Plant Growth Inhibitors: Understanding Abscisic Acid and Ethylene

Plant growth is not just about stretching upward; it is also about knowing when to stop, conserve energy, and survive harsh conditions. Understanding how plants regulate these processes through natural growth inhibitors is essential for anyone interested in botany, horticulture, or agronomy. This text-based course provides a clear, step-by-step introduction to the science of plant hormones, focusing specifically on abscisic acid (ABA) and ethylene. You will explore how these chemical messengers control seed dormancy, leaf fall, fruit ripening, and stress adaptation, and how modern agriculturalists use synthetic regulators to manage crops efficiently in changing climates. What you will learn: Understand the foundational concepts of phytohormones and plant growth regulation; Analyze the synthesis, transport, and physiological roles of abscisic acid (ABA) in drought and stress tolerance; Explore how ethylene regulates fruit ripening, senescence, and plant defense mechanisms; Examine the practical applications of exogenous growth regulators in modern agriculture and post-harvest management; Discover how modern climate resilience strategies leverage plant hormone pathways to protect crops from extreme weather. The course begins with essential botanical terminology and foundational biological concepts before moving into detailed studies of hormone pathways and real-world agricultural applications. Through clear written explanations and practical scenarios, you will build a solid working knowledge of plant physiology. Designed for beginners, students of agriculture or botany, and home gardeners, this course requires no prior background in advanced biochemistry.
