在扫描电子显微镜下观察了5种铁兰属植物花粉的微形态,结果表明:铁兰属植物花粉的微形态具有一定的共性,即都具有1个萌发沟,花粉外壁都具网纹纹饰,说明铁兰属植物是自然类群中较进化的类群.根据花粉形状的不同,推测松萝铁兰(Tillandsia usneoides)可能是铁兰属中较原始的种.铁兰属不同种在花粉大小、网孔形状、网孔间距等情况有较大的差异,这些花粉表面微观形态的差异可为种的分类提供依据.

Pollen morphology of 5 species in genus Tillandsia were observed by standard electronic modules (SEM). The results revealed the common features in their shape: i.e.1-colporate and reticulate exine. All these showed that genus Tillandsia plants were more advanced in evolution than the other species within the same taxa. According to the unique pollen shape, we proposed that Tillandsia might be a relatively originate species in genus Tillandsia. The pollen size, mesh shape and space between meshes were different. Pollen morphology was one of major references in plant taxonomy.
