Summary: It was studied the mesostructure organization of leaf apparatus and pigment content of leaves under applica-tion of growthregulators with different mechanism of action – esfon (2-HEFC) (0,2%) (ethylene producer) and Epin (0,1 ml/l) (growth stimulator) on broad bean plants. The plant growth regulators treatment on broad beans led to the thickening of leavesdue to increase in the growth of columnar and spongy leaf parenchyma. Growth regulators influenced on the formation of stomatal apparatus of broad beans leaves in different ways. The inhibi-tory compound esfon caused a decrease in the number of lower epidermal cells and stomata with a simultaneous increase in the stomatal cells area. The application of stimulator compound Epin led to an increase in epidermal cells, without differences in the number of stomata but the area of stomatal cells increased significantly. It has been established the enhancement of photosynthetic processes due to increase in the chlorophyll content in assim-ilative cells of leaves under esfon on broad beans.
