Conservation of biodiversity of especially rare species of peony under ex situ conditions

Abstract

Aim. The results of the introduction study of 4 rare species of paeony (Paeonia anomala L., P. daurica subsp. mlokosewitschii (Lomakin) D. Y. Hong, P. hybrida Pall., P. tenuifolia L.) on the basis of the South-Ural Botanical Garden-Institute of Ufa Federal Research Centre of Russian Academy of Sciences had been discussed in the article. Methods. A study of decorative and economically-biological traits of paeony was conducted in an open ground according to the method of state variety trials of the ornamental plants based on SUBGI UFRS RAS wounds. Seed production of species was calculated according to the generally accepted methodological developments. In the evaluation of resistance to diseases and pests, drought resistance and hardiness were guided by the recommendations of V. N. Bylov and R. A. Karpisonova. The success of the introduction was determined by the scale developed in the Main Botanical Garden RAS. Results. Phenological data, stages of generative development of plants (flowering, presence, regularity and intensity of fruiting) are presented. Morphometric description of the species (plant height, number of vegetative and generative shoots, the length and width of leaf, length of the peduncle, thickness of leaf and flower stalk, diameter of flower, length and width of leaflets, length and width of seeds, etc.) have been presented. Special attention was paid to the study of seed production. The estimation of decorative and economically valuable features of peonies was given. Conclusions. Based on the assessment of the success of the peony species introduction, their prospects for cultivation in the forest-steppe zone of the Bashkir Urals had been shown. Recommendations on the use of rare species in the green building of the Republic of Bashkortostan, as well as their preservation in culture had been given.
