S-abscisic (S-ABA) is also known as abscisic acid. It is a highly effective plant growth regulator, and is listed as one of the five major natural plant growth regulators recognized by the world, along with auxin, gibberellin, cytokinin, and ethephon. It can not only improve the drought resistance, cold resistance, salt and alkali resistance and disease resistance of plants, but also significantly improve the yield and quality of crops. It is a highly active and powerful plant growth regulator.
Characteristics of S-abscisic
1. "Growth balance factor" of plants
S-abscisic is a key factor in balancing the metabolism of endogenous hormones and related growth-active substances in plants. It has the ability to promote the balanced absorption of water and fertilizer by plants and coordinate metabolism in the body. It can effectively regulate the root/crown and vegetative growth and reproductive growth of plants, and plays an important role in improving the quality and yield of crops.
2. "Resistance-inducing factor" of plants
S-abscisic is a "messenger" that activates the expression of stress-resistant genes in plants, and can effectively activate the stress-resistant immune system in plants.
It has the ability to strengthen the source and enhance the comprehensive resistance of plants (drought resistance, heat resistance, cold resistance, disease and insect resistance, salt and alkali resistance, etc.). It plays an important role in drought resistance and water conservation, disaster reduction and production protection, and ecological environment restoration in agricultural production.
3. Green and environmentally friendly products
S-abscisic is a product contained in all green plants. This product is obtained through microbial fermentation with high purity and high growth activity; it is harmless and non-irritating to humans and animals. It is a new type of efficient and natural green plant growth active substance.
S-abscisic packaging, transportation and storage
The packaging must be moisture-proof and light-proof, and dark plastic bottles, tin-platinum paper plastic bags, light-proof plastic bags and other packaging materials should be used. Long-term storage should be ventilated, dry and light-proof.
S-abscisic mechanism of action
When under adverse stress, S-abscisic transmits adverse information between cells and induces the plant body to produce various resistance capabilities.
Under soil drought stress, S-abscisic activates signal transduction on the plasma membrane of leaf cells, inducing uneven closure of leaf stomata, reducing transpiration and loss of water in plants, and improving plant drought resistance.
Under cold stress, S-abscisic activates cell cold resistance genes and induces plants to produce cold resistance proteins. Generally speaking, the endogenous S-abscisic content of plant varieties with strong cold resistance is higher than that of varieties with weak cold resistance;
Under the stress of pests and diseases, S-abscisic induces the activation of PIN genes in plant leaf cells, produces protease inhibitors to prevent further damage by pathogens or pests, avoids damage or reduces the degree of damage to plants;
Under the stress of soil salinity, S-abscisic induces plants to enhance the osmotic regulation ability of cell membranes, reduces the NA+ content per kilogram of material, increases the activity of PEP carboxylase, and enhances the low-salt ability of plants;
Under the stress of pesticide and fertilizer damage, it regulates the balance of endogenous hormones in plants, stops further absorption, and effectively eliminates the adverse effects of pesticide and fertilizer damage; Under normal growth conditions, S-abscisic induces plants to enhance photosynthesis and absorb nutrients, promotes the transport and accumulation of substances, increases yields, and improves quality.
S-abscisic functional characteristics
It can significantly improve the growth quality of crops, induce and activate more than 150 genes in plants to participate in regulating the balanced growth of modern substances and the synthesis of nutrients, enhance the ability of crops to resist drought, low temperature, salinity, and waterlogging, effectively prevent the occurrence of pests and diseases, eliminate pesticide and fertilizer damage, and stabilize flowers, preserve fruits, and promote fruit expansion and early maturity;
It can enhance crop photosynthesis, promote the synthesis of amino acids, vitamins and proteins, accelerate the accumulation of nutrients, and has a particularly significant effect on improving quality and increasing yields; after application, seedlings take root quickly, take root more, turn green quickly after transplanting, and have a high survival rate. The crops have vigorous growth throughout the entire vegetative growth period and reproductive growth, strong resistance to stress, and few pests and diseases.
Applicable crops: various food crops, cash crops, vegetables, fruit trees, tea trees, Chinese medicinal materials, flowers and horticultural crops, etc.
