Physiological effects of thiourea on biological performance of plants under drought conditions: II. Enhancement of water use efficiency

Abstract

The greenhouse and field experiments were conducted to evaluate the effect of grain pre-soaking and foliar application of thiourea (TU) and thiourea in combination with Composite (TU+C) – the preparation, containing trace elements iron, cobalt, zinc, magnesium, boron, vitamin PP, but iron, cobalt and boron in the form of biologically active coordination compounds (pat. MD 813), on the photosynthesis intensity, transpiration and productivity of maize and soybean plants. It has been established that the use of TU+C made the improvement of water status, increased the content of assimilating pigments, photosynthesis intensity, water use efficiency, growth and productivity of plants. Pre-treated with TU+C plants distinguished by more economically consumption and enhancement of water use efficiency.
