Frozen seeds can last 50 to 20,000 years!

Thread starter #1
Hi -- I was just listening to Terri Gross's always wonderful "Fresh Air" program on NPR. She was interviewing the guy who started The Global Seed Vault nine years ago, where they store the world's crop biodiversity in a giant tunnel in a mountain just 700 miles south of the North Pole.

The who runs the place said they store the seeds at about 1 degree Fahrenheit, and that at that temperature they can last from 50 to 20,000 years.

Since I occasionally see discussions here about seed storage, I though I'd pass that along.

These things will be very valuable at some point in the future. Although they might simply be treated as spoils of war instead of distributed properly. Or they could end up being forgotten, I suppose.

Not surprising. In 2005 a Judean Date Palm seed found in an archaeological dig in Isreal was grown. And about ten years ago, scientists managed to extract three viable plant embryos from immature seeds that had been buried 125' below the frost line in squirrel hibernation dens and managed to grow them into healthy plants which produced 100% viable seed - and they'd been carbon dated to just shy of 32,000 years old. Although that was out of something like 500,000 or 600,000 seeds...

I wonder if they evacuate the air and replace it with nitrogen or perhaps a noble gas at those seed vaults?

If you listen to the interview at the link (I found it fascinating), the designer said they designed it to be as low cost and low maintenance as possible. It's just a giant tunnel into a mountain. No running water, no bathrooms, no N2 gas. Just a big, cold hole. ;)

I found it on the NPR One app. Still looking for my earbuds...

I have been freezing cannabis seeds since 1977. Many still germinate at 100% rates. Yet, here on this forum people constantly trash talk my posts and say that Cannabis beans cannot or should not be frozen. Many rags and books say that as well. Yet, the truth is that they can be frozen and thawed, and they grow just fine.

As far as I know (and I'll admit that I could be mistaken), most (maybe all?) of those "preservation against disaster" wide-variety seed storage vaults that are around the world store their contents in a cold-temperature environment. Some of them are located in arctic conditions, and I don't think they bother to heat them for the comfort of their caretakers. I read a brief article about one a while back that included a photo, and the guy was wearing a parka.

If longterm cold storage was a guaranteed kill, most of the inhabitants of this planet would have never been born. It has, after all, gone through several ice ages, lol.

Yup. If they didn't, it would have never survived the ice age.....
