Keeping busy until spring

The idea of a plant being able to conduct photosynthesis during freezing temperatures was a novel idea to me. The researchers in this article wanted to see how lingonberries were able to recover to a photosynthetic state during periods of mild temperature during winter months. They tested temperature, photoperiod, and preceding frost for effects on the lingonberry, and what they discovered surprised me. Extreme cold slowed down the recovery, however the berries were able to come back and maintain photosynthesis even at freezing temperatures. These berries amaze me! The more I learn, the more I realize I don’t know. Check out their findings in the article listed below. CM Fairbanks
