30 gru 2021 · 1) Wind: Seeds of plants such as maple, milkweed, dandelion, swan plants, and cottonweed trees are light and feathery, which helps them carry to a distant place by the wind. In contrast, some plants like maple have winged seeds that do not float but flutter to the ground.
Incredibly, a number of plant species utilize explosive force to fling their seeds away. Many mistletoes have explosive fruits with sticky seeds to (hopefully) propel their parasitic offspring high into neighboring trees.
Seed Ejection: Certain plants have structures that actively eject seeds, increasing the chances of wind dispersal. Seed Dislodgement: Other plants have seeds that are easily dislodged from their parent plant by wind or physical disturbances.
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.
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.
16 lut 2011 · Dispersal occurs when seeds move away from the source plant. The length of this movement, the dispersal distance D, is the measure of the dispersal process, and the distribution of dispersal distances, the seed dispersal kernel p (x), is its basic statistical descriptor.
6 sie 2015 · Seed dispersal allows plants to spread out from a wide area and avoid competing with one another for the same resources. Other seeds are dispersed by the wind—such as the "winged" seeds from a...
