The increasing frequency and intensity of heat waves, along with sudden temperature fluctuations, are causing rising levels of heat-induced stress in plants<\/strong><\/em>, particularly in agricultural systems exposed to extreme temperatures. This type of thermal stress directly affects crop physiological processes, reducing growth, yield, and overall product quality. Preparing crops to withstand these conditions is not only an adaptation strategy to climate change but also an essential practice for maintaining the sustainability and profitability of agricultural systems.<\/p>\n

When plants are exposed to temperatures above their optimal range, heat stress in plants<\/strong><\/em> disrupts the balance between photosynthesis and respiration, increases water loss through transpiration, and promotes the formation of reactive compounds that damage cellular membranes. Under these conditions, agronomic management must focus on strengthening crop physiology before, during, and after periods of thermal stress to improve resilience and recovery capacity.<\/p>\n

What Is Thermal Stress and How Does It Affect Crops?<\/h2>\n

Thermal stress occurs when ambient, soil, or plant tissue temperature exceeds the plant\u2019s adaptive capacity.<\/p>\n

Under extreme heat conditions, stomata tend to close to prevent excessive water loss, which limits CO\u2082 uptake and reduces photosynthesis. As a result, carbohydrate production declines, directly affecting plant growth and fruit development.<\/p>\n

High temperatures also affect protein and enzyme stability, interfere with nutrient uptake and assimilation, and accelerate phenological cycles, leading to irregular flowering, flower abortion, and smaller or lower-quality fruits.<\/p>\n

If preventive measures are not taken, these effects translate into significant economic losses.<\/p>\n

Agronomic Strategies to Prepare Crops<\/h2>\n

There is no single solution, but rather a combination of practices that collectively enhance plant tolerance in an integrated manner.<\/p>\n

 <\/p>\n

Soil management<\/h3>\n

Well-structured soils with good moisture retention act as thermal buffers. The incorporation of organic matter improves aeration, microbial activity, and water availability for plants.<\/p>\n

The use of organic or plastic mulches also helps reduce evaporation, stabilize soil temperature, and minimize heat-related water stress.<\/p>\n

 <\/p>\n

Plant nutrition<\/h3>\n

Nutritionally balanced crops respond more effectively to thermal stress.<\/p>\n

Certain nutrients play a key role in stomatal regulation, cellular membrane integrity, and water transport:<\/p>\n
