Obserwacje fenologiczne wybranych gatunkow drzew i krzewow z rodziny Celastraceae i Rosaceae introdukowanych w Ogrodzie Dendrologicznym Akademii Rolniczej w Poznaniu

Systematic, phenological observations over selected deciduous species of trees and shrubs have been carried out in the Dendrological Garden from 1995. Estimation of their development is based on the climatic factors and on the indicator plants for the individual phenological seasons. Observed species of the Celastraceae and Rosaceae families, derived from Eastern Asia are well adopted to our phenological seasons. Resistance to low temperature and drought, creation of natural renewal and full life-cycle during the vegetation confirm their adaptation to the climatic and site conditions of the Dendrological Garden.
