Naphthalene acetic acid (NAA) is a synthetic plant hormone that is used for a variety of purposes in the agricultural and horticultural industries. The following are some of the most common uses of NAA:
1. Promoting root growth: NAA is frequently used as a rooting hormone to stimulate root formation in cuttings. When applied in the proper amount, it can significantly increase the success of propagation.
2. Stimulating fruit growth: NAA is also used as a ripening agent in the production of fruit crops such as apples, pears, and grapes. It helps to promote the development of larger, more uniform fruit.
3. Increasing fruit set: NAA can be used to increase the number of fruit set on a plant. By promoting the development of fruiting bodies, it can improve the overall yield of a crop.
4. Controlling flowering: NAA can be used to control the timing and intensity of flowering in some plants. It is often used to delay or muffle flowering in greenhouse-grown plants to coordinate their development with market demand.
5. Stimulating growth: In some situations, NAA is used as a general growth regulator to increase plant vigor and promote vegetative growth. It can be used on a variety of crops, including vegetables, fruits, and ornamentals.
6. Controlling plant growth: When applied in specific concentrations, NAA can be used to control the height and branching of plants. This is particularly useful in the production of ornamental plants, where uniformity and aesthetics are important.
7. Managing plant stress: Some studies suggest that NAA can help plants cope with various types of stress, such as drought, heat, and disease. Its ability to promote root growth and general plant vigor may make it a useful tool in mitigating the effects of environmental stressors.
Overall, NAA is a versatile tool for plant growers and can be used for a variety of purposes. It is important to carefully follow the manufacturer's instructions for application rate and timing to ensure the desired effects and avoid harming the plants.

1-Naphthaleneacetic Acid (NAA) is a plant growth regulator that has the effect of promoting plant growth and fruit development. It is widely used in agricultural fields such as fruit trees, vegetables, flowers, lawns, etc. In addition, NAA can also be used in forestry, gardens and other fields.
From the perspective of market demand, the prospect of NAA is very broad. With people's increasing awareness of green ecology and environmental protection, consumers' demand for pesticide-free, pollution-free, and organic food continues to increase, which provides a more sufficient market space for the application of NAA. In addition, with the improvement of people's living standards and the transformation of agricultural production methods, the increasing demand for plant growth regulators will also promote the further development of the NAA market.
According to statistics, the annual export volume of NAA is constantly increasing. Taking 2018 as an example, the total export volume of China's NAA reached 1,308 tons, with an export value of 25.95 million US dollars. Mainly exported to the United States, Japan, India, Russia and other countries and regions. Among them, the United States is the main importer of NAA.
In terms of perennial use countries, NAA has been widely used around the world. Including China, the United States, Japan, India and other populous countries, almost all countries have the application of NAA. Among them, China is one of the major countries in the production and export of NAA in the world, and China's NAA production technology has reached the international advanced level.
To sum up, from the perspective of market demand, export volume and perennial user countries, NAA has a very bright prospect. With the increase of people's demand for green ecology and environmental protection and the transformation of agricultural production methods, the market prospect of NAA will be broader. At the same time, China also has great potential in NAA production technology and is expected to become an important promoter of the NAA market in the future.
The development history of 1-Naphthalene acetic acid (NAA) can be traced back to the early 20th century. Initially, the properties of natural auxins were studied by isolating them from plants and microorganisms. However, the amount of isolated auxin is extremely small, and the extraction and purification process is very difficult. Therefore, researchers began to search for synthetic analogs to replace natural auxins.
In 1929, American chemist Sakugoro Kiyomitsu successfully synthesized a substance with a chemical structure similar to natural plant auxin, which he called "naphthalene acetic acid", or NAA. In the 1930s, German scientists Karl Bömer and Harvesleben successfully prepared NAA crystals, which promoted the application of NAA as a plant growth regulator.
In the 1950s and 1960s, with the advancement of chemical technology, it was discovered that NAA could not only promote plant growth, but also improve the yield and quality of fruit trees, vegetables and other crops. Therefore, NAA is widely used in agricultural production and becomes one of the key components of plant growth regulators.
Currently, NAA remains one of the most commonly used plant growth regulators in agriculture, horticulture and plant science research. At the same time, researchers are continuing to search for and synthesize more efficient and environmentally friendly plant growth regulators to meet the needs of agricultural production and ecological protection.
