Experimental set-up of the measurement panel in the field. Similar panels without a roof were used in climate cambers. (A) Row-wise measurement of 20 wheat leaf replicates. Here, it is visible how threads are passing the first and second reverse rollers. (B) Close up view of a leaf tip attached by a hairpin. (C) The 20g counterweight and third reverse roller. (D) Wheat micro plots and the installed measurement panels with white beads and a near-infrared camera in front. The first three beads on the left were used for reference measurements. The panel was north facing to avoid shading of the investigated plants. The panel roof was installed to prevent confounding effects by raindrops and snow on the beads.
