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

The specified values are medians and lower and upper quartiles (in brackets). Number of samples are n = 36 (Rosa arvensis), n = 141 (Rosa arvensis ‘Splendens‘ type I) and n = 149 (Rosa arvensis ‘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 Rosa arvensis and R. arvensis ‘Splendens‘ type I, where no significant differences are found.
