It is set that the use of retardants are effective regulation of growth, morphogenesis, productivity and slowing the germination of tubers during storage products. The number of leaves per plant, weight of rаw and dry matter of leaves and their area increased because of better tillering for the actions of the drugs. That is one of the main preconditions enhance photosynthetic activity of plants. Changes of phytometric and mezostructure indexes of leaves and increase of chlorophyll content for the actions of the drugs contributed to the photosynthetic activity of leaf apparatus, because of that was increase of the net productivity of photosynthesis and increase productivity of the culture. The use retardant of tebuconazol was the most effective. Treatment retardants of potato tubers during the release of dormancy led to decrease in the intensity of germination, that contributes to the preservation of products.
