Maximum forces and maximum forces/basal area measured at failure in Asparagus spines.
Figures are generally photos, graphs and static images that would be represented in traditional pdf publications.
Maximum forces at failure were measured in Asparagus falcatus and A. setaceus with traction forces parallel to the stem and with an angle of 45° (toward the apex). Numbers below indicate the number (n) of samples (100% in all tests) having failed. (***: p ≤0.001, Student’s t-test and Mann-Whitney U-test).
