Classroom Modified Split-Root Technique and Its Application in a Plant Habitat Selection Experiment at the College Level
Elliott, Shannon S.; Winter, Peggy A.
Bioscene: Journal of College Biology Teaching, v37 n2 p23-29 Dec 2011
The split-root technique produces a plant with two equal root masses. Traditionally, the two root masses of the single plant are cultivated in adjacent pots with or without roots from competitors for the purpose of elucidating habitat preferences. We have tailored this technology for the classroom, adjusting protocols to match resources and time periods characteristic of undergraduate teaching laboratories. Our classroom modified split-root technique is presented here through detailed instructions as part of an eight-week college laboratory experience. Adapted from the literature on root competition, this exercise also enables students to determine how Sugar Ann English pea plants allocate their root masses when experiencing competition, and more specifically, the applicable habitat selection model. This novel laboratory experience offers hands-on activities for students to learn more about the structure and development of roots, root competition, the crucial role of roots in plant survival, and plant cultivation.
