Effect of Plant Growth Regulators on Thermal Use Efficiency Indices and Yield of Wheat (Triticum aestivum L.) Varieties under Terminal Heat Stress and Changing Climate
Terminal heat stress, characterised by a rapid rise in ambient temperature, is one of the major limiting factors for wheat productivity during the reproductive and grain-filling stages. A field experiment was conducted to evaluate the influence of plant growth regulators on heat use efficiency, helio-thermal use effici...
