Fig. 2From: Decoupling photo- and thermoperiod by projected climate change perturbs bud development, dormancy establishment and vernalization in the model tree PopulusElongation growth under short photoperiod and different temperatures. Plants were grown for six weeks under short photoperiod (10 h) under high (24/24 °C; D/N), moderate (18/18 °C; D/N), moderate/low (18/12 °C; D/N) and low temperatures (12/12 °C; D/N). a Number of new internodes produced per time point. b Overall increase in shoot height.
