Phenylalanine function on plants

1. Promote fruit coloration

When fruits comes to mature, chlorophyll will be destroyed or converted into Carotenoids , which faded the fruit original color ,meanwhile,anthocyanin combined with saccharides transfer into stable Anthocyanin which largely accumulating in vacuoles,as a result of natural colorful shining fruits. Phenylalanine is the precursor substances of anthocyanin , could directly synthesize anthocyanin and accumulate its content in a short time,thus benefits the forming of Anthocyanin and promote fruit’s natural coloration and sweetness in advance.

Phenylalanine , as a precursor substances of protein synthesis ,forming proteins through connecting peptides in various organs of crops, increase the synthesis rate of protein and its content in grains.

2. Enhance the plant immune system to resist stress condition: draught , freezing,pests, salt-alkaline

Phenylalanine could promote Lignin’s synthesis, by increasing the thickness of cells’ wall to strength the resistance when insects tries to penetrate the cells wall.Improve the resistance of crops to diseases and pests,At the same time, the strong stems of crops enhance the resistance to lodging, largely protect crops normal and healthier growth.

Phenylalanine as a functional fertilizer could be largely found in compound amino acid 

fertilizer , its content ranges from 5%-12%, will naturaly promoto fruits coloration and rippening in advance. 

 The application method, dosage and application interval could be adjustable to different period of fruits' growth. Such as:

grape tree:  

fruit set stage  600-800 times dilute into water and spray on leaves 7 days /time

fruit-inflating, 600 times dilute into water and spray on leaves  3-5 days /time and flushing apply at the same time according to fruits color change

fruit-rendering  500 times dilute into water and spray on leaves 3-5 days /time  and flushing apply at the same time according to fruits color change

and fruit ripeness 500 times dilute into water and spray on leaves 3-5 days /time
