Germination |
Most people are used to planting crop or horticultural seed. These have been bred to have high germination rates and to germinate quickly. Seed of native or wild plants are often not like this; if they were they would germinate at the wrong time and would not survive as seedlings. They have some kind of dormancy that must be broken by environmental cues that tell the seed that, based on prior evolutionary history and recent conditions, it should now be safe to germinate. There are also treatments, unlikely to be seen by a seed in the field, that work by apparently by-passing these normal field requirements.
