The effects of fire-related cues on seed germination and viability of Helenium aromaticum (Hook.) H.L. Bailey (Asteraceae)
Provedor de dados: Gayana Botánica
Autores: Gómez-González,Susana; Torres-Díaz,Cristian; Gianoli,Ernesto.
Se evaluó el efecto de la temperatura y el humo sobre la germinación de Helenium aromaticum; una planta anual abundante en matorrales incendiados. Encontramos que las semillas son resistentes a la alta temperatura (100°C) y al humo, pero su germinación no es estimulada por estos factores. Otras señales del fuego deben ser evaluadas.

COMPETITIVE EFFECTS OF THE ALIEN INVASIVE CENTAUREA SOLSTITIALISL. ON TWO CHILEAN BACCHARIS SPECIES AT DIFFERENT LIFE-CYCLE STAGES
Provedor de dados: Gayana Botánica

Several studies have revealed a variety of mechanisms of invasion of alien plant species. However, little is known on how those mechanisms and their associated effects on native species change across different life-cycle stages. Under controlled conditions, we assessed the interactions between the alien invasive species Centaurea solstitialis L. (Asteraceae) and two pioneer native species to the Chilean matorral; Baccharis linearis (Ruiz et Pav.) Pers. and B. paniculata DC. (Asteraceae). Competitive effects of the invader on natives were evaluated by combining different life-cycle stages: seed-seed, plant-seed, and plant-plant. Seed germination of C. solstitialis was explosive and much faster than that of the native species. The presence of C. solstitialis...
