What specifically happens to your plant when they don’t receive enough water? Credit to @sustainableplant for information and picture ・・・ Dehydration
We all know dehydration is “bad” for living things and can lead to stress, illness and death. But what exactly is going on in your plants when they don’t get enough water?
▶️Stomata in leaves close, decreasing photosynthesis
▶️Photosynthesis has an increased chance of creating excited oxygen molecules, hydrogen peroxide and other molecules that can damage plants
▶️Hydrogen peroxide is an important stress signal and can activate a plant’s hypersensitive response, leading to the destruction of damaged cells
▶️Sugar levels in leaves can increase as plants try to maintain photosynthesis with fewer stomata
▶️Plants take in less carbon, slowing growth and cell division
▶️Plants may focus on producing stress-fighting molecules or root growth rather than flowering
Most plants use a photosynthesis process that causes up to 97 percent of the water taken up from the soil to be lost by transpiration from the leaves. That’s a lot of water movement! And important to keep in mind when growing your plants. Steady levels of leaf water reduce stress, reduce chances for disease and encourage growth.
