C3 Plants

Performance Horse Nutrition

A C3 plant is one that produces phosphoglyceric acid (a molecule that has three carbon atoms) as a stable intermediary in the first step in photosynthesis. Over 95% of the plants on earth are C3, including cool-season grasses and legumes. C3 plants may lose energy to photorespiration in hot weather. C3 grasses thrive in cool climates and are dormant in hot climates.
