Title A name given to the resource Estrutura populacional e desenvolvimento da fase esporofítica de Cyathea delgadii Sternb. (Cyatheaceae, Monilophyta) no sul do Brasil Population structure and development of the sporophyte phase of Cyathea delgadii Sternb. (Cyatheaceae, Monilophyta) in Southern Brazil Creator An entity primarily responsible for making the resource Jairo Lizandro Schmitt, Paulo Günter Windisch Description An account of the resource Cyathea delgadii Sternb. é uma samambaia arborescente que ocorre em florestas primárias e secundárias da região nordeste até o sul do Brasil. O presente estudo discute a estrutura populacional e o desenvolvimento da fase esporofítica (crescimento do cáudice, produção de frondes, fenologia da produção de esporos) de C. delgadii, em floresta secundária, no Estado do Rio Grande do Sul, Brasil, baseado na observação de 41 plantas, durante 13 meses. A espécie apresentou padrão espacial agregado e uma freqüência expressivamente alta de indivíduos de menor altura, indicando um grande potencial de regeneração da população. O cáudice das plantas cresceu, em média, 4,65 cm ano-1, sendo que as maiores taxas de crescimento foram registradas em plantas mais altas. As taxas de produção de frondes novas (5,75 frondes ano-1) e de senescência (4,92 frondes ano-1) similares evidenciaram uma capacidade de manter um número de frondes estável. Poucas plantas formaram frondes férteis, sendo que a produção e liberação dos esporos ocorreram assincronicamente.Cyathea delgadii Sternb. is a tree fern that grows in primary and secondary forests from Norhteastern to Southern Brazil. This study discusses the population structure and development of the sporophytic phase (caudex growth, frond production, phenology of spore production) of C. delgadii in a secondary forest in the State of Rio Grande do Sul, Brazil, based on observations of 41 plants during a 13 month period. The species had an aggregated spatial distribution pattern and higher frequency of smaller individuals, indicating high potential for population regeneration. On average, the caudex of plants grew 4.65 cm year-1, and the highest growth rates were recorded for taller plants. The similar frond production rate (5.75 fronds year-1) and senescence rate (4.92 fronds year¹) reflect the capacity to maintain a stable number of fronds. Only a few plants formed fertile fronds, while spore production and liberation occur in an asynchronous pattern.
