《菊科紫菀族花粉的形态结构与系统演化》对菊科紫菀族的36属350种植物花粉进行了光学显微镜、扫描电镜与透射电镜的观察和研究。根据花粉的形状、大小、萌发器官的类型、外壁纹饰和内层结构,首次将紫菀族花粉划分为40个类型,其中很多类型为第1次报道。同时,利用Hennig86程序,对紫菀族40个花粉类型进行了分支分析,结果表明紫菀族分为田基黄亚族(Grangeinae)和紫菀亚族(Asterinae)两个亚族较为合理,从花粉角度证实了Jeffrey关于紫菀族次级划分的论断,并详细讨论了各类型之间的系统演化关系。在此基础上,将所获得的孢粉学资料和植物地理分布结合起来,探讨了紫菀族植物的起源地点和时间,以及多样化中心、分布式样及迁移路线。提出了各类型花粉进化程度的判别标准和完整的分类系统,特别是将花粉形态结构的形成与生境因子联系起来,首次构建了花粉生态类型的概念。最后,按照孢粉特征和植物体形态特征相结合的原则,对紫菀族各重要属、种的分类提出了一系列新的处理意见。《菊科紫菀族花粉的形态结构与系统演化》包括紫菀族植物36属350种(包括变种)花粉形态描述,花粉类型检索表,地理分布图12幅,光学显微镜、扫描电镜和透射电镜图版(照片)179面。

The tribe Astereae (Compositae) is worldwide in distribution but with marked concentration in southwestern North America, South America along the Andes, South Africa, Australia and New Zealand, and includes about 170 genera and 2800 species . There are 28 genera, 224 species of Astereae in China, most of which are distributed in steppe areas in the northwest of China, covering an area of Xinjiang, the Inner Mongolia, southeastern Tibet, northwestern Yunnan, Shichuan and Himalaya area .

The plants of Astereae have been diversified strongly and had complicated intrasubtribal and intergenera relationships, raising difficulty in subtribal classification, The existing subtribal classification was provided by Bentham (1873a) who classified Astereae into six subtribal, e.g. Solidagininae, Grangeinae, Bellidinae, Asterinae, Conyzinae and Baccharidinae, meanwhile, he also pointed out that this tribe was "not being divisible into district subtribes", so the subtribal classification that he actually proposed must be regarded as provisional.
