Emergência de plântulas de Butia odorata (Barb. Rodr.) Noblick em casa de vegetação

Abstract: RESUMO -Butia odorata é uma palmeira nativa do Rio Grande do Sul, Brasil, cujos frutos são utilizados na alimentação humana. O objetivo deste estudo foi testar a emergência de plântulas de B. odorata em casa de vegetação a partir de sementes e diásporos submetidos a diferentes procedimentos de superação de dormência. A escarificação através da abertura da cavidade embrionária das sementes permitiu emergência de 72%, com tempo médio de 56 dias. A imersão dos diásporos em água por 18 h antes da semeadura favorec… Show more

“…The extraction of the seeds from the interior of the pyrenes and removal of the operculum seem to have greatly favored the absorption of water by the seeds. Fior et al [14] suggest that the opening of the embryo cavity by the removal of the operculum is the treatment that allows obtaining a higher percentage of seedlings of emerged palms, besides the shortest average time for emergence. The authors report the occurrence of a high percentage of germination in treatments composed of almonds without operculum (72.0%) and whole diaspores kept submerged in distilled water for 18 hours (67.2%) at the end of 440 days of evaluation.…”

“…1D), emission of leaf primordia, ELP (a structure emitted from ECP - Fig. 1F), germination velocity index (GVI), obtained by the evaluation of cotyledon petiole emission of the seeds every two days and using the formula [(GVI= n 1 /1 + n 2 /2 + … n i /t i ), where n i represents the number of seeds which had a protusion in the cotyledonary peciole in day t i ], proposed by Maguire [13], average germination time (AGT) according to Fior et al [14], percentage of seedlings contaminated by fungal colonies (CFC) and percentage of seeds contaminated by bacterial colonies (CBC).…”

“…Utilizou-se o delineamento experimental de blocos casualizados em esquema fatorial 2 x 6 com quatro repetições de 25 sementes. Os fatores avaliados foram frutos e sementes beneficiados, submetidos aos seguintes tratamentos: T1 = Frutos e sementes intactas; T2 = imersão em água por 12 horas; T3 = imersão em água por 24 horas; T4 = imersão em água por 48 horas; T5 = imersão em água por 72 horas (PINTO et al 2012); T6 = escarificação do poro germinativo para a retirada da película protetora do poro germinativo (FIOR et al, 2013). A determinação do grau de umidade foi realizada em quatro repetições de 10 sementes, adotando-se o método de estufa a 105 ± 3 °C, durante 24 horas (BRASIL, 1992).…”
