山西霍山罂粟科植物花粉形态

Study on the pollen morphology of Papaveraceae of Huoshan, Shanxi

利用光学显微镜和扫描电子显微镜对山西霍山罂粟科白屈菜属白屈菜、紫堇属延胡索、角茴香属角茴香、秃疮花属秃疮花 4种的花粉形态进行了观察和比较研究 ,以上 4种花粉差异大。角茴香花粉粒近球形 ,具合沟 ;延胡索花粉粒长球形 ,表面纹饰较光滑 ;白屈菜花粉粒长球形或近球形 ;秃疮花花粉粒近球形。角茴香花粉表面纹饰为刺状纹和细网状纹的复合纹 ,白屈菜花粉表面纹饰为细网状纹和颗粒状纹的复合纹 ,秃疮花花粉表面纹饰为细颗粒状纹。延胡索、白屈菜、秃疮花花粉粒的萌发沟均为三沟 。

Pollen morphology of 4 species( Chelidonium majus L., Corydali yanhusuo W.T.Wang., Hypecoum erectum L., Dicranostigma leptopodum (Maxim.)Fedde)of Papaveraceae of Huoshan,Shanxi,was examined by means of LM and SEM. The difference of pollen morphology of 4 species is evident. The pollen grain of H.erectum L. is sub spheroidal,have syncolpate. The pollen grain of C.yanhusuo W.T.Wang is prolate. The ornamentation of the exine is nearly smooth. The pollen grain of Ch.majus L. is prolate or sub spheroidal. The pollen grain of D.Ieptopodum (Maxim.)Fedde is sub spheroidal. The exine ornamentation of H.erectum L. is composed of spinulate and finely reticulate;The exine ornamentation of D.Ieptopodum (Maxim.)Fedde is finely granulate;The exine ornamentation of Ch.majus L.is composed of finely reticulate and granulate .They( C.yanhusuo W.T.Wang, Ch.majus L., D.Ieptopodum (Maxim.)Fedde)have three colpes,but the shape of colpus is different.
