Abstract<br />
Coarse root systems of four different fruit tree species from sou<strong>the</strong>rn Africa were completely<br />
excavated and semi-automatically digitized. Spatial distributions of root length were determined<br />
from <strong>the</strong> digitally-reconstructed branching systems. Fur<strong>the</strong>rmore, <strong>the</strong> fractal characteristic of <strong>the</strong><br />
coarse root systems was shown by determining <strong>the</strong> box-counting dimensions. These quantitative<br />
methods revealed architectural differences between <strong>the</strong> species, probably due to different<br />
ecophysiological strategies. For fine root samples, which were taken be<strong>for</strong>e digging out <strong>the</strong> whole<br />
systems, fractal analysis of <strong>the</strong> planar projections showed no significant inter-species differences.<br />
Methodologically, <strong>the</strong> study underlines <strong>the</strong> usefulness of digital 3-D reconstruction in root research.
