Abstrakt/Abstract: The study was carried out in 2011–2014 year at Botanical garden of Slovak University of Agriculture in Nitra, Slovak Republic. For the experiment the following woody plants were taken: Callistemon
laevis Ball., Cupressus sempervirens L., Lagerstroemia indica L., Laurus nobilis L., Nerium oleander L., Pittosporum tobita L., Trachycarpos fortunei (HOOK) H.WENDL., Viburnum tinus L., Vitex agnuscastus
L., Zizypus jujuba L. These woody species were planted in two types of planting, plants planted direct into the soil and stayed outside during winter time and plants planted in pots and protected during
winter time, when plants were removed in to polytunel greenhouse from end of November until end of March. Growth phenology of woody plants refers to seasonal biological life cycles driven by
environmental factors, and is considered to be a sensitive and significant indicator of climate change. The proposed study attempted to quantify changes in selected species. Phenological studies were
carried out during three years, from April 2011 to end of growing season in 2013. Growing phenological characteristics were evaluated and the success of adaptation to the specific environmental conditions
which plants was introduced. Within study period the year increment of individual plants was assessed and compared between two forms of plantings. The pigments and carbohydrate content in
leaves for ever green species were analysed. The sample of young, one year leaves had been taken in end of January when temperature over night was -7 °C. The results showed that there are significant
differences between plants planted outside and plants protected during winter time in all of studied characteristics. Plants planted in ground had the higher chlorophyll a and, chlorophyll b as well
as carotene content in the leaves in comparison with plants in pots which were in greenhouse when temperature has recorded from 4 to 8 °C. On the other hand there was found lower content of starch
and total sugar content in the leaves of plants which were planted in land on open spaces. The differences in studied metabolites content were statistically significant. The study obtained results showed
that the lowest winter hardiness was in Callistemon laevis. The study found that a better hardiness was shown by the deciduous plants. Growth phenophases presented relatively great differences at
the all observed individuals in each year and in both planting types and still greater during all period of observation.
