Selffertilization in Campanula rotundifolia L. s. 1. group
Artificial selfpollination of six taxa of C. rotundifolia L. group was perfomed. More than 60% of the tetraploid plants and diploid C. rotundifolia s. str. representatives set seeds which germinated in some 42-76%. The seed setting in C. serrata was a little lower and the germination was very poor (...

Artificial selfpollination of six taxa of C. rotundifolia L. group was perfomed. More than 60% of the tetraploid plants and diploid C. rotundifolia s. str. representatives set seeds which germinated in some 42-76%. The seed setting in C. serrata was a little lower and the germination was very poor (0.07%). Only 18% of C. cochleariifolia plants yielded seeds after selfpollination. These seeds failed to germinate. The selfed offspring was viable only in part. Some developmental distur-bances were observed.
