  2. Seed Starting on a Budget Series: Germination - AOL

    www.aol.com/seed-starting-budget-series...

    Knowing how long a seed should take to germinate is an integral part of the seed starting process. If quick-to-sprout seeds like mizuna and lettuce are taking longer than seven days, you can be ...

    Furthermore, releasing a large number of seeds at once, rather than gradually, increases the possibility that some of those seeds will escape predation. [16] Similar pressures apply in Northern Hemisphere conifer forests, but in this case there is the further issue of allelopathic leaf litter, which suppresses seed germination. Fire clears out ...

    In 2003, the website released the Virtual Pocket Seed Experiment, the first of several data sets that could be used in and outside of the classroom. The experiment was based on the classic seed germination experiment, but included the feature of time-lapse animation of various seed experiments.

  5. Sowing - Wikipedia

    In addition to the mentioned seed pretreatments, seed germination is also assisted when a disease-free soil is used. Especially when trying to germinate difficult seed (e.g. certain tropical fruit), prior treatment of the soil (along with the usage of the most suitable soil; e.g. potting soil, prepared soil or other substrates) is vital.

  6. Epigenetics of plant growth and development - Wikipedia

    en.wikipedia.org/wiki/Epigenetics_of_Plant...

    Germination is the early growth of a plant from a seed. Meanwhile, dormancy precedes germination and serves to preserve a seed until conditions are receptive towards growth. The transition from dormancy to germination seems to depend on the removal of factors inhibiting growth. There are many models for germination which may differ between species.

  7. Gibberellin - Wikipedia

    en.wikipedia.org/wiki/Gibberellin

    Gibberellins cause also seed germination by breaking the seed's dormancy and acting as a chemical messenger. Its hormone binds to a receptor, and calcium activates the protein calmodulin , and the complex binds to DNA, producing an enzyme to stimulate growth in the embryo.

  8. Plant reproduction - Wikipedia

    en.wikipedia.org/wiki/Plant_reproduction

    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.

  9. 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%.
