Antarctic Ocean and Resources Variability 1.5% acetocarmine and the slides are either analyzed the same day or stored at about 1°C in a refrigerator as described earlier (Jauhar 1981a). Pollen fertility is estimated by squashing mature anthers (before dehiscence) in a drop of 0.5% cotton blue in lactophenol.

Alina A. Fedotova,Sergey V. Kashinhe complete sterility of hybrids between them (Table 5.1, Fig. 5.1). Thus, so far as reproductive isolation is concerned, some ecotypes behave essentially as separate species (see Sect. 2.1). This is an enigmatic situation from the cytogenetic and breeding standpoints.
