Effects of sucrose and irradiance on germination and early gametophyte growth of the endangered tree fern Dicksonia sellowiana Hook (Dicksoniaceae) Efeito da sacarose e irradiância na germinação e crescimento inicial do gametófito da samambaia arbórea Dicksonia sellowiana Hook (Dicksoniaceae) em perigo de extinção

It is an endangered tree fern that grows in mixed umbrophylus forests in the tropics. Sterilized spores were germinated at 25 ± 2ºC under a 16-hour photoperiod, in Dyer and MS medium supplemented with 0 to 5% sucrose. The germination was lower with the addition of sucrose. Dry mass was higher in 30-...
