Fig. 1From: Comparison of six different methods to calculate cell densitiesa Three day-old eggplant microspore culture. Cultures at this stage are principally composed of regular eggplant microspores together with few slightly enlarged microspores (arrows). b Eighteen day-old eggplant microspore culture. Cultures at this stage are principally composed of regular eggplant microspores together with few enlarged microspores or microspore-derived embryos (arrows). c Fluorospheres. These particles are very regular in size and shape. Bars: 50 µmBack to article page
