Abstract
In the environment of low temperature and poor light,light compensation point,light saturation point,dark respiration rate,maximum photosynthetic rate and photosynthetic quantum efficiency were measured in seeding and flowering stages with different capsicum varieties.The light compensation of tolerance variety was lower than others.With the decrease of temperature and light intensity,net photosynthetic rate of leaves decreased gradually.
