The cultivated dondroflora represents a complex of trees, bushes and lianas of autochthonous and allochthonous origin, which accommodates at pedo-climatic conditions and are used in different proportions in practice. Apparition and establishing of the cultivated dendroflora is the result of multiannual process of introduction, which registered ascensions as well as descensions. The valorous period of plant introduction is registered in the second half of the last century when the Botanical Garden of the Academy of Science of Moldova was created. In that period the introduction process gets a scientific connotation and in the short period of time 2000 species, forms and varieties of trees, bushes and lianas were introduced and experimented. At present, a great genetic fund of woody plants is accumulated in green spaces and dendrological collection which counts about 808 species and 625 forms and varieties (total about 1500 taxa) and belong to 67 families and 199 genus. The Pinophyta division is represented by 7 families, 26 genus and about 375 species and varieties. Two families - Pinaceae and Cupresaceae are the most representative counting about 95% of the total taxa from this division. The majority of 70% of taxa are trees, but the bushes represent the rest of 30%. The lianas, as a vital form, are missing. Only 60 taxa (16%) from this reach genetic fund are used in practice (frequency "permanent" and "everywhere"). Magnoliophyta division is represented by 1125 taxa from 60 families and 173 genus, of which the most representative are ten families or 74% of the total taxa of this division: Aceraceae, Berberidaceae, Betulaceae, Caprifoliaceae, Fabaceae, Fagaceae, Hydrangeaceae, Oleaceae, Rosaceae, Salicaceae. The most common vital form are bushes, about 53% of the total number of taxa, trees 40% and lianas 7%. Only 315 taxa (28%) from this reach genetic fund are used in practice (frequency "permanent" and "everywhere"). Absence of seed production system and modern technology on reproduction and breeding, as well as deficiency in economic  evaluation and marketing for each taxa are the reasons of an insufficient usage of genetic fund of introduced dendroflora.
