Natural abscisic acid is a white crystalline powder, easily soluble in methanol, ethanol, acetone, chloroform, ethyl acetate and chloroform, etc., but hardly soluble in ether, benzene, etc., with a water solubility of 3-5 g/L (20°C). Abscisic acid has good stability. After two years of storage at room temperature, the content of active ingredients remains basically unchanged, but it should be sealed and stored in a dry, cool, and dark place. Abscisic acid aqueous solution is sensitive to light and is a strong light decomposition compound.
Natural abscisic acid and auxin, ethylene, gibberellin, and cytokinin are listed as the five major plant hormones. It can improve the drought resistance and salt tolerance of plants, and is extremely useful for the development and utilization of low- and medium-yield fields, afforestation, and desert greening. value. ABA is also an effective inhibitor to inhibit seed germination, so it can be used for seed storage to ensure the storage quality of seeds and fruits. In addition, ABA can also cause the rapid closing of leaf stomata, which can be used to preserve flowers, adjust flowering period, promote rooting, etc., and has greater application value in flower gardening. The study of ABA and its response genes can reveal the molecular process of plant stress resistance, thereby laying the foundation for the targeted enhancement of crop adaptability to the environment.
The physiological role of abscisic acid is mainly to cause dormancy and promote shedding. Treating germinated seeds with abscisic acid can make them dormant. This inhibitory effect on germination can be counteracted or reversed by treatment with gibberellin or cytokinin. Abscisic acid can antagonize the effect of gibberellin instead of long-day sunshine, causing long-day plants to bolt and bloom. It also enables some short-day plants to bloom under non-induction cycle conditions. On the contrary, several effects of abscisic acid can also be offset by gibberellin. Abscisic acid has the effect of antagonizing gibberellin and cytokinin in plants. Abscisic acid can counteract the germination-promoting effect of gibberellin, but continuing to increase the concentration of gibberellin cannot overcome the role of abscisic acid and restore the germination-promoting effect.
1.Promote shedding
Accelerate the shedding of plant organs
2.Inhibit growth
Inhibit the growth of whole plants or isolated organs, and inhibit cell division and elongation. It inhibits the elongation and growth of coleoptiles, twigs, roots and hypocotyls.
3.Promote dormancy
Applying ABA to the vigorously growing branches of these woody plants will cause the buds to dormant to extend their dormant period.
4.Cause stomata to close
Spraying plant leaves with ABA water solution can close the stomata and reduce the transpiration rate.
5.Regulate seed embryo development
The normal development and maturity of embryos and the inhibition of premature germination can accelerate the formation of certain special storage proteins.
6.Increase resistance
ABA can induce the re-synthesis of certain enzymes and increase the cold resistance, waterlogging resistance and salt resistance of plants.

Application
(1) Abscisic acid is an effective inhibitor of seed germination
(2) Abscisic acid can promote the storage of seeds and fruits, especially the accumulation of storage proteins and sugars.
(3) Abscisic acid can enhance the ability of plants to resist cold and frost, and can be used to help crops resist low temperature and cold damage during early spring and to cultivate new crop varieties with strong cold resistance.
(4) Abscisic acid can improve the drought resistance and salt tolerance of plants, and it has extremely high application value for helping humans resist more and more drought environments, developing and using low- and medium-yield fields, and afforestation.
(5) Applying exogenous abscisic acid to wheat etc. can inhibit stem elongation, increase ear weight, and resist crop lodging.
Value
1. Promote the ability of plants to balance water and fertilizer and coordinate metabolism in the body, which can effectively regulate the root, crown and vegetative growth and reproductive growth of plants, and play an important role in improving the quality and yield of crops.
2. Inhibition of transpiration, can be used to preserve the freshness of flowers, or to prevent wilting during the transportation of crop seedlings transplantation and cultivation.
3. Abscisic acid is a pure natural plant growth regulator, which can improve the growth quality, seed setting rate and quality of crops in poor growth environments such as low temperature, drought, spring cold, salinity, pests and diseases, and increase the yield per unit of medium and low yield fields, and reduce The amount of chemical pesticides.
4. Abscisic acid can be widely used in the green construction of urban lawns, gardens, etc., in water-saving agriculture, facility agriculture, and restoration and reconstruction of ecological vegetation in the western region.
