Winter hardiness of some Oleaceae species in the collection of the Nikitskiy Botanic Gardens
Abstract
The article characterizes frost resistance of some winter-vegetating species of Oleaceae family in a climate of the Southern Crimean Coast. Olea europaea 'Nikitskaya', Ligustrum lucidum, Jasminum nudiflorum demontrate relatively high frost-hardiness. The realization of potential frost resistance depended both on weather factors associated with the air temperature fall down and on the weather conditions prevailing in the 10-day period preceding the date of frosty weather. High level of real water deficit during the winter period negatively affects the stability of O. europaea cultivars. In the studied species of the genus Ligustrum such correlation has not been revealed.
