A Primer on Plant Hydraulic Physiology for Nursery Professionals

Plant hydraulic physiology, the study of water movement through plants, offers mechanistic explanations for better understanding connections among nursery production regimes, seedling growth, and outplanting performance. Applying plant hydraulic physiology methods and concepts starts with an understanding of flow rates, conductance, and conductivity. Water flow and hydraulic failure in woody plants are affected by the size and arrangement of the xylem, the morphology and allometry of the plant, and the environmental conditions in which the plant is growing. Nursery professionals can predict and manipulate the complex and dynamic responses of seedlings to water stress with knowledge of the plant hydraulic traits. The application of plant hydraulic physiology will help with the efficient and sustainable production of seedlings that can survive in challenging outplanting environments.
