ImageJ Setup and Scaling: Participants installed the ImageJ software and configured image scaling by setting rulers to establish consistent pixel-to-millimetre units. Counting and Measuring Roots: Researchers utilised multi-point tools for root counting and freehand tracing for curvature measurement. Ea

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

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):
