Allometric relations of sycamore maple (Acer pseudoplatanus) and its red leaf cultivar (A. pseudoplatanus "Atropurpureum") in street and park habitats of novi sad (Serbia, Europe)

Abstract

© 2019 Society of American Foresters. Adaptability and allometric relations of Acer pseudoplatanus and A. pseudoplatanus "Atropurpureum" at different urban sites are investigated in this work via the diameter at breast height (dbh), tree height, and crown width measurements, which served as ordinary least-squares regression model inputs. Differences between A. pseudoplatanus and A. pseudoplatanus "Atropurpureum," as well as intraurban variations of trees growing at different urban site categories (park and street) and location in the same urban site category with different urban morphology characteristics, were noted. The strongest allometric relations were noted for crown width/tree height and tree height/ dbh. Higher uniformity and better linear model fit were obtained for A. pseudoplatanus "Atropurpureum." Based on allometric relations with dbh as the predictor variable, trees growing in parks were shorter and had a wider crown than street trees, whereas the same tree proportions were observed in A. pseudoplatanus.
