Abstract
Heat stress is a major threat to global agricultural productivity, with rising temperatures due to climate change exacerbating this challenge. This article examines the impact of heat stress on crop yield, focusing on the physiological and biochemical processes affected in plants. High temperatures disrupt photosynthesis, respiration, and water relations, leading to reduced growth and impaired reproductive development. The article explores various crops, including wheat, rice, and maize, highlighting their specific responses to heat stress. It also discusses strategies to mitigate the adverse effects, such as breeding heat-tolerant varieties, employing agronomic practices, and utilizing biotechnological interventions. Through a comprehensive understanding of the mechanisms behind heat stress and the implementation of effective solutions, it is possible to enhance the resilience of crop plants and sustain agricultural productivity in the face of global climate change.
