Non-deep simple morphophysiological dormancy in seeds of the rare alpine/subalpline annual Circaeaster agrestis (Circaeasteraceae).

Summary: Have you ever wondered how seeds survive freezing winters high up in the mountains? Scientists studied a rare mountain plant called Circaeaster agrestis to learn its secrets. They found that its seeds have a special kind of "sleep" called dormancy. To wake up and grow, the seeds need specific temperature changes, a dry resting period, and special plant hormones. This clever trick helps the plant survive harsh mountain weather and sprout only when it is safe!
