Assessing the adaptability of conifers and prospects for introduction in the Republic of Moldova

Abstract

Aims. Botanical gardens, nurseries, private gardens, and dendrological collections have a significant fund of Pinophyta species and varieties, many of which grow successfully in the climatic conditions of Moldova. The need to select the most perspective ones for ornamental gardening, and in particular for implementation in green building, prompted a more profound study of their bioecological features and decorative qualities. Methods. During the research, we used commonly used methods and recommendations to update species and varietal composition, determine winter hardiness, drought tolerance, phenological observations, assess reproductive capacity, levels of adaptation, prospects for introduction, etc. Results. Based on a detailed study of the biological and ecological characteristics of the representatives of the Pinophyta division, 107 cultivars can be recommended for use in landscape design in the Republic of Moldova. Almost all the Pinophyta ornamental cultivars studied in different-aged and multifunctional plantations of the Republic of Moldova proved to be quite winter-hardy, drought-resistant, and interesting for landscaping, and therefore deserve wider use in culture. Conclusions. The results of long-term experiments on the introduction of ornamental forms of woody plants of the Pinophyta division in the Republic of Moldova indicate their great potential for enriching the genetic fund suitable for use in landscaping.
