ANACLETO, Adilson; NEGRELLE, Raquel Rejane Bonato  e  KOEHLER, Henrique Soares. Germination of Aechmea nudicaulis (L.) Griseb. (Bromeliaceae) in different substracts as alternatives to Dicksonia sellowiana Hook. Acta Sci., Agron. [online]. 2008, vol.30, n.1, pp.73-79. ISSN 1807-8621.  http://dx.doi.org/10.4025/actasciagron.v30i1.1134.

For this study, the germination of Aechmea nudicaulis (L.) Griseb. (Bromeliaceae) was evaluated. Production attempts from seeds for this species have taken place in an empirical form, using substrate based on xaxim (Dicksonia sellowiana Hook.) powder, the use of which is currently restricted, as it is an endangered species. Five easily accessible alternative substratum were tested: worm humus, sand, coconut shell fiber, forest litter, and Plantmax®. The experiment was conducted using a completely randomized design, with four replications and 50 seeds per experimental unit, at room temperature in a rustic nursery covered with 70% shade cloth. Weekly readings were performed during 70 days. The best alternative as a substitute to xaxim was forest litter, due to its germinability of 79.5% and survival rates of 97%, significantly similar to xaxim (78%; 94.75%; Tukey p < 0,05). Additionally, this product features positive characteristics such as high availability, low cost, and easy recycling.
