Gibberellic Acid 4+7 (GA4+7) is a mixture of gibberellin A4 and gibberellin A7. It is a growth regulator that can stimulate the rapid growth of rhizomes and induce certain plant leaves. It can stimulate the rapid growth of rhizomes, induce mitosis of certain plant leaves and increase the germination rate of seeds.
GA4 and GA7 are two of the most active ones among gibberellins. Because these two kinds of gibberellins have similar molecular structures, they are difficult to separate and often exist in the form of a mixture GA4 + 7.
