In home gardens, for example, the seeds of plants which are otherwise difficult to grow from seed may be made viable through scarification. The thawing and freezing of water, fire and smoke and chemical reactions in nature are what allow seeds to germinate but the process can be sped up by using the various methods described thus far.
The staggering of germination safeguards some seeds and seedlings from suffering damage or death from short periods of bad weather or from transient herbivores; it also allows some seeds to germinate when competition from other plants for light and water might be less intense. Another form of delayed seed germination is seed quiescence, which ...
Longleaf pine (Pinus palustris) is a pyrophile, depending on fire to clear the ground for seed germination. [4] The passage of fire, by increasing temperature and releasing smoke, is necessary to raise seeds dormancy of pyrophile plants such as Cistus and Byblis an Australian passive carnivorous plant. Imperata cylindrica is a plant of Papua ...
Allium ochotense, or the Siberian onion, [3] is a primarily East Asian species of wild onion native to northern Japan, Korea, China, and the Russian Far East, as well as on Attu Island in Alaska.
Chives are cultivated both for their culinary uses and for their ornamental value; the violet flowers are often used in ornamental dry bouquets. [29] Chives thrive in well-drained soil, rich in organic matter, with a pH of 6–7 and full sun. [30] They can be grown from seed and mature in summer, or early the following spring.
Dormant seeds are viable seeds that do not germinate because they require specific internal or environmental stimuli to resume growth. Under proper conditions, the seed begins to germinate and the embryo resumes growth, developing into a seedling. [clarification needed] Step 1: Water imbibition, the uptake of water, results in rupture of seed coat.
Seeds of many trees, shrubs and perennials require these conditions before germination will ensue. [citation needed] In the wild, seed dormancy is usually overcome by the seed spending time in the ground through a winter period and having its hard seed coat softened by frost and weathering action. By doing so the seed is undergoing a natural ...
Allium flavum (yellow) and Allium carinatum (purple). Allium is a large genus of monocotyledonous flowering plants with around 1000 accepted species, [4] [5] making Allium the largest genus in the family Amaryllidaceae and amongst the largest plant genera in the world. [6]
