Abstract
In anther cultures of Anemone canadensis L., Anemone dichotoma L., Anemone hupehensis Lemoine, Clematis viticella L. and Papaver setigerum DC. a positive relationship between incubation in 2% CO 2 and the production of microspore‐derived embryos was observed. In anther cultures of Nicotiana tabacum L., Anemone hupehensis and Clematis viticella a combination of cold treatment (7°C) and incubation in 2% CO 2 increased embryo production. In Anemone canadensis cold treatment increased the number of proembryos, whereas incubation in 2% CO 2 had no effect. In Anemone hupehensis 5% CO 2 increased embryo production by more than 2%. In Anemone dichotoma and Papaver setigerum 2% CO 2 was the more efficient level. CO 2 had no significant effect on pH in the culture medium in anther cultures of Anemone canadensis.
