Accurate assessment of seed quality is vital for predicting crop performance and ensuring optimal storage. We demonstrate and compare three distinct approaches for assessing the seed viability: 1. Tetrazolium (TZ) Test (Chemical/Quick Test): Learn how to use th

Original video: https://youtu.be/SF1Y8ZnhSg8 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 s

Original video: https://youtu.be/z2XB8EG4VUQ Lecture on: 15 October 2025 This video provides a comprehensive overview of the introductory and foundational practical work for the Crop Physiology (AGR3301) course, covering laboratory safety, formal reporting guidelines, and the first major experiment on Crop Growth Analysis. Lab Essentials and Scientific Reporting The first section focuses on establishing proper conduct and methodology for plant science research. It covers esse

Original video: https://youtu.be/LTqGPldxdbI Lecture on: 13 October 2025 The first part of this lecture establishes the difference between plants (multicellular photosynthetic life-forms) and crops (plants grown in large quantities for commercial purposes). All crops are plants, but not all plants are crops. Key Focus of Crop Physiology Crop Physiology is the study of how plant organs (stems, roots, leaves, flowers, fruits, seeds) function, and the complex chemical processes
