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 of galangal...

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 many plant species....
