Seed dispersal is likely to have several benefits for different plant species. Seed survival is often higher away from the parent plant. This higher survival may result from the actions of density-dependent seed and seedling predators and pathogens, which often target the high concentrations of seeds beneath adults. [4]
Epilobium hirsutum — Seed head. In the broadest sense, dispersal occurs when the fitness benefits of moving outweigh the costs. There are a number of benefits to dispersal such as locating new resources, escaping unfavorable conditions, avoiding competing with siblings, and avoiding breeding with closely related individuals which could lead to inbreeding depression.
Afzelia africana seeds bearing elaiosomes Chelidonium majus diaspores consisting of hard-coated seeds and attached elaiosomes. Myrmecochory (/ m ɜːr m ɪ ˈ k ɒ k ɔː r i / (sometimes myrmechory); [1] from Ancient Greek: μύρμηξ, romanized: mýrmēks ("ant") and χορεία khoreíā ("circular dance") is seed dispersal by ants, an ecologically significant ant–plant interaction ...
This type of seed dispersal is termed myrmecochory from the Greek "ant" (myrmex) and "circular dance" (khoreíā). This type of symbiotic relationship appears to be mutualistic , more specifically dispersive mutualism according to Ricklefs, R.E. (2001), as the plant benefits because its seeds are dispersed to favorable germination sites, and ...
Zoochory is the dispersal of the seeds of plants by animals. This is similar to pollination in that the plant produces food resources (for example, fleshy fruit, overabundance of seeds) for animals that disperse the seeds (service). Plants may advertise these resources using colour [17] and a
A different class of shattering mechanisms involves dehiscence of the mature fruit, which releases the seeds. Rapeseed and the shattering types of sesame are harvested before the seed is fully mature, so that the pods do not split and drop the seeds. [3] [4] [5] Harvesting shattering types of sesame involves wrapping the cut plants before ...
