Crecimiento anual de cuatro especies arbóreas con yemas desnudas nativas de los bosques templados húmedos de Patagonia. Sosa, Claudia M. Puntieri, Javier G. Arquitectura Aextoxicon punctatum crecimiento primario Luma apiculata Myrceugenia exsucca selva valdiviana Sophora microphylla. Annual growth of four naked-bud tree species from the temperate rainforests of Patagonia.Plant species inhabiting regions with low seasonality in climate tend to exhibit some morpho-architectural features that occur less frequently in species from regions with seasonal climate. This study was aimedat evaluating the primary growth of nursery-grown trees of four woody species native to the temperate rainforests of Patagonia, also known as Valdivian rainforests, where the degree of seasonality is lower than in other Patagonian forests. The selected species, Aextoxicon punctatum, Luma apiculata, Myrceugenia exsucca and Sophora microphylla, have naked buds, like many tropical species. Fenology, growth and branching of the main axis of marked plants were evaluated during one calendar year. Primary growth was markedly seasonal in all four species, as previously recorded for coexisting tree species with scaly buds. However, notable intra- and inter-specific differences in the onset and completion of growthwere detected; L. apiculata and M. exsucca (Myrtaceae) exhibited higher intra-specific variations than the other two species. Our results indicate that several factors would be involved in regulating primary growth in these species, something found in species with continuous growth. Las especies vegetales que habitan en regiones con bajo nivel de estacionalidad en el clima suelen presentar rasgos morfo-arquitecturales que ocurren con menor frecuencia en especiesde regiones con clima estacional. El objetivo de este estudio fue evaluar el crecimiento primario en vivero de cuatro especies leñosas típicas de los bosques templados húmedos de Patagonia, conocidoscomo selva valdiviana, donde el grado de estacionalidad es menos marcado que en otros bosques patagónicos. Las especies estudiadas, Aextoxicon punctatum, Luma apiculata, Myrceugenia exsucca ySophora microphylla, comparten con muchas especies tropicales la posesión de yemas desnudas. Se evaluaron, durante un año calendario, la fenología, el crecimiento y la ramificación del eje principal de plantas marcadas. El crecimiento primario en estas especies fue marcadamente estacional, como en se ha registrado en especies arbóreas con yemas escamosas con las que coexisten. Sin embargo, se detectaron notables diferencias intra- e inter-específicas en el inicio y la finalización del crecimiento; L. apiculata y M. exsucca (Myrtaceae) presentaron mayores variaciones que las restantes dos especies.Nuestros resultados indican la intervención de varios factores reguladores del crecimiento primario en las especies estudiadas, como ocurre en especies con crecimiento continuo.
