NAA-Na 61-31-4 1-Naphthaleneaceticacid, sodium salt
Sodium a-naphthaleneacitic acid (NAA-Na)is one kind of broad-spectrum plant growth regulators, it can enter plant body through plant leaves and skin together with nutritions. It can promote root differentiation and formation, speed up branches and cuttings rooting growth, induce flowering, accelerate chlorophyl synthesis,prevent flower and fruit-dropping.Meanwhile sodium a-naphthaleneacitic acid can increase the ability of resistance and thus increase yield well.
