The use of antigibberelins with different mechanisms of action on morphogenesis and production process regulation in the plant Solanum melongena (Solanaceae)

Summary/Abstract: The influence of antigibberelin on the growth, development and productivity of eggplant was investigated. It was established that the use of tebuconazole and chlormequat chloride is a highly effective tool for regulation of morphogenesis and productivity of eggplant. We found that retardants slowed the growth of plants, and increased the number of leaves and leaf area and dry substance weight of the whole plant. Under the influence of Esfon ethylene producers the inhibition of the growth process was not accompanied by increase of the number, weight and area of leaves.Antigibberelin agents caused the thickening of chlorenchyma and the growth of the columnar cells and cell sizes of spongy parenchyma. Under the action of agents the thickness of the upper and lower epidermis of the leaf increased. As a result of mesostructural and morphometric changes of leaf structure under the influence of retardants the leaf index and specific leaf surface density increased.The growth inhibitory agents increased the chlorophyll content in leaves and caused the growth of chlorophyll index in crops.Retardants reduced the content of sugar and starch in leaves because of their enhanced outflow to fruits, the amount of which was predicted to be greater. Under the influence of Esfon the flow of carbohydrates to the acceptor areas was slower.The use of retardants of triazole and onium origin positively influenced the formation of productivity elements of the culture, which led to increase in the fruit yield. The use of tebuconazole was found to be the most effective.
