Epilobium hirsutum seed head dispersing seeds. In spermatophyte plants, seed dispersal is the movement, spread or transport of seeds away from the parent plant. [1] Plants have limited mobility and rely upon a variety of dispersal vectors to transport their seeds, including both abiotic vectors, such as the wind, and living vectors such as birds.
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 ...
Euphorbia is a large and diverse genus of flowering plants, commonly called spurge, in the family Euphorbiaceae. Euphorbias range from tiny annual plants to large and long-lived trees, [ 2 ] with perhaps the tallest being Euphorbia ampliphylla at 30 m (98 ft) or more.
In botany, a diaspore is a plant dispersal unit consisting of a seed or spore plus any additional tissues that assist dispersal. In some flowering plants, the diaspore is a seed and fruit together, or a seed and elaiosome. In a few plants, the diaspore is most or all of the plant, and is known as a tumbleweed.
There are two types of African milk tree plants: Euphorbia trigona, the green one, and Euphorbia trigona ‘Rubra’, a predominantly red one. They require the same care, although Rubra can handle ...
It is uncommon for pathogens to be transmitted from the plant to its seeds (in sexual reproduction or in apomixis), though there are occasions when it occurs. [2] [page needed] Seeds generated by apomixis are a means of asexual reproduction, involving the formation and dispersal of seeds that do not originate from the fertilization of the embryos.
Euphorbia hirta (sometimes called asthma-plant [3]) is a pantropical weed, originating from the tropical regions of the Americas. [4] It is a hairy herb that grows in open grasslands , roadsides and pathways.
