Re: HYB: germination data-terms

Christian

I am going to have to disagree with you as well. A seed that has produces a root sprout and fails is the same as an egg that fails to hatch, it is still a failure and these should not be included in a count.  In fact the Diffinition of Germinations is:

"Germination is the growth of an embryonic plant contained within a seed; which results in the formation of the seedling."

So if only a root is produced it is technically a failed germination since it did not result in a seedling.

Good thinking though

If the germination rate is being calculated based upon the number of green seedlings detected at the soil surface this is not technically a germination rate.  Rather this is the number of seedlings which both germinated AND survived to that level of maturity.
