EFFECT OF RETARDANTS ON WHEAT GROWTH PROCESSES AND ANATOMICAL CHARACTERISTICS

Abstract

The article presents the results of research of growth processes and anatomical indicators of wheat culture of the variety Kraevid, depending on the treatment with the growth-regulating preparation – tebuconazole (0,5% and 1%). The tebuconazole was treated by spraying the aerial part and introduction through the root system. It has been established that the use of tebuconazole of different physiological-active concentrations (1% and 0.5%) in different methods of introducing into the plant (through the root and through spraying) led to a slowing of linear growth and inhibition of the root growth of wheat plants. The most distinct effect was observed with the use of 1% tebuconazole when the retardant was treated through the root. Treatment of wheat plants with tebuconazole through root and spraying caused significant changes in water metabolism and photosynthesis of plants: the linear size of stomata decreased, that led to reduction of the stomata area. It was found that when the tebuconazole was fed through the root, the transpiration intensity was higher than in the variant with the spraying of plants.
