In this inquiry activity students work in groups to investigate allelopathy via research, using the scientific method to plan and carry out an experiment, and creating a formal written report and oral presentation.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"A new report in the journal Biochemistry and Molecular Biology Education describes a laboratory activity meant to help students understand allelopathy – a type of chemical warfare used by plants to secure the resources needed to grow. In this process, plants release biochemicals that affect the growth or development of neighboring plants. It is a common tactic of invasive plant species. The mechanism has also been used in agricultural production systems as a sustainable and organic way to manage weeds and soil fertility. For example, horseradish produces the molecule sinigrin, which is hydrolyzed in the presence of the enzyme myrosinase to generate allyl isothiocyanate, or AITC. AITC has been shown to have allelopathic effects on lettuce, including reduced and delayed seed germination rates, decreased root hair growth, and decreased root length. Mustard green also contains AITC and is widely utilized to control weed growth in current agriculture production..."
