Potassium fulvicate can alleviate the effects of biotic and abiotic stress on plant growth, and it can enhance plant stress resistance by improving plant physiological characteristics.
A large number of experiments have shown that under adverse stresses such as water, temperature, salt and heavy metals, potassium fulvicate stimulates the synthesis of proteins and enzymes in various organs of plants, enhancing peroxidase, catalase and superoxide dismutase in plants. and other enzyme activities related to reactive oxygen metabolism, and reduce malondialdehyde and plasma membrane permeability in plants, regulate the content of reactive oxygen species in plants, reduce the degree of peroxidation of membrane lipids, and enable plants to maintain a faster growth rate, thereby maintaining It improves the permeability of cell membranes and enhances plant resistance to drought, cold, salt and heavy metals.
In addition to the above-mentioned effects and functions of potassium fulvicate, potassium fulvicate can also modify the expression of the tonoplast water channel intrinsic protein gene OsTIP in the rice root system to enhance the rice’s ability to resist water stress. At the same time, the physical effect is also an important aspect of potassium fulvic acid in enhancing plant resistance to water stress.
Studies have shown that the addition of potassium fulvic acid can form humic acid aggregates on the surface of plant roots, root epidermal cells and new root hairs, reducing the permeability coefficient of the root system and enhancing its drought resistance.
Not only that, potassium fulvicate can also enhance plant stress resistance by changing the plant growth environment. Another article “The role of potassium fulvicate: changing the plant growth environment to enhance plant stress resistance” will give you a detailed understanding.
