Linear growth of lateral shoots of the introduced plants of the species Crataegus L. at the Polar – Alpine Botanical Garden and Institute

Abstract

The work is devoted to the study of lateral shoots' seasonal growth of introduced species of Crataegus L. in the Kola Peninsula conditions (as exemplified by the city of Apatity). The alternation of the periods of intensive and weakened growth caused by weather conditions is typical for seasonal dynamics of growth of lateral shoots of the samples Crataegus L. introduced in the central part of the Kola Peninsula. The culmination of the linear growth of shoots occurs with an increase in average daily values of temperature and relative humidity of air. Species affiliation affects the duration of linear growth of lateral shoots of introduced Crataegus species.
