Effect of gibberellin on morphogenesis, formation of photosynthetic apparatus and yield of tomatoes

V. Kuryata V. Rogach O. Buinyi

Application of gibberellin (gibberellic acid, GA3) at the budding stage signifi cantly increased the leaf index, number of leaves per plant, leaf mass, leaf surface area and optimized the chlorenchyma development of tomatoes. The results of the research indicate that gibberellic acid led to increase yields of tomatoes due to formation of a more powerful donor sphere, the temporary deposition of carbohydrates and nitrogen containing compounds in vegetative organs, followed by the active reutilization of these substances for the carpogenesis needs. Enhancement of tomato yield is realized by increasing in values for average fruit weight and number of fruit per plant.
