Micropropagation is a biotechnology used to clone rare or commercially valuable plant species in vitro. A researcher wants to investigate how the concentration of the plant growth regulator auxin (specifically indole-3-butyric acid, IBA) in the nutrient agar affects the root development of vanilla orchid (Vanilla planifolia) explants.
Design a laboratory investigation to determine if increasing the concentration of IBA increases the number of roots produced per explant. Your answer should include experimental details and follow the CORMS experimental design protocol.
