What is Abscisic Acid Sigma?

The abuse of pesticides and fertilizers has seriously threatened my country’s food safety, international trade, sustainable agricultural development and ecological civilization construction. Green agricultural technology products are highly effective against harmful organisms, safe for humans, animals and non-target organisms, and play an important role in environmental protection and food safety strategies. Vigorously promoting new green agricultural technologies can improve land utilization, reduce agricultural production costs, ensure food safety, promote the quality of agricultural products to meet urban and international demand, increase the added value of agricultural products, and promote vigorous demonstrations and demonstrations of green agricultural technologies. The promotion will completely change the operation mode of agriculture in the past and ensure the sustainable development of agriculture.

Abscisic Acid Sigma (abbreviated as S-ABA or ABA, scientific name: abscisic acid) is an internationally recognized five major types of plant endogenous growth knot substances (auxins, gibberellins, cytokinins, ethylene and abscisic acid), known as the king of plant stress-inducing substances. It can activate or induce the expression of 150 kinds of resistance genes in plants, start the resistance or adaptation mechanism of the plant itself to adversity, improve the drought resistance, cold resistance, disease resistance and salinity resistance of plants, regulate plant growth, and improve the quality of agricultural products. To improve the survival ability of crops under abnormal climate and soil conditions, it can be widely used in the fields of disaster prevention and mitigation of agricultural production, ecological vegetation construction, afforestation, urban landscaping and safe production of agricultural products. Abscisic Acid Sigma is different from the previous exogenous abscisic acid. It is produced by the secondary metabolism of microorganisms. At present, Abscisic Acid Sigma has been used in grape cultivation in the United States, Japan and other places.

Abscisic Acid Sigma Uses

  1. Abscisic Acid Sigma can promote the production of ethylene, advertise fruit ripening, it hinders DNA as well as protein synthesis. The physical features of abscisic acid are as adheres to:
    1. Prevent and advertise growth. The growth of stems, hypocotyls, roots, coleoptiles or leaves was prevented when the concentration of exterior application of abscisic acid was high. When the focus is reduced, it can advertise the rooting of separated cucumber cotyledons and also the prolongation of hypocotyl, accelerate the reproduction of duckweed, and boost the development of parthenocarpic seeds.
    2. Preserve bud as well as seed dormancy. Dormancy is connected to the balance of gibberellin and also abscisic acid in the body.
    3. Promote the shedding of fruits and leaves.
    4. Promote stomatal closure. Abscisic acid can rapidly shut the stomata and also is safe to plants. It is an excellent anti-transpiration representative. An organic examination technique to examine the focus of abscisic acid is to drift the skin of separated fallen leaves on the surface of numerous focus of abscisic acid options. Within a specific variety, the level of stomatal opening and also closing is vice versa proportional to the focus of abscisic acid.
    5. Influence flowering. Under long-day problems, abscisic acid can make strawberry and also blackberry incurable buds dormant as well as advertise flowering.
    6. Influence sex-related differentiation. Gibberellin can make female marijuana plants develop male flowers, as well as this impact can be reversed by abscisic acid, yet abscisic acid can not make male plants develop female flowers.
  2. Natural isomer of Abscisic Acid Sigma. A plant development regulator with a high fondness binding site for abscisic acid on the plasma membrane of faba guard cells. It relates to various physical devices such as seed dormancy, fallen leave shedding, stomatal motion and plant anxiety response. With complicated interactions with several intracellular signaling systems, abscission isoforms can regulate the expression of numerous plant genetics.

Other Applications of Abscisic Acid Sigma

At present, 15 Abscisic Acid Sigma preparation products have been registered in my country, which are mainly used in staple food crops such as rice and wheat, as well as vegetables, fruit trees and oil crops such as grapes, tomatoes, citrus, tobacco, peanuts, and cotton. Coloring plays an important role. The plants used are: ①Vegetables include tomato, pepper, cucumber, eggplant, bitter gourd, cowpea, green bean, lettuce, celery, chrysanthemum, lettuce, rape, cabbage, coriander, etc.; ②Chinese medicinal materials include ginseng, salvia, wheat Winter, Chuanxiong, etc.; ③ Root plants include ginger, potatoes, etc.; ④ Melons include pumpkin, watermelon, melon, cantaloupe, etc.; ⑤ Tea, flue-cured tobacco, leaf tobacco, etc.; ⑥ Crops include corn, soybeans, rice, wheat, etc.; ⑦ Fruit trees Classes include citrus, loquat, kiwi, jujube, pear, cherries, plums, peaches, persimmons, apples, grapes, etc.; ⑧ weak trees, stiff trees (slow growth); ⑨ various woody saplings and branches, etc.; Plant herbs, flowers, cotton, mushrooms, etc. According to statistics, Yunnan, Hainan, Hunan, Hubei, Anhui, Liaoning, Guangdong, Hebei, Shandong, Zhejiang, Jiangsu, Ningxia, Xinjiang, Inner Mongolia, Sichuan and Taiwan are currently using s-induced antibiotics in China; Induced antibiotics are found in Japan, South Korea, the United States, Australia, Canada, Chile, Israel and South Africa. Its application is embodied in the following aspects:

