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.

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

Introduction Welcome to your preparation guide for this week’s practical lab session! Before we get hands-on with the equipment, it is crucial to understand the physiological principles that allow us to measure plant health, light environments, and photosynthetic rates. In the upcoming practical, we will demonstrate three essential scientific instruments: The Konica Minolta SPAD-502 Chlorophyll Meter The LI-180 Spectrometer The LI-6800 Portable Photosynthesis System Rea

Introduction Gibberellic Acid-3 (GA-3) is a naturally occurring plant growth regulator that causes a variety of physiological effects, including the stimulation of seed germination and stem elongation. GA-3 occurs naturally in the seeds of many species and is produced commercially by growing Gibberella fujikuroi fungus cultures, followed by extraction and purification. Presoaking seeds in a GA-3 solution can trigger rapid germination in many types of highly dormant seeds. In

Whether it is a seedling pushing through the soil or a fruit ripening on a branch, every movement a plant makes is orchestrated by complex chemical messengers known as Plant Growth Regulators (PGRs) or Phytohormones. Derived from the Greek word hormaein, meaning "to excite," these natural molecules work in minute concentrations to produce substantial physiological changes. What Defines a Phytohormone? Unlike animals, plants do not have specialised glands for hormone product

1. Introduction Growth analysis is a mathematical expression of environmental effects on the growth and development of crop plants. Classical growth analysis typically requires the destructive harvesting of representative sets of plants over several weeks, making it impossible to follow the same plant throughout an entire experiment. This practical introduces a non-destructive, single-harvest alternative by utilizing a space-for-time substitution. By examining a single frond

Introduction & Theory Plant propagation through stem cuttings is a fast and cost-effective technique that maintains the genetic traits of the parent plant. The success of this method depends heavily on the rapid formation of adventitious roots. This process is regulated by plant hormones called auxins, which stimulate cell division in the stem's vascular tissues. Indole-3-butyric acid (IBA) is a widely used synthetic auxin because of its stability and effectiveness across man
