Description

(-)-Cis, trans-Abscisic Acid CAS NO 14398-53-9 is a key plant hormone (phytohormone) that plays a central role in regulating plant growth, development, and stress responses. Its primary commercial value lies in its ability to induce stomatal closure, enhance drought tolerance, and promote seed dormancy, making it a critical tool for agricultural research and crop management. This high-purity compound is essential for plant physiology studies, agrochemical formulation development, and biostimulant production for the global agricultural and horticultural sectors.

Application

• Plant Stress Physiology Research: Fundamental studies on abiotic stress responses, including drought, salinity, and cold tolerance mechanisms.
• Agrochemical & Biostimulant Formulation: A key active ingredient in developing next-generation products aimed at improving crop resilience and water-use efficiency.
• Seed Technology: Used to study and manipulate seed dormancy and germination processes for improved storage and synchronized planting.
• Controlled Environment Agriculture (CEA): Application in hydroponic and greenhouse systems to manage plant growth and optimize resource use under stress conditions.
• Plant Tissue Culture: Employed in media to regulate growth and morphogenesis in vitro.
• Post-Harvest Management: Research into delaying senescence and wilting in fruits, vegetables, and cut flowers to extend shelf life.
