| Abstract:
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. | |
