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.

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.
Seed enhancement is a range of treatments of seeds that improves their performance after harvesting and conditioned, but before they are sown. They include priming, steeping, hardening, pregermination, pelleting, encrusting, film-coating, tagging and others, but excludes treatments for control of seed born pathogens .
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 ...
In 1879 Beal started one of the longest-running experiments in botany. He filled 20 bottles with a mixture of sand and seeds, with each bottle containing 50 seeds from 21 species of plant. Then the bottles were buried, their necks pointing down to exclude water.
[1] The photomorphogenesis of plants is often studied by using tightly frequency -controlled light sources to grow the plants. There are at least three stages of plant development where photomorphogenesis occurs: seed germination, seedling development, and the switch from the vegetative to the flowering stage ( photoperiodism ).
He was a professor of chemistry at Penn State University and is known as one of the foremost researchers in seed germination theory. He researched the biochemical reactions that underlie the germination of all seeds, performing germination research on plant species from 150 families, 800 genera, and 2500 species over the course of his career.
