Abstract

This article presents data about variability of morphological features of Rosa canina L. fruits. The work materials are herbarium and the results of measurements of fruits of 20 R. canina individuals on 20 test areas in urbanized ecotopes (the parks of Mykolaiv city), in ecotopes as a part of agricultural landscapes (in the vicinity of Shevchenkove village), and in ecotopes with small anthropogenic transformation of flora (Pryingulskyi regional landscape park). As a result of our investigation, we found the following carpological feature of R. canina. In the environment of the Northern Black Sea region R. canina shapes the fruits with the dimension of length from 0,8 to 3,0 cm (the mean is 1,5±0,01 cm) and with the dimension of width from 0,5 to 2,0 (the mean is 1,1 ±0,01 cm). The mass of fruits over a wide range varies from 0,2 to 3,2 g. The nuts’ dimension of length is from 0,3 to 0,5 cm (the mean is 0,4±0,01 cm) and the dimension of width is from 0,1 to 0,5 cm (the mean is 0,3±0,01 cm). The average amount of nuts in a fruit is 25 pieces. The mass of 1000 nuts is 18g. The defined carpological feature of R. canina meets norms. The most constant carpological features of R. canina is the width of a fruit and the length of a nut with the 13-17 % mean of variability. The length of a fruit, the amount of nuts in aggregate fruit and the width of a nut varies on the higher level (21-29 %). The most variable feature is the mass of a fruit with a high level of variability (33 %). The high flexibility of morphological parameters is noted for the mass of a nut and the amount of nuts in a fruit (0,8-0,9), the average figures of a fruit length and width (0,6-0,7), the low for the length of a nut (0,2)
