“…Then distilled water was added to the soil and the Petri dish was sealed with parafilm. The dishes were kept in growth cabinets at constant 25 °C and continuous white light at 437 mW.cm -2 .s -1 at Petri dish level (Ruggiero & Zaidan, 1997). The number of two-dimensional gametophytes was counted two and four months from the beginning of the germination experiment using a stereomicroscope.…”

“…Considerando a quantidade de sementes produzidas, a abundância de indivíduos dessa família na RBEE de Mogi Guaçu e a relativa facilidade com que germinam, é de interesse conhecer as condições de luz e temperatura que favorecem a germinação, de modo a fornecer dados básicos sobre esse processo em sementes de algumas Melastomataceae do Cerrado. (Ruggiero & Zaidan 1997). Para cada experimento de germinação foram feitas quatro repetições, cada uma com 50 sementes, em placas de Petri, forradas com duas folhas de papel de filtro e saturadas com água destilada.…”

“…Várias sementes de espécies de cerrado germinam nessa faixa de temperatura (Felippe & Silva 1984;Felippe 1986;Ruggiero & Zaidan 1997;Cesarino & Zaidan 1998). A 20 e 25°C no escuro, porém, a germinação não chega a 3% até o décimo dia.…”

“…bras. 12(3): 349-356.1998 (Suplemento) (Ruggiero & Zaidan 1997). Cada tratamento fotoperiódico consistiu de cinco vasos (ldm 3 de capacidade) com duas plantas cada um, em terra de mata do Instituto de Botânica de São Paulo e o mesmo número de plantas para a terra de cerrado de Moji Guaçu, totalizando 10 plantas em cada tipo de solo.…”
