Hydrogen Peroxide and Seed Germination

On the relationship between hydrogen peroxide and seed germination

covers the metaplasia of heaven and earth, the reproduction of all things, and the germination of seeds, which is related to vitality. Among them, hydrogen peroxide is particularly crucial in seed germination. The relationship between the two is quite worth exploring.

The husband of the seed contains the opportunity of life, and it will come out when the time comes. However, the process of germination is controlled by various factors. Hydrogen peroxide, although this substance is small, the influence of seed germination cannot be underestimated.

Looking at various experiments, an appropriate amount of hydrogen peroxide can promote seed germination. What is the reason? Because hydrogen peroxide can regulate the physiological metabolism in the seed. In the dormant state of the seed, an appropriate amount of hydrogen peroxide can break the system of dormancy and initiate the order of germination. It can stimulate the activity of enzymes in seeds. If it is an amylase, it can promote the hydrolysis of starch into sugar, supply energy for seed germination, and make embryos nourish and germinate.

And hydrogen peroxide can participate in the redox reaction in seeds and regulate the redox state in cells. A moderate oxidizing environment is conducive to the expression of genes in seeds, enabling the synthesis of related proteins, and assisting the growth of embryos and the germination of root buds.

However, the extreme will reverse. If the amount of hydrogen peroxide is too large, it will harm the germination of seeds. Excessive hydrogen peroxide can cause the accumulation of reactive oxygen species in seeds, damage the structure and function of cell membranes, increase the permeability of membranes, extravasate intracellular substances, and disturb the normal physiology of seeds. It can also break the redox balance in cells, causing damage to biological macromolecules such as proteins and nucleic acids, and hindering the germination process of seeds.

Therefore, if you want to make good use of hydrogen peroxide to promote seed germination, you must carefully observe its concentration and duration of action. Precise regulation allows hydrogen peroxide to generate benefits and avoid harm in seed germination. In this way, the best effect of seed germination can be obtained, which is beneficial to agriculture, horticulture and other industries, and helps all things thrive and grow orderly.
