This study determined germination responses of 19 species, including trees, shrubs, vines, and herbs, under natural gap and non-gap conditions, in a secondary forest in Chiloé Island, southern Chile, in order to assess if there is any association between the habitat where the seedlings of these plant species occur and their germination requirements. Statistical differences in percentage seed germination were detected in six species in a gap habitat compared to the understory. Five forest edge species (Embothrium coccineum, Escallonia rubra, Gunnera tinctoria, Nertera granadensis and Rhaphithamnus spinosus) presented greater germination success in the canopy gap, while only one forest interior species (Myrceugenia planipes) germinated to a lesser extent in... |

The Juan Fernández Islands contain one of the world's most interesting floras. However, their conservation status is fragile due to direct and indirect human activities. With the aim of contributing to the conservation of the native species of these islands, germination trials have been performed under laboratory conditions. We studied the germination patterns and characteristics of 25 taxa of the archipelago, at temperatures between 15°C and 25°C, with 12.5 h. of photoperiod. Thirty-five percent of the studied species germinated immediately (within the first month after sowing), while 50% had a delayed germination. Three species did not germinate. Regarding the germination pattern, nine taxa (53%) germinated synchronously (³ 90% of seeds germinated within... |

En Chile central existe una rica flora vascular nativa y una alta proporción de plantas exóticas. Con el objeto de incrementar nuestro conocimiento sobre la composición de la fora exótica, naturalizada en Chile central, se describe y analiza aquella presente en la vertiente occidental de la cordillera de la Costa de la Provincia de Valparaíso en sitios con diferentes tipos de uso. Específcamente, se establecen la riqueza taxonómica, la forma de vida, el origen geográfco y de las especies exóticas en diversas áreas de la provincia. Se identifcaron 323 especies, de las que un 34% fueron exóticas; de ellas, un 74% fue de origen europeo y el 10% euro-norteafricano. En los sitios muestreados, las nativas sólo alcanzaron a un 23 % de la cobertura absoluta, en... |
