Grow it, harvest it, measure it, calculate it. In this four-week practical, AGR3301 students grow choy sum in sand culture under LED lights, harvest plants at 14, 21 and 28 days after sowing, and work out seven growth parameters from their own data: LAI, AGR, CGR, RGR, NAR, SLA and SLW. The full lab manual, with methods, worked examples and report guide.

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

Your task is to present and analyse the findings from our recent spectrometer experiment in the physiology lab. You will evaluate and compare the light readings taken from the top tier and the bottom tier, interpreting what these differences mean for plant physiological processes. Create a video about 10-15 min, with you or your group talking about the spectrometer values below. Use creative thinking to fashion your video, it could be a podcast interview style, a forum, a sho

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
