During three year exploration period it was revealed in laboratory experiment that P. pungens plant pollen from habitats located near large metallurgical combines of Donbass less differs on germination ability and formation of fertilization tube from pollen of plants from the Donetsk Botanical Gardens. Seed productivity of 30 Juniperus excelsa Bieb. trees from natural population of Mauntain Crimea is researched. Most of plants are characterized by high seed emptyness of galberries. Seed productivity of Pinus sylvestris population from Zarechie natural boundary and artifical stands of Kremenets Hills (Ternopol region) is researched and the most perspective plots for creation of the regional fixed forestseed base are chosen. During study of morphological variation of Picea abies seed scales (Ukrainian Carpathians) possibility of coefficients of narrowing and projection using is shown as fenoindices characterising plant cones shape peculiarities. Pinus sylvestris plantations are researched in the north of the Donetsk region and plants resistant to Fomitopsis annosum are chosen. Basic indices of genetic polimorphism are revealed for group of Pinus pallasiana D. Don trees with a rare shape of female cones (Mauntain Crimea). The level of observed heterozygosity (HO=0,175) and expected one (HE = 0,162) was lower as compared to Crimean pine in natural population of the species on 26% and 30% respectively. P. pallasiana and P. sylvestris planting material (120 plants) for planting on coal mine dumps is grown by container method.Four species and 60 samples of drought-resistant conifers plants for growing in rock dump ecotopes are revealed.
