اثر تابش‌های ترموگرافیک بر بهبود انتقال آب و مواد در آوندهای چوبی تحت شرایط تنش حرارتی

Abstract

Heat stress is one of the most critical limiting factors for plant growth, leading to reduced water uptake and transport capacity, increased transpiration, and enhanced production of reactive oxygen species (ROS). These factors collectively disrupt plant metabolism and ultimately reduce yield performance. TIR contributes to alleviating these challenges by reducing water surface tension, increasing molecular mobility, and decreasing hydraulic resistance in the xylem, thereby enhancing water flow and preventing cavitation. Furthermore, TIR influences stomatal regulation by facilitating the opening and closing of stomata, which results in improved water use efficiency and a better balance between transpiration and water uptake. Additionally, TIR has been found to enhance the activity of antioxidant enzymes, thus reducing oxidative stress induced by high temperature. Empirical studies on various crops such as wheat, rice, and maize have demonstrated that TIR can play a vital role in enhancing plant tolerance to heat stress. However, there remain challenges such as the high cost of equipment and the need for further research to optimize the implementation of this technology. This review article explores the latest scientific findings and highlights the importance of TIR in improving plant resilience to thermal stress.
