Yes I've tried looking this up via my own research unfortunately I've not had much success/found much info.

I know some seeds require light to germinate others need darkness. My question is what seeds need light to germinate, what seeds need darkness for germination?

The only thing I know needs light to germinate is lettuce.

The others I have no idea here is my list below...

Greens (collards, radicchio, cress, kale, mustard greens)

root veggies (carrots, beets, turnips, radish) (daikon lg. white Asian radish)

zukes and cukes
tomatoes, peppers, eggplant

winter squash (kabocha, butternut, acorn etc.)
melons (watermelon, cantaloupe etc.)
beans (lima, snap, filet bean etc.)

None of your list *needs* light to germinate although they will germinate in light if they have to.

RE: what seeds need light to germinate?

Only a few flower varieties require light for germination. Lettuce does not require light either.


RE: what seeds need light to germinate?

Recently began to think the amount of light is directly related to the required depth of planting the seed.
See depth page 54 of the attached book.

Here is a link that might be useful: Light/depth

Try this site. Tom Clothier's Garden Walk and Talk. Click on the seed germination database you need.
It will tell you all you need to know.