Use Abscisic Acid Sigma to dip the roots, which can improve the survival rate of seedlings. The survival rate of jujube and apricot trees is increased by 35.0% and 33.0% respectively compared with the use of general rooting powder, and the survival rate of landscape tree species is 95.0%.

In the study on the effect of ABA seed soaking on rice growth, development and yield, the quality and yield of rice seedlings after ABA seed soaking were better than those of the control, and the effect of seed soaking with 6.25×10 mol/L was better. , the amylase activity, germination rate, free amino acid content, soluble sugar content, chlorophyll content and effective tiller number were significantly different from other treatments. After seed soaking in ABA solution, the average yield of “Shanyou 63” and “Eryoupeijiu” increased by 7.6% to 12.5% ​​respectively compared with the control, and the yield of the treatment concentration of 6.25 × 10 mol/L was the highest, increased by 12.4% compared with the control, respectively. % and 20.8%. In terms of seed soaking time, the research on the effect of ABA seed soaking on rice growth and yield showed that with 0.1 and 0.3 mg/kg ABA soaking for 24 and 36 h, the quality and yield of rice seedlings were better than those of the control. The yields of the treatments with concentrations of 0.1 and 0.3 mg/kg were 9.5% and 19.5% higher than those of the control, respectively, and the average yield of rice treated with ABA seed soaking was 9.9% higher than that of the control. In the application study of 1% s-pyrucin·indolebutyric acid in rice production, it was shown that 1% Abscisic Acid Sigma·indolebutyric acid WP was sprayed on the seedlings on the seedbed 7 days before rice transplanting, It has the effects of promoting root differentiation, dwarfing seedlings, strengthening seedlings, increasing effective tillering of rice, enhancing plant stress resistance, and increasing yield.

In the application study of Abscisic Acid Sigma in tomato seedling transplanting, it was shown that spraying s-allophane series products can promote plant growth and root development in tomato seedling transplanting production. , enhance plant growth and effectively reduce disease damage. Fruit pressure tolerance, soluble solids content, single fruit quality, fruit set number and yield were improved and improved to varying degrees, especially the number of effective branches per plant, the number of fruit ears, the number of fruit set, and the yield were 6.2% and 6.2% higher than those of the control. 5.7%, 5.9%, and 11.2%, with significant increases.

In the research on the effect of s-induced antibiotics on improving the drought resistance of wheat, it is shown that the use of 0.1% s-induced antibiotics can promote the development of wheat roots under drought conditions and increase the unit area. The number of spikes can significantly increase the 1000-grain weight of wheat, thereby increasing wheat yield. The application effect was best in wheat seed dressing, and the earlier the application time, the more obvious the effect. Liu Gang et al. studied the effect of Abscisic Acid Sigma on water consumption of maize plants, and showed that 0.1% s-inducible foliar spraying treatment could significantly reduce the stomatal conductance and transpiration rate of maize leaves under high temperature and drought, and increase the rate of transpiration. The rate of photosynthesis, thereby reducing plant water consumption and maintaining more plant water holding capacity, can mitigate the adverse effects of drought on crop growth.

In the application study of Abscisic Acid Sigma on Turpan fruit jujube trees, it was pointed out that the use of Abscisic Acid Sigma in 5-year-old fruit jujube trees in the leaf-expansion period, flowering period and fruit-setting period was carried out in stages. Spraying on the surface can promote the balanced absorption of nutrients by the fruiting jujube trees and improve the utilization rate of fertilizers. Compared with the control without spraying, it can obviously promote the differentiation of flower buds and increase the yield and income of fruit set.
