4. Notable functions:

Alpha-Naphthyl acetic acid (NAA) is a broad specturm kind of plant growth regulator. It can be translated to target with the flow of nutrition when absorbed through leaves, seeds or the tender epidermis of plants. The main functions are as below:

1) Accelerate the division and enlargement of cells;

2) Induce the formation of adventitious roots;

3) Keep flowers, keep fruits setting, prevent fruits dropping;

4) Adjust sex ratio of flower (male flowers: female flowers);

5. Target crops:

1) Cereal: Promote effective tillering, increase thousand seed weight, increase yield;

2) Cotton: Reduce the dropping of cotton boll and increase the weight of cotton boll;

3) Fruits and vegetables: Keep flower, keep fruits setting, improve quality;
