These are natural chemical messengers that control a plant's growth, development, and movement at minute concentrations. PGR Classification Plant hormones are broadly classified into two groups based on their pr

Original video: https://youtu.be/v-xTdfeac20 Lecture on: 3 November 2025 This lecture, part of the Crop Physiology (AGR3301) course, provides a deep dive into the properties of water, the movement of water within the plant (transport), and the fundamental concept of Water Potential. Water Properties and Transport. We begin by reviewing the unique characteristics of water, focusing on its role in plant function: 1. Polarity and Bonding: Water's polarity leads to hydrogen bondi

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/QXD5rnNXvfg Lecture on: 22 October 2025 Welcome to the essential guide on determining leaf area—a critical measurement in plant physiology and crop growth analysis! Accurate leaf area data is vital for calculating parameters like Leaf Area Index (LAI) and Net Assimilation Rate (NAR). In this video, we guide you through the setup and procedure for three common methods used to measure leaf area in the laboratory: 1. Graph Paper Method (Manual):

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
