2. Germination - Wikipedia

   en.wikipedia.org/wiki/Germination

   When ABA levels are higher than GA then that leads to dormant seeds and when GA levels are higher, seeds germinate. [25] The switch between seed dormancy and germination needs to occur at a time when the seed has the best chances of surviving and an important cue that begins the process of seed germination and overall plant growth is light.

   Image Credit: 123RF. Not all seeds sprout at the same rate. While environmental conditions may alter germination time (e.g., if the soil is too cold, tomato seeds may take longer to germinate ...

4. Seed - Wikipedia

   en.wikipedia.org/wiki/Seed

   The germination percentage is simply the proportion of seeds that germinate from all seeds subject to the right conditions for growth. The germination rate is the length of time it takes for the seeds to germinate. Germination percentages and rates are affected by seed viability, dormancy and environmental effects that impact on the seed and ...

5. Seed dormancy - Wikipedia

   en.wikipedia.org/wiki/Seed_dormancy

   An important function of seed dormancy is delayed germination, which allows dispersal and prevents simultaneous germination of all seeds. 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 ...

6. Stratification (seeds) - Wikipedia

   en.wikipedia.org/wiki/Stratification_(seeds)

   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 ...

7. Plant propagation - Wikipedia

   en.wikipedia.org/wiki/Plant_propagation

   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.
