Seed and Germination Characteristics of 20 Amazonian Liana Species.
Lianas are an important component of tropical forests, and may reach their highest densities in disturbed areas. However, information on seed and germination characteristics is scarce. Twenty Amazon liana species were screened for their germination characteristics, including light dependence, tolerance of desiccation and of alternating temperatures; these characteristics are considered importan...
متن کاملEcological significance of seed germination characteristics in flood-meadow species
In climate chamber and outdoor experiments we analysed germination traits of 42 vascular plant species typical of floodmeadows of the alliance Cnidion. In Central Europe such flood-meadows and their highly endangered character species are confined to large lowland river corridors with a dry and warm climate. Due to the prevailing ecological conditions, particularly the extremely high variabilit...
متن کاملRapid and High Seed Germination and Large Soil Seed Bank of Senecio aquaticus in Managed Grassland
Senecio aquaticus, regionally a Red List species in Europe, has become increasingly abundant in agricultural grassland of medium to high management intensity in Switzerland, Southern Germany, and Austria in recent years, where it is a threat for animal and human health due to its toxicity. In this study, we investigated the seed ecology of S. aquaticus to help protection of the species in relic...
متن کاملFire effects on composition, density and species diversity vegetation and soil seed bank (Case study: Kangavar rangelands)
Abstract Background and objectives: Fire as a frequent phenomenon in rangelands and because of its complicated and different effects on natural ecosystems, has great importance. Awareness of such fire effects on vegetation cover in point of rangeland management after fire is important and helps better Understanding and sustainable management of rangelands. Changing in plant structure and compo...
متن کاملSeed germination and vigor.
Germination vigor is driven by the ability of the plant embryo, embedded within the seed, to resume its metabolic activity in a coordinated and sequential manner. Studies using "-omics" approaches support the finding that a main contributor of seed germination success is the quality of the messenger RNAs stored during embryo maturation on the mother plant. In addition, proteostasis and DNA inte...
