ИСТОРИЯ ФОРМИРОВАНИЯ И АНАЛИТИЧЕСКИЙ ОБЗОР КОЛЛЕКЦИОННЫХ ФОНДОВ ГЛАВНОГО БОТАНИЧЕСКОГО САДА (г. Алматы).

An overview of the dynamics of the quantitative composition of the Main Botanical Garden's (MBG) living collections from the time it was formed to the present day is given. The distribution of taxa by expositions and collection sites, their systematic affiliation, peculiarities of the formation of collections in different periods of the existence of MBG, and features of ontogeny in different groups of taxons are discussed. The combined living collection fund of the MBG includes 3225 taxa of higher plants in 150 families, 667 genera, 1853 species, 343 forms, and 1076 plant varieties representing domestic and worldwide flora from different regions of the globe. The most represented families are Asteraceae, Lamiaceae, Rosaceae, and Fabaceae however, most families (78) are represented by only 1-2 species. The genera Allium and Crataegus (by 43 species each), Iris (36), Pinus (23), Acer (21), and Betula (20) are distinguished by the number of species. By varietal diversity the most representatives are Rosa - 175 varieties, Syringa vulgaris - 126 varieties, Hemerocallis hybrida - 102 varieties, irises (82 varieties), Narcissus hybrida (72 varieties). The varietal collections Tulipa hybrida (41 varieties) and Hosta hybrida (38) are also representative. The vital state of most plants is quite satisfactory; under our conditions, about half of the collection plants pass the full ontogenetic development cycle and produce completely viable seeds. Another 30% of the collection plants are highly active in flowering but breed only vegetative. [ABSTRACT FROM AUTHOR]
