I thought we should look again this morning to see if any more seedlings were emerging. Well, there’s not many emerging, but as I walked across the field I could see more seedlings in this situation than yesterday. The seedling is lifting the crust above it by the force of the elongating or straightening of the hypocotyl.

I moved over several rows and found the first seedling that has its cotyledons above the soil surface. You can see that the soil crust has been pushed back. The cotyledons will split apart, as they are starting to do now and by later today they will be separated. Pretty neat, huh?
