38.1μm;根据穿孔大小及数量、脊的明显度将其花粉外壁纹饰分为皱波状、皱波状-有穿孔、皱波-颗粒状和网状4种类型;花粉形态对浙江红山茶类型划分有很大价值,依据其形态编制了类型分类检索表。最后,对11种类型浙江红山茶花粉形态的分类及演化趋势进行了讨论。

| Abstract: | The pollen morphology of eleven types of wild Camellia chekiangoleosa were observed under scanning electron microscope(SEM).The results showed that pollen grains were prolate or perprolate in shape with three colporate.The length between poles varied from 38.6 to 59.8 μm and diameter of the equator ranged 15.4~38.1 μm.Based on the size and quantity of porus and ridges patency,the surface ornamentation of Camellia chekiangoleosa could be divided into four groups:regulate,regulate-porus,regulate-granulate and spinulate.The pollen morphology was valuable traits in types classification of Camellia chekiangoleosa.So a retrieval key was established according to pollen morphology.Finally,the classify and evolution of eleven types of Camellia chekiangoleosa were discussed. |
