Abstract

The article investigates the morphometric characteristics of the fruits of Acer negundo L. in the conditions of urbanized ecotops of the Mykolaiv region. The materials of the work were the original harvests of ripe fruits of A. negundo, made in anthropogenic habitats. The work uses traditional methods of collection and processing of plant material, laboratory and statistical methods of morphological research. The following carpological parameters of A. negundo were investigated: angle of divergence of mericarps, fruit’s length and width, width of winglet. The determination of the variability of morphological characters was carried out according to the method of S.A. Mamaev. As a result of our research, it was found that A. negundo fruits have the following morphometric characteristics: fruit 3,5±0,02 cm long, 3,2±0,05 cm wide; mericarps at an angle of 25 to 60 degrees (40±1 °), elongated with an elongated wing, the width of which is 1,3±0,03 cm. Based on the study of linear morphological parameters, the phenotypic variability of A. negundo fruits was revealed. The most variable parameters were the wing spread angle and wing width (the coefficient of variation was 29% and 34%, respectively). The most stable morphological parameter is the length of the fruit (6%)
