The assessment of stability and productivity of species of the genus Paeonia L. of local and foreign flora

The results of long-term work on creation and studying of the collection of types of Paeonia L are presented by Central Siberian Botanical Garden of the Siberian Branch of the Russian Academy of Science (Novosibirsk) which so far totals 14 views from 3 botanical sections. The purpose of this study was to assess the adaptive potential of species of Paeonia L. genus in the conditions of continental climate of Ob forest-steppe region. All herbaceous species (P. anomala L., P. hybrida Pall., P. lactiflora Pall., P. obovata Maxim., P. oreogeton S. Moore., P. tenuifolia L., P. mlokosewitschii Lomak., P. wittmanniana Hartwiss ex Lindl., P. caucasica Schipcz., P.daurica Anderews) of the genus Paeonia have been safely wintered during 12 years without additional winter protection. When determining the stability and productivity, the highest rating (10 points) was obtained by the species P. lactiflora, P. anomala, P. hybrida, these species exceeded the size of the bushes inherent in them in nature and retained abundant annual seed bearing...
