Journal Title: Біоресурси і природокористування [Biological Resources and Nature Management] - Year 2018, Vol 10, Issue 5
Abstract
Rodgersia aesculifolia Batalin of Saxifragaceae family characterized with ecological plasticity and high decorative quality and this plant is prospective for Kiev landscaping. There were not carried out scientifically based studies to determine the winter resistance of plants R. аesculifolia in terms of Kiev, because the plant is little known to a wide range of domestic researchers. The purpose of the research is determination of the R. аesculifolia winter resistance under the conditions of introduction and obtaining scientifically grounded data about the plant cultivation features in terms of open soil of Kiev. According to the results of comparative assessment of the R. аesculifolia plants state in terms of fluctuations in the temperature regime during the autumn-winter period it is concluded that there are sufficiently favorable conditions for their successful wintering. Analysis of R. аesculifolia plants rhizomes freezing allow to revealed: insignificant damages for –5,0 and –8,0 °C temperature (16 and 22 points); at – 10,0 °C – the 40 % damage reached level of the total tissue volume (43 points); at – 12,0 and –14,0 °C – severe damage (57 and 62 points), at –16.0 °C – found complete tissue death (98 points).
