The role of photoperiod and irradiance level on growth and development of lettuce was investigated at two stages of plant growth. Vegetative dry weights and the number of leaves are primarily influenced by length of the photoperiod with most growth occurring under long photoperiods and high irradiances. Leaf area of mature plants was related to the input of light energy suggesting a photoregulatory process in the plant that optimizes leaf size for intercepting a constant amount of photosynthetic light.Key words: Lactuca sativa, growth, development, photoperiod, irradiance, light energy
