Seed bank dynamics of an invasive plant, Ambrosia artemisiifolia L.
2008
AbstractThe seed-bank dynamics ofAmbrosia artemisiifolia(Asteraceae), an annual invasive plant introduced from North America to Europe, were studied in nine French populations developing in field crops, set-asides or wastelands. The vertical distribution of seeds was studied in two different depth sections (0–5 cm and 5–20 cm), and the spatial horizontal pattern of distribution was analysed for two selected field-crop and set-aside populations. The proportions of dormant, non-dormant and dead seeds, as well as the changes in seed-bank dormancy over time, were evaluated. Natural seedling recruitment and its variation under different disturbance treatments in competitive set-asides were also …
Increasing tree survival to facilitate the conversion of conventional systems to agroforestry systems using plant growing aids and plant-plant facili…
2022
Several global commitments have established a compromise to greatly increase the presence of trees in agricultural lands, fostering therefore the adoption of agroforestry systems and the destination of some areas for reforestation. Such tasks are challenging, particularly under the current climate change scenarios, and several studies have demonstrated a high risk of seedling mortality under harsh and extremely variable environmental conditions, calling for solutions that must increase the success and reduce the costs of growing a tree. In this study, inside the project LIFE Desert Adapt, we tested the effects of different types of growing aids such as shelters, mulching and innovative meth…
