| Germination of spores of Cyathea delgadii was carried out in soils collected in March 1997 (rainy season) at three depths (0-5, 5-10 and 10-15 cm) from the cerrado, open-cerrado, gallery forest and marsh at Moji Guaçu and cerradão, cerrado and gallery forest at Pedregulho, in Itirapina, both in the state of São Paulo, Brazil. Viability of spores mixed with soil and buried in the cerrado at the Reserva in Moji Guaçu were conducted for up to 10 months. The spores germinated in all soils. Germination in the soils was significantly lower than in distilled water. Germination was higher in soils from the gallery forest and cerrado than from open cerrado, cerradão and marsh. The germination was the same in the soil samples from the three depths of gallery forest,... |
