There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals. Some plants are serotinous and only disperse their seeds in response to an environmental stimulus. These modes are typically inferred based on adaptations, such as wings or fleshy fruit. [1]
Seed dispersal is the movement or spread of seeds away from the parent plant. Seed dispersal increases the odds that at least some seeds will find a suitable site for germination and growth, and it can help reduce competition between parent and offspring for resources and sunlight.
30 gru 2021 · Seed dispersal is the adaptive mechanism in seed-bearing plants, involving the movement or transport of seeds away from the parent plant to ensure their germination. It is commonly known as the ‘scattering of seed.’
Wind dispersal is a remarkable adaptation that allows plants to conquer new territories, ensure genetic diversity, and shape ecosystems. Through their ingenious structures and mechanisms, wind-dispersed seeds harness the power of air currents to travel far and wide.
17 maj 2014 · Long-distance dispersal (LDD) of plant seeds by wind is affected by functional traits of the species, specifically seed terminal velocity and height of seed release above the vegetation cover (HAC), as well as by the meteorological parameters wind speed and vertical turbulence.
7 sie 2015 · This scattering, also called dispersal, helps distribute seeds which helps plants reproduce. Wind can carry seeds away from their plants, but how far a seed travels has a lot to do with characteristics of the seed itself. What makes some seeds travel farther than others?
25 lip 2002 · Here we show that mechanistic models coupling seed release and aerodynamics with turbulent transport processes provide accurate probabilistic descriptions of LDD of seeds by wind.
