Autecological studies on Audouinia capitata (Bruniaceae). I. Plant-derived smoke as a seed germination cue

Seeds of Audouinia capitata, a threatened fynbos species, are known to germinate under natural conditions only after fires. Experimental results are presented which demonstrate that seed germination is initiated by chemical factor(s) found in smoke, derived from burning fynbos plant material. Dit is bekend dat sade van Audouinia capitata, ’n bedreigde fynbos spesie, onder natuurlike toestande slegs na vure ontkiem. Eksperimentele resultate word aangebied waarin daar gedemonstreer word dat ontkieming van saad deur chemise faktor(e) aanwesig in rook afkomstig van brandende fynbos plantmateriaal, geïnisieer word.
