Does Hydrogen Peroxide Hurt Plants
On the effect of hydrogen peroxide on plants
The role of hydrogen peroxide in plants, there are many opinions. Either it is harmful to plants, or it is beneficial. Try to discuss it in detail today.
Hydrogen peroxide has strong oxidizing properties. If applied to plants in excess, its strong oxidizing properties can damage the structure of plant cells. Cell membranes, the barrier of cells, are eroded by hydrogen peroxide, the integrity of the membrane is lost, resulting in the extravasation of intracellular substances and physiological disorders. For example, in plant roots, if exposed to high concentrations of hydrogen peroxide, the epidermal cells of the roots are damaged, the absorption of water and nutrients is blocked, and the plants are in a state of wilting.
However, an appropriate amount of hydrogen peroxide is also beneficial to plants. When plants grow, they often encounter adversity, such as pathogen invasion and drought stress. At this time, hydrogen peroxide will be naturally produced in plants to defend against foreign enemies. Appropriate application of exogenous hydrogen peroxide can simulate the plant's own stress response and induce the plant to produce a defense mechanism. For example, by activating the antioxidant enzyme system in plants, superoxide dismutase, peroxidase and other activities are enhanced to remove excessive free radicals in the body and reduce oxidative damage. And hydrogen peroxide can regulate plant growth and development and promote seed germination. At appropriate concentrations, it can break the dormancy of seeds, enhance the metabolism of embryonic cells, and successfully break through the seed coat and improve the germination rate.
Studies have shown that in some plants, low concentrations of hydrogen peroxide can promote photosynthesis. It can regulate the opening and closing of stomata, make stomata moderately open, increase carbon dioxide intake, and provide sufficient raw materials for photosynthesis. At the same time, it affects the content and activity of photosynthetic pigments in chloroplasts, improves the efficiency of light energy capture and conversion, and then promotes the accumulation of photosynthetic products, which is conducive to plant growth.
All in all, hydrogen peroxide has a unique impact on plants. The key lies in the control of concentration. Reasonable application can help plant growth; excessive amount will harm plants. Therefore, farmers and growers should use it carefully, and determine its concentration and dosage according to plant species and growth stages, in order to obtain its benefits and avoid its harm.
