Understanding the Effects of Extreme Heat on Plants
Extreme heat can have devastating effects on plants, causing them to suffer from heat stress, scorched leaves, and even death. When temperatures rise, plants lose water rapidly through a process called transpiration, where they release water vapor into the air through their leaves. This can lead to a range of problems, including:
Heat Stress and Its Consequences
Heat stress occurs when plants are unable to cool themselves down, causing their internal temperature to rise. This can lead to a range of symptoms, including wilting, yellowing leaves, and reduced growth. Heat stress can also make plants more susceptible to disease and pests, further compromising their health and survival.
Water Loss and Drought
In extreme heat, plants lose water rapidly, leading to drought-like conditions even in areas with adequate rainfall. This can cause plants to go into survival mode, producing fewer flowers, fruits, and seeds, and reducing their overall growth and productivity. Drought can also lead to soil degradation, reducing its water-holding capacity and making it more challenging to grow plants in the future.
The Benefits and Drawbacks of Daily Watering
