Root system changes in response to experimental treatments may he due to a number of factors, which can be separated only by sampling roots of known age. Minirhizotrons allow for video recording of the growth of individual roots; subsequent removal of the minirhizotron would allow sampling of the roots under observation. A design for a removable minirhizotron with mechanically expandable walls is described in this paper, along with the use of laparascopic tools for sampling roofs from removable minirhizotron systems. Laparascopic tools used in conjunction with removable minirhizotrons may be useful in field studies of the effects of root age and experimental treatments on root composition, physiology, and pathology; rhizosphere mycrobial ecology; rhizosphere mineralogy; and the dynamics of mycorrhizal colonization.
