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

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

In this practical, we explore the environmental factors that drive plant productivity by using duckweed ( Lemna spp.) as our fast-growing model organism. This video walks you through Experiment 1: The Impacts of Light Conditions and Nutrient Solutions on Duckweed Growth and Physiological Responses. We investigate how external environmenta

Practical manuals Example of Lab Reports Welcome to the crop physiology practical for the Seed Viability and Seed Moisture Content practical sessions of the Crop Physiology (AGR3301) course! 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 this rapid chemical method to

You will measure plant growth using: Leaf Area Biomass (

Original video: https://youtu.be/vV9NjHA5uOg Welcome to the essential video guide for the AGR3301 Crop Physiology Experiment. In this lab, we shift our focus from traditional land plants to duckweed, a "super-crop" capable of doubling its biomass in as little as 16 to 48 hours. This video will walk you through the entire experimental process, from the initial setup to final data analysis. Phase 1: Materials collection (Day 0) At the Laboratory: 1. Go to the Physiology Lab (Bl
