5-Aminolevulinic acid (5-ALA) is an essential substance for organisms to synthesize chlorophyll, heme, vitamin B12, etc. It is also an important organic synthesis intermediate. As a photosensitizer, 5-ALA has a wide range of applications, and is currently mostly used in medicine and agricultural production.
In agricultural production, 5-ALA can regulate chlorophyll synthesis, improve photosynthetic efficiency, and promote photosynthesis. 5-ALA can promote basic physiological activities such as plant tissue differentiation.
5-Aminolevulinic Acid is closely related to the synthesis and accumulation of anthocyanins in fruits and vegetables. 5-ALA treatment can effectively promote the expression of related genes, thereby promoting the early synthesis and accumulation of anthocyanins in the peel and affecting fruit coloration.
Treatment with a certain concentration of exogenous 5-ALA not only significantly increased the anthocyanin content of apple peels and improved the appearance quality, but also increased the soluble solid content and solid-acid ratio of the fruit, thus improving the intrinsic quality. At the same time, the shelf life of the fruit is not shortened, and its color-promoting effect is no less than that of auxin or ethephon, without the latter’s side effects.
Instructions and dosage
*Spray:
- Critical period of growth: recommended concentration is 20-50mg/L
- Color change period: Generally used from the end of fruit enlargement, spray once every seven days, the recommended concentration is 100-200mg/L
*Drip irrigation/flush application:
- After appropriate dilution, apply with irrigation/drip irrigation. the dosage is 600-1000g/ha.
Precautions of 5-Aminolevulinic Acid (5-ALA)
- It is not recommended to be used together with alkaline substances.
- It is recommended to reduce the dosage when used together with plant regulators such as stimulants.
- Pay attention to avoid light and high temperature
