were classified according to Van der Pijl (1982) as anemochorous (winged or plumed diaspores
), zoochorous (scattered by animals), or autochorous (dispersed by explosion or gravity).
of parsnip (Pastinaca sativa) and radish (Raphanus sativus var.
For example, in wind dispersal, release height of the diaspore
is a key factor of the dispersal equation, with diaspores
released from tall plants traveling farther than those released from short plants (Howe & Smallwood, 1982; Willson & Traveset, 2000; Nathan & Katul, 2005; Thomson et al.
Additionally, larger islands have a higher probability to receive diaspores
than smaller ones and might provide a comparatively greater potential for in situ speciation because larger islands provide geographic features (such as mountain ranges or rivers) that are important for in situ speciation .
The X-ray test was efficient in evaluating the effects of desiccation on the diaspores
of Cryptocarya aschersoniana Mez.
were collected at the Estacao Ecologica de Caiua, state of Parana, Brazil (52[degrees] 49' - 52[degrees] 53' W and 22[degrees] 34' - 22[degrees] 37' S).
and produce high amounts of diaspores
, which may favour the re-infestation (Carvalho et al.
Overcoming dormancy in macaw palm diaspores
, a tropical species with potential for use as bio-fuel.
These mammals might consume or remove large number of diaspores
at every foraging bout (Jansen et al.
Glassman seeds presented 160 units, which number is lower than that observed by Brasil (2009), with 448 units, or in works by Leite (2001), with average of 497 diaspores
and lopes (2007) with Syagrus vagans (Bondar) A.
In this context, this study aimed to determine water desorption isotherms of pequi diaspores
, in order to obtain information on the amount of water that this product desorbs at the temperatures of 10, 20, 30 and 40 [degrees]C and water activities from 0.
They contain 1-5 diaspores
, which consist of one or two seeds united by the aril.
