Abstract

The results of introduction studies of 15 Caucasian species of the genus Primula L. (Primula abchasica, P. acaulis, P. algida, P. amoena, P. cordifolia, P. darialica, P. farinosa, P. juliae, P. komarovii, P. macrocalyx, P. pallasii, P. ruprechtii., P. saguramica, P. sibthorpii, P. woronowii) conducted in the Polar-Alpine Botanical Garden and Institute are presented. Currently, the institute’s collection contains 8 species (P. acaulis, P. amoena, P. juliae, P. macrocalyx, P. pallasii, P. ruprechtii, P. saguramica, P. woronowii). Ecological and geographical analysis has shown that the species best adapted to the conditions of the Arctic are those that live in the alpine (P. algida, P. amoena, P. cordifolia, P. juliae, P. pallasii, P. ruprechtii, P. sibthorpii – introduction coefficient [IC] =9.4) and subalpine zones of mountains (P. macrocalyx, P. acaulis – IC=8.2). While plants found in the broad-leaved forest zone are less adapted to the new living conditions (P. komarovii, P. saguramica, P. woronowii -IC=6.4). The current research establishes that species of the genus Primula can serve as a source of plant assortments to replenish landscaping in cities in the Murmansk region. For this purpose two new decorative and sustainable species (P. macrocalyx h P. ruprechti) are recommended.

Since 1934, the PolarAlpine Botanical Garden and Institute (PABGI) has been studying the effects of introducing species of the genus Primula, with 121 species of various ecological and geographical origins added to the collection nurseries
Ecological and geographical analysis showed that the species best adapted to the conditions of the Arctic are those living in the alpine (P. algida, P. amoena, P. cordifolia, P. juliae, P. pallasii, P. ruprechtii, P. sibthorpii – introduction coefficient (IC)=9.4) and the subalpine belt of mountains (P. macrocalyx, P. acaulis – IC=8.2)

Introduction

Ecological and geographical analysis has shown that the species best adapted to the conditions of the Arctic are those that live in the alpine (P. algida, P. amoena, P. cordifolia, P. juliae, P. pallasii, P. ruprechtii, P. sibthorpii – introduction coefficient [IC] =9.4) and subalpine zones of mountains (P. macrocalyx, P. acaulis – IC=8.2). The current research establishes that species of the genus Primula can serve as a source of plant assortments to replenish landscaping in cities in the Murmansk region. For this purpose two new decorative and sustainable species (P. macrocalyx и P. ruprechti) are recommended. The aim of this work is to analyze the introduction tests of Caucasian species of this genus to determine their viability in being introduced in the landscaping assortment for cities in the Kola region
