Abstract

Background. One of the main functions of botanical gardens is the study of introduced plants in order to increase the diversity of commercially valuable species. The purpose of this work is to investigate the biology of tree and shrub species of the family Rosaceae Juss in conditions of the Sprygin Penza botanical garden in connection with the prospects of their application.
Results. The Penza botanical garden’s collection contains 106 taxa of trees and shrubs of the family Rosaceae belonging to 4 subfamilies: Spiraeoideae, Rosoideae, Maloideae, Prunoideae. A list of taxa is presented in the article. Ecological and biological characteristics of Rosaceae plants in the Sprygin Penza botanical garden are investigated. The degree of adaptation of alien species is estimated.
Conclusions. Based on the observations of 83 species of the family Rosaceae, introduced in the Sprygin Penza botanical garden, most of the taxa can be used for broad introduction to the culture as fruit, decorative, honey, and medicinal plants: Amelanchier alnifolia, Crataegus submollis, Cotoneaster lucidus, Malus baccata, Malus prunifolia, Padus virginiana, Pentaphylloides fruticosa, Pyrus elaeagnifolia, Rosa rugosa, Rubacer odoratum, Sorbaria sorbifolia, Spiraea japonica, S. media and others. Few taxa are considered as limited to introduction: Kerria japonica var. pleniflora, Cerasus tomentosa, Crataegus nigra, Rosa x kamtschatica, Rubus illecebrosus, Spiraea x bumalda “Crispa”.
