Figure 10From: Comparative transcriptome analysis coupled to X-ray CT reveals sucrose supply and growth velocity as major determinants of potato tuber starch biosynthesisPotato tuber segmentation and volume calculation. A) Two dimensional X-ray images illustrating that potato tubers can be distinguished from the surrounding soil. The histogram shows that segmentation is possible. The red bar indicates the grey level threshold selected. B) Linear regression of X-ray calculated and real volume measurements confirming the accuracy of X-ray CT calculated volumes.Back to article page
