Epigeous Germination

by Sally on April 17, 2010

These are the seeds sown on the 13th April. Now up and stretching to the light through the lid of the propagator so I’ve taken them out and found them their own little sun spot in which to come to in.

They’ve been through a process known as epigeous germination. This specifically refers to the process where the seeds leaves (cotyledons) come up and unfurl as the seedling emerges into the air. The role of the seed leaves is to provide the plant with stored energy until it can start making its own – through the process of photosynthesis.

All seedlings need this initial source of stored energy to draw on but with some, like the pea, the cotyledons don’t emerge with the seedling but remain under the soil. This other type of germination is known as hypogeous.

So small and yet already so perfectly formed and ingeniously designed !

Designed? No… it’s all natural. :)

Nature – No it’s all Nurture ( well until they die – then it’s a ‘design’ flaw !)
