Morphology of long axes and geometry of the tested rose prickles.

<p>The specified values are medians and lower and upper quartiles (in brackets). Number of samples are n = 36 (<i>Rosa arvensis</i>), n = 141 (<i>Rosa arvensis</i> ‘Splendens‘ type I) and n = 149 (<i>Rosa arvensis</i> ‘Splendens‘ type II). All differences are significant (Kruskal-Wallis test and Dunn’s test, p < 0.001) with exception of the mean axis diameter compared between long axes of <i>Rosa arvensis</i> and <i>R</i>. <i>arvensis</i> ‘Splendens‘ type I, where no significant differences are found.</p><p>Morphology of long axes and geometry of the tested rose prickles.</p>
