were stored in paper bags at room temperature until they were needed in January 2011.
Although dispersal is probably mainly by gravity, the diaspores
can also float for several days before becoming waterlogged and sinking (Conran pers.
Soon after, each filter-paper disk received 50 diaspores
from the target-species (lettuce/onion), randomly arranged, with four replications for each treatment, according to Brasil (1992).
Interactions between ants and the diaspores
of some common spring-flowering herbs in West Virginia.
Dans cet article, l'auteure examine deux recits diaspores

Wild poinsettia diaspores
were scarified in pure sulfuric acid for five seconds and then washed in running water to standardize the seed integuments (AZANIA et al.
Morphological patterns of diaspores
from animal-dispersed tree and treelet species at Parque Estadual de Itapua, Rio Grande do Sul State, Brazil.
The effects of morphology, orientation and position of grass diaspores
on seedling survival.
These authors have reported that the imbibition of the diaspores
in water (28[degrees]C) for 48 hours or the removal of the endocarp did not increase the germination percentage (41 and 37%, respectively), and the results were not different from the control diaspores
, which reached 46% germination.
Mass allocation, moisture content, and dispersal capacity of wind-dispersed tropical diaspores
In this context, this study aimed to evaluate the allelopathic potential of aqueous extracts of young and mature leaves of Sapindus saponaria on the germination of diaspores
and growth of seedlings of Echinochloa crus-galli (L.
The feasibility of intercontinental sedge dispersal by migrating waterfowl was shown by de Vlaming and Proctor (1968) who demonstrated viability of Carex and other sedge diaspores
after more than 24h in the digestive systems of mallard ducks and suggested that these highly resistant seeds were an adaptive trait in wetland sedges.
