1. Promote photosynthesis
Chlorophyll in crops mainly includes chlorophyll a and chlorophyll b, which are important pigments to absorb light energy in photosynthesis. Under the catalysis of glutamine tRNA reductase (GluTR), glutamate generates glutamine tRNA, which is then catalysed by a variety of enzymes and multi-step reactions to generate chlorophyll a and chlorophyll b, thereby enhancing the crop's absorption of light energy and improving the efficiency of photosynthesis.
2. Improve crop quality
Nitrate in the human body can be reduced to toxic nitrite. Most of the nitrate taken in by the human body comes from vegetables, so it is important to reduce the nitrate content in vegetables. Some studies have shown that the absorption of glutamate by many crops can significantly reduce the nitrate content in crops, inhibit the absorption of nitrate by crops roots, and also increase the content of soluble sugar and vitamin C in crops,
3. Improve seed germination rate and crop stress resistance
Glutamic acid can generate polymer -poly-glutamic acid under polymerization reaction. polyglutamic acid has strong water retention property in soil, is a promoter of seed germination, has obvious drought resistance and seedling promotion effect, can effectively improve the germination rate and seed vitality of crops, polyglutamic acid can promote the growth of crop roots, promote the growth of root hairs and new roots, and improve the ability of underground parts to absorb nutrients, It can significantly improve the stress resistance of crops.
