The Primary Limitation to Photosynthesis Following Low Temperature Stress under High Light
Certain plants which are accustomed to growing under temperate conditions show a distinct inhibition of function when exposed for brief periods to temperatures that are well below that optimal for growth yet above freezing. This chill-induced impairment of metabolism persists for an extended period of time after plants are rewarmed to growth temperatures. In many instances, photosynthesis is the foremost physiological process that displays a loss of activity following a low temperature exposure. Damage to photosynthesis is exacerbated when low temperatures are sustained in the presence of high light intensities.
