SIMABUKURO, ELIANA A.; CARVALHO, MARIA ANGELA M. DE and FELIPPE, G. M.. Reserve substances and storage of Cyathea delgadii Sternb. spores. Rev. bras. Bot. [online]. 1998, vol.21, n.2, pp.149-152. ISSN 1806-9959. http://dx.doi.org/10.1590/S0100-84041998000200006.
The spores used were collected from a population of trees of Cyathea delgadii Sternb. growing in a gallery forest at the Reserva Biológica e Estação Experimental de Moji Guaçu, São Paulo state, Brazil (22°18S and 47°11W). The germination of spores of Cyathea delgadii decreases with time when kept in closed bottles under storage at 4°C in darkness. Germination is still very high after storage for one year. Spores stored for three years do not germinate. The results also show a decrease in soluble proteins and an increase in starch after several months storage.
