This section analyses the state of disturbed lands as a result of the illegal extraction of amber in the Rivne region. The general characteristics of the territories and the negative consequences of illegal amber production are given. Were analysed and found possible future composition of vegetation of specific Dubrovytsky forestry area. The main stages and directions of reclamation of disturbed lands are considered. As a result of the analysis of literary sources and archival data, possible options for reclamation on the disturbed lands were suggested. It has been established that conducting a complete reclamation of sites damaged by illegal amber production is the only technically available method, given the nature and extent of the violation of these lands. It has also been found that the pilot-industrial extraction with 100% the extraction of the remaining amber is a prerequisite for preventing the repeated illegal intervention of the diggers on the reclaimed land. It is established that after the completion of the pilot-industrial extraction and technical reclamation it is necessary to conduct additional ecological and economic assessment of the disturbed territories in order to further extract amber, forestry and use for agricultural production
The authors present the results of the collection’s formation of some ornamental shrubs, long-term phenological observations of them and the selection of the best forms and breeding hybrids in the Left-Bank Lisosteppe of Ukraine. In particular, the characteristic of the vegetation of 20 varieties of common lilac collection is given. The estimation of the terms and duration of the crop flowering enable to divide its varieties into groups of early, average and late flowering. The high decorative value of most of the strains has been described as well as their resistance to low temperatures and pests. The additional analysis of the latest literature data has shown the significant yield of aromatic substances in the common lilac plant, with the predominance of alkanes and lilac alcohol. The results have been presented of 70 rose cultivars of adaptation to the growing zone conditions. There are 20 promise varieties of the crop, which are characterized by high decorative value, resistance to pathogens and low temperatures and duration of flowering. The characteristics of the new variety of roses of the floribunda group – Olexandra has been given created by the authors. Along side with the high decorative value, different types of the rose plant provide the significant yield of aromatic substances with the domination of alkanes, monoterpenes and 2-phenylethanol. The analysis of the literature data also has shown the presence of aromatic substances in the jasmine and mock-orange plants. The first is characterized with esters based on benzene, cis-jasmon and isophytol, the second – with some sesquiterpenes and epi-13-manol. The further research included the phenological evaluation of the of white cedar and juniper collection. The best selected forms were characterized with decorativeness, resistance to frost, pests and pathogens. The literature data have shown, that the aromatic complex of the crops cultures includes mainly monoterpenes and their derivatives – alcohols and ketones. As a result, it was concluded that it is necessary to expand research with ornamental bushy crops in the direction of evaluating of their aromatic properties.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
