National plant genetic resources of ornamental plants and morphological characterization of Paeonia.

摘要

In 2001, the Seimas (Parliament) of the Republic of Lithuania adopted the Law on National Genetic Resources of Plants. According to the provisions of this law, the genetic resources of plants, which have ecological, selective and economic value for the Republic of Lithuania, are selected and included into the central database of national genetic resources of plants. Currently, 8 institutions are involved in activities of collection, investigation and conservation of plant genetic resources. Plant Gene Bank with Coordination Centres of different plant groups (agricultural plant, forest trees, fruit and vegetables, medical plants and ornamental plants) was established and operates until now. A group of ornamental plant cultivars were included in the National List of Plant Genetic Resources: 48 cultivars of Paeonia, 4 cultivars of Primula, 40 cultivars of Iris, 15 cultivars of Gladiolus, 8 cultivars of Dahlia and 5 accessions of wild flora ( Helianthemum nummularium, Tulipa bifloriformis, Trolius europaeus, Salvia officinalis f. rubicunda and Lathyrus maritimus). When a plant is granted the status of national plant genetic resources by the Order of the Minister of the Environment of the Republic of Lithuania, the documents in the set form meeting the BI ( Bioversity International) requirements are prepared. One of the aforementioned documents is a characterization descriptor. The described plant determines the content and the scope of its descriptor. This paper discusses the descriptor of morphological and decorative traits of peonies ( Paeonia L.).
