摘要
对芸苔族８种２变种的花粉进行了光镜和扫描电镜观察。其中４种２变种为首次报道。研究表明，芸苦族植物花粉形态特征基本一致，但在花粉大小、萌发孔类型以及外壁纹饰上种间存在一定的差异。同时发现该族植物的花粉大小与其染色体数有一定的相关性。
The pollen morphology of & species and 2 varieties of the Tribe Brassiceae from Chinaand other countries was examined under LM and SEM. 4 species and 2 varieties werepalynologically reported here for the first time. The results showed that the pollen morphology ofthe Brassiceae above-mentioned was consistent basically,but some difference between them inpollen size,aperture (Crambe abyssinica, 4-colpate) and exine sculpture was found. The presentpaper also found that the pollen size of these species might have certain correlationship with theirchromosome numbers.
