Abstract
Sycamore maple (Acer pseudoplatanus L.) is one of the most valuable species of Serbia?s noble hardwoods. Based on the results of previous research, it can be concluded that this is a species with a pronounced ecological plasticity and high genetic potential. From the aspect of ornamentalness, one of the most frequent cultivars in urban green spaces and tree rows is the cv ?Atropurpureum?, also known as ?Spaethii? or ?Purpureum?. It is distinguished by dark green leaf adaxials and purple undersides, which give the crown an extraordinarily attractive appearance. The genetic potential of the analyzed mother trees can be used for the mass production of the Acer pseudoplatanus ?Atropurpureum? and Acer pseudoplatanus plants needed for urban green area maintenance and creation of tree rows. Special attention should be paid to the potential of mother trees 5 and 3; their descendants, along with purple leaf undersides, also have high average height values for five-year old plants.
Highlights
The main directions for the reconstruction of the existing species and the creation of new cultivated forms consist of the detection and definition of the desired characteristics, selection of initial material, identification of qualitative and quantitative parameters, study of the methods of inheritance of the selected characteristics, and mass production of the improved planting material (Šijačić-Nikolić et al.. 2006).Sycamore maple (Acer pseudoplatanus L.) is one of the most valuable species of Serbia’s noble hardwoods
2006, 2009a), it can be concluded that this is a species with a pronounced ecological plasticity and high genetic potential, exemplified by a great number of cultivated forms: Acer pseudoplatanus ‘Atropurpureum’; ‘Brilliantissimum’; ‘Variegatum’; ‘Leopoldi’; ‘Flavescens’; ‘Flavo Variegatum’; ‘Worleei’ (Bojović, 1989)
The pronounced phenotype attractiveness of such individuals has led to the synthesis of many of the cultivars used in the mass production of ornamental trees and shrubs
Summary
The main directions for the reconstruction of the existing species and the creation of new cultivated forms (cultivars) consist of the detection and definition of the desired characteristics, selection of initial material, identification of qualitative and quantitative parameters, study of the methods of inheritance of the selected characteristics, and mass production of the improved planting material (Šijačić-Nikolić et al.. 2006).Sycamore maple (Acer pseudoplatanus L.) is one of the most valuable species of Serbia’s noble hardwoods. Based on the results of previous research (Fukarek, 1961; Gudeski, 1984; Tripić, 1988; Bojović, 1989; Ivetić and Tucović, 2003; Šijačić-Nikolić et al.2006, 2009a), it can be concluded that this is a species with a pronounced ecological plasticity and high genetic potential, exemplified by a great number of cultivated forms: Acer pseudoplatanus ‘Atropurpureum’; ‘Brilliantissimum’; ‘Variegatum’; ‘Leopoldi’; ‘Flavescens’; ‘Flavo Variegatum’; ‘Worleei’ (Bojović, 1989). From the aspect of ornamentalness, one of the most frequent cultivars in urban green spaces and tree rows is ‘Atropurpureum’ known as ‘Spaethii’ or ‘Purpureum’.
