Size of seed time of germination

[xdrix]

I have sow a few seed of squash
Seed tall
Seed medium and
Little seed.
I'm note that the little seed is the first seed to germinate.
I think that a little seed could be germinate most easily than a tall seed.
What do you think?

Might be an effect of water absorption, faster for small seeds.

Finaly the plant with the more big seed is the more vigorous.The important is to selected a seed with a big reserve of nutrient.
But she has not been the firt to germinate.
