S-Abscisic Acid (ABA) Functions and application effect
1.what's S-Abscisic Acid(ABA)?
S-Abscisic Acid (ABA) is a plant hormone. S-Abscisic Acid is a natural plant growth regulator that can promote coordinated plant growth, improve plant growth quality, and promote plant leaf shedding. In agricultural production, Abscisic Acid is mainly used to activate the plant's own resistance or adaptation mechanism to adversity, such as improving the plant's drought resistance, cold resistance, disease resistance, and salt-alkali resistance.
2.Mechanism of action of S-Abscisic Acid
S-Abscisic Acid is widely present in plants, and together with gibberellins, auxins, cytokinins, and ethylene, it constitutes the five major plant endogenous hormones. It can be widely used in crops such as rice, vegetables, flowers, lawns, cotton, Chinese herbal medicines, and fruit trees to improve the growth potential and fruiting rate and quality of crops in adverse growth environments such as low temperature, drought, spring cold, salinization, pests and diseases, increase the yield per unit area of medium and low-yield fields, and reduce the use of chemical pesticides.
3. Application effect of S-Abscisic Acid in agriculture
(1) S-Abscisic Acid enhances resistance to abiotic stress
In agricultural production, crops are often subjected to abiotic stress (such as drought, low temperature, salinity, pesticide damage, etc.).
Under sudden drought stress, the application of S-Abscisic Acid can activate cell conduction on the plasma membrane of leaf cells, induce uneven closure of leaf stomata, reduce transpiration and loss of water in the plant body, and improve the plant's water retention capacity and tolerance to drought.
Under low temperature stress, the application of S-Abscisic Acid can activate cell cold resistance genes and induce plants to produce cold resistance proteins.
Under soil salt collapse stress, S-Abscisic Acid can induce a large accumulation of proline, an osmotic regulating substance in plants, maintain the stability of cell membrane structure, and increase the activity of protective enzymes. Reduce the Na+ content per unit dry matter weight, increase the activity of carboxylase, and enhance the salt tolerance of plants.
Under the stress of pesticide and fertilizer damage, S-Abscisic Acid can regulate the balance of endogenous hormones in plants, stop further absorption, and effectively eliminate the adverse effects of pesticide and fertilizer damage. It can also improve the cooperation and accumulation of anthocyanins and promote crop coloring and early maturity.
2) S-Abscisic Acid enhances the resistance of crops to pathogens
The occurrence of pests and diseases is inevitable during the growth stage of plants. Under the stress of diseases, S-Abscisic Acid induces the activation of PIN genes in plant leaf cells to produce protein enzyme inhibitors (flavonoids, quinones, etc.), which hinder the further invasion of pathogens, avoid damage or reduce the degree of damage to plants.
(3) S-Abscisic Acid promotes color change and sweetening of fruits
S-Abscisic Acid has the effect of early color change and sweetening of fruits such as grapes, citrus, and apples.
(4) S-Abscisic Acid can increase the number of lateral roots and adventitious roots of crops
For crops such as cotton, S-Abscisic Acid and fertilizers such as humic acid are dripped into the water, and the seedlings emerge with dripping water. It can increase the number of lateral roots and adventitious roots of cotton seedlings to a certain extent, but it is not obvious in cotton fields with high alkalinity.
(5) S-Abscisic Acid is mixed with fertilizer to balance nutrients and play a certain role in weight loss.
4.Application functions of S-Abscisic Acid
Plant "growth balance factor"
Promote root growth and strengthen roots, promote the growth of capillary roots; promote the growth of strong seedlings and increase yield; promote sprouting and flower preservation, increase fruit setting rate; promote fruit coloring, early harvest, and improve quality; enhance nutrient absorption and improve fertilizer utilization rate; compound and increase efficiency, and reduce common drug negative effects such as fruit deformity, hollows, and cracked fruits.
Plant "resistance induction factor"
Induce crop disease resistance and improve disease resistance; improve crop resistance to adversity (cold resistance, drought resistance, waterlogging resistance, salt and alkali resistance, etc.); alleviate and reduce crop drug damage.
Green and environmentally friendly products
S-Abscisic Acid is a pure natural product contained in all green plants, mainly obtained through microbial fermentation, non-toxic and non-irritating to humans and animals. It is a new type of efficient, natural green plant growth active substance with broad application prospects.
5. Application scope of S-Abscisic Acid
It is mainly used in rice, wheat, other major food crops, grapes, tomatoes, citrus, tobacco, peanuts, cotton and other vegetables, fruit trees and oil crops. It plays an important role in regulating growth, promoting rooting and promoting coloring.
