Use: Biochemical studies a new and efficient plant growth-promoting agent at very low concentrations, which can significantly increase vegetative plant growth and facilitate fertilization and currently some plants use the growth regulator, compared with a safe. No phytotoxicity, low effective concentration using the high activity and can improve the characteristics of the plant nutrients can promote IAA (indole acetic acid) synthesis, ABA (abscisic acid) and ethylene, promote cell elongation and expansion and thus promote Plant growth effect (varies with the plant species), can inhibit aging, break dormancy and promote seed germination, promote leaf growth, promote root growth, induction of bisexual flowers and female flowers. After in different regions, different crops Daejeon Application tests showed that the wheat can yield more than 10%, corn yield more than 20%, more than 10 percent increase in rice, strawberries, watermelon, yield more than 20 percent of tobacco, citrus, orange yield 15%
