It leads to an increase in the absorption of nutrients, which in turn increases the economic yield, medicinal compounds, and the percentage of oil in the seeds, as well as vitamin C, phenols, flavonoids, and total tannins in the seeds, and increases the plant’s tolerance to harsh environmental conditions. Also, the use of this acid increased by spraying it on the vegetative body of the plant because it is one of the antioxidant substances that leads to encouraging vegetative and fruiting growth, and its effect on plant growth is similar to the effect of growth regulators that encourage plant growth and also reduce stress resulting from temperatures and toxins, as well as lead to increased secretion of organic acids From the roots to the soil, which leads to an increase in most nutrients, which are released slowly and absorbed by plants, and its role also in protecting cells from the harmful effect of temperature and light oxidation and stimulating cell division.
