ABA Storage Solution is a 0.1M aqueous solution of abscisic acid (ABA), a key plant hormone, formulated for stable storage and use in plant biology and agricultural research. It maintains ABA's integrity against degradation from light, temperature, or chemical reactions, ensuring efficacy in experiments. Primarily, it is used to study and manipulate plant stress responses by simulating drought conditions, allowing observation of adaptations to water scarcity. The solution elucidates ABA's role in regulating stomatal closure to reduce transpiration water loss. It is also applied in seed dormancy studies to explore ABA's influence on germination. In crop improvement, it supports development of drought-resistant varieties through analysis of ABA-mediated stress tolerance mechanisms. Suitable for long-term storage of plant samples in physiological and biochemical studies.
