    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 ...

  3. Germination - Wikipedia

    en.wikipedia.org/wiki/Germination

    It is a measure of germination time course and is usually expressed as a percentage, e.g., an 85% germination rate indicates that about 85 out of 100 seeds will probably germinate under proper conditions over the germination period given. Seed germination rate is determined by the seed genetic composition, morphological features and ...

  4. Seedling - Wikipedia

    en.wikipedia.org/wiki/Seedling

    In most seeds, for example the sunflower, the plumule is a small conical structure without any leaf structure. Growth of the plumule does not occur until the cotyledons have grown above ground. This is epigeal germination. However, in seeds such as the broad bean, a leaf structure is visible on the plumule in the seed. These seeds develop by ...

  5. Agricultural cycle - Wikipedia

    en.wikipedia.org/wiki/Agricultural_cycle

    Germination is a process by which the seed develops into a seedling. The vital conditions necessary for this process are water, air, temperature, energy, viability and enzymes. If any of these conditions are absent, the process cannot undergo successfully.

  6. 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.

  7. 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 ...

  8. Scarification (botany) - Wikipedia

    en.wikipedia.org/wiki/Scarification_(botany)

    Using thermal and chemical scarification, germination increased to 48.8% and 44% respectively. 68% of Longspur lupine seeds germinated in the control group, while all scarification methods decreased the success rate of germination. The silvery lupine had 52% of its control group germinate but through mechanical scarification it rose to 85.2%.

  9. 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 ...
