Abstract

When growing native perennial grasses for traditional range and pasture or for advanced biomass energy systems, it is helpful to understand the role seed structure plays in its establishment. This activity discusses both seed structure and seedling emergence in monocots. Through active learning elements, photos, and text, students will discover the basic anatomy of seeds and the function of each structure. The process of seedling emergence is presented in detail including the difference between emergence in cool and warm season grasses. Questions to test student understanding are placed throughout the activity.The education material is designed for introductory level college students and is also useful for extension education.
