New #graperesearch finds that evaluating #coldhardiness is key to understanding physiological changes during dormancy and spring phenology. Manipulating temps to study increasing hardiness, the authors say, might unintentionally prolong time to budbreak. botany.fyi/QSzM7I

Time to budbreak is not enough: cold hardiness evaluation is necessary in dormancy and spring...

AbstractBackground. Dormancy of buds is an important phase in the life cycle of perennial plants growing in environments where unsuitable growth conditions
