Alanine: increase the synthesis of chlorophyll, adjust stoma, and resist the germs.
Arginine: enhance the root system development, is the precursor of the plant endogenous hormone polyamine synthesis, to improve the salt tolerance of the crop.
Aspartic acid: improves seed germination, protein synthesis, and provides nitrogen for growth during stress periods.
Cysteine: containing amino acid that maintain cell function and act as antioxidants sulfur.
Glutamate:reduce nitrate content in crops;Improve seed germination, promote leaf photosynthesis, and increase chlorophyll biosynthesis.
Glycine: has a unique effect on crop photosynthesis, conducive to crop growth, increase the content of crop sugar, natural metal chelating agent.
Histidine: regulate stomatal opening and provide precursors of carbon skeleton hormones, catalytic enzymes for mitogen synthesis.
Isoleucine and Leucine: precursor substances that resist salt stress, improve pollen activity and germination, aromatic aroma, etc.
Lysine:enhance chlorophyll synthesis and increase drought resistance.
Methionine: a precursor to the synthesis of ethylene and polyamines, an intrinsic hormone in plants.
Phenylalanine: a precursor that promotes the synthesis of lignin and anthocyanin.
Proline: increase the tolerance of plants to osmotic stress, improve the resistance of plants to stress and pollen activity.
Serine: participate in cell tissue differentiation and promote germination.
Threonine: improve tolerance and insect pests, improve humification process.
Tryptophan: precursor of synthesis of endogenous hormone auxin indoleacetic acid to improve the synthesis of aromatic compounds.
Tyrosine: increase tolerance and increase pollen germination.
Valine: increase seed germination rate and improve crop flavor.
The above amino acid function are sorted out according to some literature and data in domestic and abroad, only for reference.
