A common method of seed initiation

But, in fact, all of these are methods that are commonly used to help seeds start growing.A typical seed consists of a plant embryo encased in a hard seed coat.To start growing,it needs to emerge or sprout from inside this shell.This process is called germination.But just as it would be hard for you to get out of a jail cell with no windows and no doors,the embryo might need a little help escaping from its seed prison,and any process that makes this easier by wearing down the seed coat is called scarification.
