ROOTING RESPONSES OF SOME CHILEAN PROTEACEAE WITH ORNAMENTAL POTENTIAL

Six species, distributed in four genera of Proteaceae are native to Chile.
Among them, Embothrium coccineum, is grown as an outstanding ornamental tree, whereas Gevuina avellana is used as a nut species, as well as a source of cut greens, similar to Lomatia ferruginea. The three species are distributed in south-central Chile and Argentina.
Cutting propagation was assessed by using differential IBA concentrations ranging from 0 to 5000 ppm for E. coccineum or 0 to 4000 ppm for G. avellana and L. ferruginea, in different substrates, under high humidity conditions.
Best rooting (62%) for E. coccineum were obtained with low IBA concentrations (300-600 ppm). Up to 78% rooting was achieved in G. avellana with cuttings taken in summer and 4000 ppm IBA, while 67% and up to 10 roots per cutting were observed in L. ferruginea without hormonal treatments.
Different growing conditions are discussed for these species.
