Lecture on: 27 October 2025

This essential lecture dives into the foundational concepts of seed biology and the critical process of germination in Crop Physiology (AGR3301). Understanding seed anatomy and viability is vital for successful crop establishment.

Seed Structure and Classification We begin by examining the seed's biological function for propagation and its major components: the embryo, food reserves, and the protective seed coat. We clarify the structural differences between:

Endospermous Seeds: Seeds that retain the endosperm tissue as the main food reserve, often surrounded by the aleurone layer (e.g., Maize/Corn).

Non-Endospermous Seeds: Seeds where the endosperm tissue is absorbed by the cotyledons, which then become the primary food reserve (e.g., Broad Bean).

We also explore the classification for storage: Orthodox (tolerant to low moisture/cold) and Recalcitrant (desiccation-sensitive).

Seed Quality and Germination Discover the criteria for Seed Quality, focusing on Viability (ability to germinate) and Vigor (ability to produce healthy plants).

Keywords: Seed Germination, Seed Structure, Endospermous Seed, Non-Endospermous Seed, Seed Viability, Orthodox Seed, Recalcitrant Seed, Epigeal, Hypogeal, Crop Physiology, AGR3301, Plant Reproduction.
