Seed treatment with S-Abscisic Acid is indeed highly effective in preventing seed rot and seedling decay in wheat and rice, significantly boosting germination rates while simultaneously delivering multiple benefits to crop growth.
**Core Functions of S-Abscisic Acid**
**S-Abscisic Acid Enhances Seed Germination Potential:** It strengthens seed germination vigor—particularly for aged seeds, where the improvement in germination rates is pronounced. It promotes the rapid emergence of a dense network of capillary roots shortly after germination, resulting in a more developed root system for the seedlings. This enhances their capacity to absorb water and nutrients, thereby fundamentally mitigating issues of seed rot and seedling decay caused by weak rooting and poor vitality.
**S-Abscisic Acid Boosts Stress Resistance and Disease Prevention:** As a plant stress-inducer, it preemptively activates the crop's internal stress-response and immune systems. This enhances the resistance of wheat and rice to adverse conditions—such as low temperatures, waterlogging, and saline-alkali soils—thereby reducing the likelihood of seed rot and seedling mortality in unfavorable environments. Furthermore, it triggers the crop's disease-resistance mechanisms, minimizing the incidence of diseases during the seedling stage and further preventing seedling decay.
**Using S-Abscisic Acid to Cultivate Robust Seedlings and Boost Yields:** Seedlings treated with S-Abscisic Acid exhibit superior overall quality; following transplanting, they recover their vigor more rapidly and demonstrate higher survival rates. This leads to an increase in effective tillers, laying a solid foundation for subsequent yield increases. In rice cultivation, its application can boost yields by 5% to 15%—with hybrid rice varieties seeing increases ranging from 7.8% to 11.1%—while also improving quality metrics such as grain chalkiness.
