Gallenmüller, Friederike Feus, Amélie Fiedler, Kathrin Speck, Thomas Geometry of rose prickles having failed and not failed. <p>Prickles classified as failed have snapped off in mechanical tests. Prickles where the Kevlar loop slipped off are classified as not failed. For <i>Rosa arvensis</i> data obtained with traction parallel to the stem (force direction “1”) are pooled and for <i>Rosa arvensis</i> ‘Splendens‘ type I and II data obtained with traction at 45° (force direction “2”) are pooled.
