Unfortunately, there is information missing in Fig. 3. This figure represents all 4 poplar genotypes and black locust, which are differentiated by the letters (a) to (e). In order to enable addressing the graphics to each tree species and hybrids, the figure caption should be read like this:
“Fig. 3 Progression of root collar diameter (mm) and height (cm) of the hybrids (a) P. “AF2”, (b) P. “Fritzi Pauley”, (c) P. “Hybride 275”, (d) P. “Max 1” and (e) R. pseudoacacia over a period of 4 years in mixtures and in pure stands. Error bars represent standard error of the means. Different letters (a, b) represent significant differences between mixed and pure stands for each year.”
