| 摘 要： | 本文通过对甘蓝和芥蓝的核型分析和花粉形态的扫描电镜观察，认为它们的核型并不完全一致，而花粉形态的明显区别说明芥蓝是一个独立的种，与芸苔属其他种不很亲缘。

| Abstract: | The karyotypes and pollen morphology of Brassica oleracea L. and B. alboglabra
Bailey were studied by preparing mitotic chromosome specimens and scanning electron micro-
scope. The results are as follows: 1. the karyotypes of the 4 varieties in B. oleracea L. and of
B. alboglabra Bailey are similar, all with the same chromosome number (2n=18) satellite
number (one pair) and a type of karyotype, but different in respect to satellite position and
karyotype symmetry 2. The pollengrains of 2 varieties of B. oleracea L. are 3-colporate and
reticulate, distinctly different from those in B. alboglabra, which are pantoporate with smaller
lumina.
Based on the results we tend to regard that B. alboglabra Bailey is an independent species. |
