The Role Of Amino Acids In Plant Growth

- Dec 03, 2018 -

Amino acid (amino acid) : general term for a family of organic compounds that contain amino and carboxyl groups. The basic constituent unit of biological functional macromolecular protein is the basic substance of protein needed for animal nutrition.


Amino acids play three roles in plant growth:

1) supplementary sources of organic nitrogen nutrients;

2) chelating agent of metal ions. Amino acids have the function of complexation (chelation) of metal ions, and it is easy to carry the medium and micro elements (calcium, magnesium, iron, manganese, zinc, copper, molybdenum, boron, selenium, etc.) needed by plants into the plant body to improve the utilization rate of various nutrients.

3) enzyme preparation. Amino acids are promoters and catalysts for the synthesis of various enzymes in plants and play an important role in plant metabolism. However, amino acids are easily assimilated and decomposed by bacteria in the soil, so they should not be used as base fertilizers in the soil. Instead, they are made into foliar fertilizers, which are sprayed on leaves to allow plants to directly absorb amino acids and other elements through the foliar surface.
