Humic fulvic acid benefits on photosynthesis
The application of the fulvic acid in the foliage spray or in the nutrient solution can cause an increase in the content of the chlorophyll. Even can prevent the yellowing under the condition of the lack of the cation.The fulvic acid promotes the absorption of the magnesium or the iron. So that the content of the chlorophyll is increased. Which leads to the enhancement of photosynthesis and increases the accumulation of dry matter.
Humic fulvic acid benefits on respiration
There are many studies on the effect of fulvic acid on respiration. Fulvic acid has more promoting effect on respiration than humic acid. Fulvic acid can directly participate in respiration. Under the condition of normal O2 concentration, fulvic acid enters the plant and acts as H receptor.
The transformation of phenols and quinones in fulvic acid molecules is not only the activating agent of oxygen, but also the carrier of H, which improves the redox in plants and strengthens the respiration of plants. Fulvic acid can enter cells and bind to mitochondria, which proves that humic fulvic acid can directly affect respiration.
Fulvic acid with phenolic group and carboxyl group is involved in oxidation-reduction process. Which is similar to the free radical in the form of semi-quinone. Therefore, fulvic acid is very suitable for directly participating in the electron transfer system related to respiration. And can participate in the oxidation-reduction reaction with the transfer metal.
Benefits on enzyme
The fulvic acid can promote the activity of cytochrome oxidase and make the above-mentioned viewpoint further positive.
In addition, fulvic acid can also enhance the disease resistance of fruit trees. Improve the quality of grain, vegetables, melon and fruit, sugar cane, tobacco and other products. It can be seen that fulvic acid has a wide range of effects on plant growth, development, physiology and so on. Therefore, the study of fulvic acid has both theoretical significance and application value.
