Abstract:
Pollen viability was tested at various times during anther opening in three anemophilous (Chamaerops humilis, Festuca arundinacea, Mercurialis annua) and three entomophilous (Acanthus mollis, Cucurbita pepo, Spartium junceum) species. In certain species of both pollination types (Cucurbita pepo, Festuca arundinacca, Mercurialis annua), all pollen grains were dead 72 h after anthesis, and in others (Spartium junceum, Acanthus mollis, Chamaerops humilis) viability lasted longer. The results are discussed in terms of the reproductive ecophysiology of the species.
