A plant DNA ligase that is involved in repair of single- and double-strand breaks during seed germination is an important determinant of seed longevity. [52] Also, in Arabidopsis seeds, the activities of the DNA repair enzymes Poly ADP ribose polymerases (PARP) are likely needed for successful germination. [ 53 ]
A seed plant or spermatophyte (lit. ' seed plant '; from Ancient Greek σπέρματος (spérmatos) 'seed' and φυτόν (phytón) 'plant'), also known as a phanerogam (taxon Phanerogamae) or a phaenogam (taxon Phaenogamae), is any plant that produces seeds.
Seeds and spores can be used for reproduction (e.g. sowing). Seeds are typically produced from sexual reproduction within a species because genetic recombination has occurred. A plant grown from seeds may have different characteristics from its parents. Some species produce seeds that require special conditions to germinate, such as cold treatment.
To be successful at seed saving, new skills need to be developed to ensure that desired characteristics are retained in the landraces of the plant variety. Important considerations are the separation distance needed from plants of the same species to ensure that cross-pollination with another variety does not occur, and the minimum number of plants to be grown which will preserve inherent ...
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.
