SEASONAL STRESSORS. “Throughout its growing range, this evergreen species is exposed to subfreezing temperatures that range from -10 to -30°C during the winter and high temperatures exceeding 30°C during the summer. These extremes are generally indicative of conditions leading to photo-oxidative stress, especially during periods of high irradiance and reduced CO2 fixation, when the primary sink for the removal of electrons from PSI is limited.” (Eastern White Pine).
