Why can a 30-metre coconut palm lift water without a pump? The full Lesson 3 lecture follows water from soil to root, stem, leaf and air, then on to humidity and vapour pressure.

Watch the class demonstration of three seed quality tests in one session: the tetrazolium viability test, the rolled-towel germination test and seed moisture content by rapid oven drying and slow sun drying, with the reasons behind each step.

Soak potato cylinders in sucrose, weigh them, and find the concentration where mass stops changing. That point reveals the tissue's water potential.

How does a dry seed wake up and become a seedling? Lesson 2B of AGR3301 Crop Physiology covers water uptake, hormones, food mobilisation in barley, light control through phytochrome, and seedling establishment.

How does water reach the top of a 30 m palm with no pump? Learn water potential, transport and vapour pressure deficit (VPD), step by step.

Why does a living seed sometimes refuse to germinate? Lesson 2A of AGR3301 Crop Physiology follows the seed from formation to dormancy, with examples from rice, oil palm, cocoa and the remarkable coco de mer.

Every crop starts as a seed that must survive storage, wait out dormancy and then germinate. This post follows the journey from seed to seedling, covering seed structure, storage, dormancy, germination and establishment, with links to Malaysian crops such as rice and oil palm.

When does a plant become a crop? What does "physiology" really mean? This first lecture introduces the three tasks of crop physiology (understand, diagnose, act) and the key ideas of growth, development and differentiation, with pitcher plants, Pokémon and a 120-metre redwood along the way.

Designed to fit the 500-character limit in your Wix editor) Welcome to Lesson 1B of Crop Physiology (AGR3301). This post breaks down the mathematics of crop growth analysis, from measuring total dry weight to calculating the 7 key parameters like LAI, CGR, and RGR. Discover how to read a sigmoid growth curve, understand leaf efficiency, and see exactly why agronomists must use natural logarithms (ln) to accurately track continuous plant growth

All crops are plants, but not all plants are crops. While plant physiology explains how an individual plant works, crop physiology uses that knowledge to predict and manage yield, quality, and resilience at the field level. This post breaks down the three essential tasks of crop physiology: understanding cellular mechanisms, diagnosing plant functions, and managing environmental responses. Discover how applying these principles allows agronomists to diagnose field issues and

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
