The role of humic acid in the growth of higher plant structure

Humic Acid function to Plant,The effect of humic acid on crop growth has a similar effect on auxin. Many researchers have used isolated organs to test auxin in place of auxin using bioassays of auxin or other physiological effects. This method can in turn be used to determine the biological activity of humic acid.

Because the isolated organs used for auxin bioassay are relatively young, such as tomato root, pea root and wheat coleoptile, their optimum concentration is lower than that of humic acid, which can effectively stimulate the activity of crop auxin. . Different components of humic acid have different effects on tomato roots.

Humic acid is more effective in promoting plant growth. Fine studies have shown that humic acid promotes cell elongation more than cell division, while fulvic acid has a more pronounced effect on cell division. Our company researchers have also found that humate can increase the water absorption of red maple trees after transplantation, and thus the fluid flow in the room plants increases.

In addition, humic acid can also reconstitute rice callus and increase the number of cells. All of the above experiments indicate that humic acid has auxin activity. Humic acid promotes seed germination and has a GA-like activity in this respect.

Humic acid with cytokinin and active humic acid containing abscisic acid can germination of non-illuminated hi light seeds and anaerobic seeds, and has no side effects on normal light seed germination, which is sufficient to show that this process is related to the regulation of phytochrome.

Humic acid has cytokinin activity in promoting the expansion of radish leaves. Humic acid has abscisic acid activity in inhibiting stomatal opening and promoting superoxide dismutase activity.

Humic Acid function to Plant to increases nutrient uptake, drought tolerance, and seed germination. It increases the microbial activity in the soil, making it an excellent root stimulator. Humic acid increases the availability of nutrients in our fertilizers and in those already existing in your soil. It will help to aerate the soil from the inside. It will also help to lower the pH of the soil to a more neutral level and will flush high levels of salts out of the root zone, all of which will help to promote better plant health and growth.
