Title:Main Title: Root growth and distribution data Selhausen [2017] Upper and Lower Rhizotron facility (maize)
Description:Abstract: The root development was measured by a minirhizotron system (Bartz Technology Corporation). A digital camera with a visible frame of 16.5 mm (vertical) by 23.5 mm (horizontal) was used to capture the root images from both the left and right sides of the rhizotubes. The camera was positioned using an indexing handle at 20 observation locations in the tubes. Four series of five locations were taken at 1 to 1.5, 2 to 2.5, 3 to 3.5, and 4 to 4.5 m from the access facility wall. Within a series, the centers of the images were located at 0.04, 0.12, 0.26, 0.38, and 0.5 m from the side of the series. Repeatable observations could be performed at the same locations with fixed intervals on the index handle. The information on rooting depth, root counts, and root length was obtained from the images by using Rootfly (Wells and Birchfield, 2009).
