Abstract
The detrimental effect of high heat on plant development is expected to have a widespread negative impact on plant growth as a result of global warming. Climate change is posing an increased threat of climatological anomalies, such as elevated temperatures, which might result in a severe reduction of agricultural yield and global famine. High temperature is an important physical stress which restricts crop growth, metabolism, and yield throughout the world. Plant growth and development depend on the number of temperature-sensitive metabolic processes. The degree and duration of high temperatures, as well as the plant species, all influence plant responses to high temperatures. It has now become a major source of concern for agricultural producers. Adaptive, avoidance, and/or acclimatization strategies are found in plants to cope with extreme temperature. This article focuses on the impact of high temperature stress on crop plants.
