These are the Bean Watch 2008 seedlings this morning.
In this close-up of one of the runner bean seedlings that is just emerging, you can clearly see that the seed leaves (cotyledons, the seed’s food store) have stayed in the soil, and the first leaves to emerge are the first true leaves. This is called hypogeal germination.
In this photo of French bean seedlings, from 2004, you can see that the seed leaves have been carried up out of the soil and expanded. This is epigeal germination.
