Spatial patterns of root branching and actinorhizal nodulation in Discaria trinervis seedlings

, : Spatial patterns of root branching and actinorhizal nodulation in Discaria trinervis seedlings. Symbiosis Rehovot 29(4): 329-341

The spatial patterns of root branching (topology) and actinorhizal nodulation of Discaria trinervis seedlings (collected in March 1995) under natural and controlled conditions were analysed. The link, i.e. the root segment between either two branching points, or between a meristem and a branching point, was used as a structural unit of roots. Nodulated field plants displayed a random model of root topology and experimental plants without root symbionts a herringbone model (Fitter, 1991).
