Germinación de las Proteáceas Arbóreas Chilenas

Abstract

From 1981 to 1985 germination tests in laborator y and nursery with proveniences from th e Lake Región of the five tree chilean proteacea e wer e performed. Cold stratification in we t sand for different periods was used as pregermination treatment , depending on the species. Th e nursery tests were done in thre e substrates (sand. organic soil and norma l nursery soil) and seeds wer e sown during spring or Autumn.
High germination capacities were obtained for Gevuina avellana in spring and Autumn and at the three substrates. Nevertheless. an early sown withou t pretreatment , at norma l sustrate in Autumn , is recomended.
For Embothrium coccineum cold stratification in we t sand at 4° C during 60 to 90 days and sowing a t norma l substrat e during early days in september, is recommended.
Cold stratification in we t sand during 45 days, and sowing at norma l substrat e during early days in septembe r is recommende d for Lomatía hirsuta.
Best results for Lomatia ferruginea are obtained with cold stratification in wet sand at 4° C during 15 days, and sowing at normal substrate during september.
For Lomatia dentata, just sowing september at normal substrate, without pregermination treatment, is redomended.
