Cultivation of Crimean Flora Species in the Conditions of the Main Botanical Garden of Moscow: Historical and Modern Aspects

Abstract

The results of conservation of the gene pool of the Crimean flora in the Main Botanical Garden (MBG) since 1945 are analyzed. About 240 taxa have been identified, of which about half are promising for ex situ conservation. The experience of creating a new collection of Crimean flora is presented, for which the results of the introduction of 9 taxa for more than 5 years and the features of seed germination of 4 taxa in laboratory conditions were studied. A low percentage of germination of seed samples collected in natural conditions is shown: Stipa capillata, Scabiosa argentea, Xeranthemum annum. The germination of seeds of the potentially invasive species Spartium junceum was studied with four variants of pre-sowing treatment: soaking, scalding, scarification and no treatment. The conducted studies have shown that the best indicators of seed germination of Spartium junceum after pre-sowing treatment in the form of scalding. Taxa promising for further conservation under the conditions of the MBG have been identified.
