The relation of meiotic behaviour to hybridity, polyploidy and apomixis in the Ranunculus auricomus complex (Ranunculaceae)

Table 1 Analysis of male development in di- and polyploid Ranunculus gametes during sporogenesis. Mean percentages of normal and abnormal sporogenesis were determined by orcein staining and bright field microscopy
