Scientific adviser GlobalLab asking questions ... discuss?
For me there was always a mystery how plants manage to survive the winter, for example, in the mid-latitudes. Near Moscow visited the January cold, when the temperature dropped to -35 or even -39 degrees Celsius. I remember that once the new year, many cars that were on the street, not start from cold. Even antifreeze does not always help. But what about the underground parts of the plant? Roots, tubers? Well, the roots can go many meters deep. A tubers daffodils, for example, because they spend the winter at a shallow depth?
