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

Plant hormones are master regulators of plant growth and development. Better knowledge of their spatial signaling and homeostasis (transport and metabolism) on the lowest structural levels (cellular and subcellular) is therefore crucial to a better understanding of developmental processes in plants. Recent progress in phytohormone analysis at the cellular and subcellular levels has greatly improved the effectiveness of isolation protocols and the sensitivity of analytical methods. This review is mainly focused on homeostasis of two plant hormone groups, auxins and cytokinins. It will summarize and discuss their tissue- and cell-type specific distributions at the cellular and subcellular levels.
