Sure about that? How about the exceptions noted?
"this rule applies to a range between 5 and 14 percent" (Harrington 1972, Roberts 1979)

In a nutshell, that's my point exactly. Drying them too much, or using a dry storage packet to artificially remove moisture (like those packets in prescriptions) isn't optimal, according to biology. We dry the seeds to harden the outer shell (which holds-in the moisture) and prevent mold in our seed storage jars. Not to dehydrate the embryo.

Zero. If exposed to air, and the moisture escapes, the embryo will die. A dry seed shell is not the same as a dry embryo. The membrane(s) covering the embryo retain moisture and carbohydrates (food for the emerging cotlydons) Optimal temperatures, warmth and ambient humidity (water) trigger the germination process.
Rusty Trichome Reviewed by Rusty Trichome on . Seed question... What's up guys....not sure if this is the right forum, I'm not new to growing but thought this question may also relate to someone who is new. But out of curiosity, will a seed that has a tiny hole in it germ?? Its seems viable based on the squeezing method, and I have a ton of seeds like this and was just wondering. Thanks Rating: 5
