Figure 2From: X-ray micro-computed tomography in willow reveals tissue patterning of reaction wood and delay in programmed cell death 2D transverse X-Ray CT scans. A single representative image from the stack reconstructed from the X-ray CT scanning of each stem segment. Each tree is either RW induced (T1, T2 and T3) or a control grown without induction (C1, C2 and C3). Regions of interest assessed for voxel intensity and distribution, TW, OW and NW are highlighted in red. High voxel intensity, and therefore 554 great X-Ray attenuation, is visible as lighter regions whereas regions of low voxel intensity are visible as darker regions. Scale bar = 4mm.Back to article page
