摘要:
采用光学显微镜和扫描电镜相结合,对山东丹参、丹参、南丹参发育良好成熟的花粉粒进行比较观察。结果表明:花粉粒形态、大小和外壁网状雕纹特征均具有较显著区别,首次为山东丹参新种积累孢粉学资料、确立其在植物分类学上的地位以及研究其种质,提供花粉形态的重要依据;丹参和南丹参花粉粒形态特征及外壁网状雕纹与前人报道相一致,为揭示山东丹参与丹参、南丹参之间的亲缘关系及种间分类鉴定提供了孢粉学依据;也为山东丹参药用植物新资源的开发提供科学依据。
Abstract:
Welldeveloped mature pollen grains of Salvia shandongensis,S.miltiorrhiza and S.bowleyana are examined by using light microscope and scanning electron microscope. The results indicated that there were clear distinctions among the shape,size and exine sculpture of S.miltiorrhiza plants’ pollen. This study not only first provided the important pollen morphological basis for accumulating the palynology information for S.shandongensis new species,establishing its position in plant taxonomy and researching its species quality; pollen grains morphological features and exine sculpture of S.miltiorrhiza and S.bowleyana were consistent with previous reports and provided the palynology information for revealing their genetic relationships of S.shandongensis,S.miltiorrhiza and S. bowleyana and distinguishing their species taxonomy,but also provided scientific basis for the development of new medicinal plant resources of S.shandongensis.
