Application of amino acid biostimulant hormone Ⅱ
Although polypeptides, oligopeptides and amino acids are gradually decomposed by proteins, oligopeptides have unique physiological functions (growth regulation, disease resistance, etc.) that amino acids do not have, and are more easily absorbed by plants without consuming their own energy. Oligopeptides and polypeptides are also endogenous hormones and play an important role in plant development. The mechanism of action of polypeptide hormones is very complex. Oligopeptides alone can have thousands of different combinations.
