Fig. 1.

Mean petiole characteristics (length, basal diameter, Young's elastic modulus and dry mass) of the tallest leaves on the parent rosette for plants of ten genotypes of Potentilla reptans subjected to spectral shading and mechanical stress treatments. Only treatment means are shown for which the data from the ten genotypes were combined. Bars indicate standard errors (n=10, for the number of genotypes). Further statistical analysis is provided in Table 1.
