On the theory of explosively dispersed seeds

WebThe scattering of seeds or fruits is known as dispersal. There are two reasons for seeds to be dispersed: To prevent overcrowding. Dispersal ensures that the young plants grow far apart from each other. This reduces competition between the young plants and/or with the parent plant for sunlight, water, nutrients and space. Web5 de jul. de 2011 · We provided the first large-scale, cross-species quantification of the correlations between dispersal distance and both seed mass and plant height. Seed …

WebSeeds are sometimes partly imbedded in firm ground. Some seeds are buried in soft soil at a considerable angle to the vertical. The dispersal distance of an explosively dispersed seed is defined as the horizontal distance between this seed and the nearest edge of the crown.
