The Christmas rose is becoming a very important ornamental plant on the market. It is relatively new to intensive production technologies. The number of genetically-improved varieties on the market is limited, and many of the old cultivars are no longer available because of slow and economically unfeasible vegetative propagation. In the future, its genetic improvement will probably become inevitable. New cultivars will have to satisfy the specific requirements of the market and producers as well as strict environmental policy. In order to obtain new cultivars it will be necessary to evaluate the exsisting germplasm and apply an adequate genetic breeding approach. There are seven main possibilities of creating new varieties: the use of natural variation associated with seed germination, population approach based on recurrent selection, individual selection based on specific genetic combinations, the creation of inbred lines and the formation of hybrids, interspecific hybridisation, mutagenesis and genetic engineering. Molecular markers can be very helpful during the breeding process. They can be used in order to study genetic relationships amongst populations, ecotypes, varieties, and hybrids. ABSTRACT e placement of a theme park in the form of a Zen garden, as a business opportunity in the Slovenian rural area, is discussed. e design of the garden, with all the major points of a standard business plan, is accurately presented, with a description of the business, branch, and services, market analysis, marketing strategy, nancial projections, and a plan of the work and activities. e nancial aspect is presented as the amount of investment, net present value, and internal rate of return. e amount of investment is estimated at €14.891, which should be reimbursed within 4 years of operations. e estimated internal rate of return is estimated at 16.86%. Part of the study is the market analysis -conduction of a survey into knowledge of, and interest in, Zen and Zen gardens. e principles of landscape ecology are respected, as the Zen garden would be set in the woods and will blend seamlessly into the landscape.
The main objective of this paper was to holistically describe the occurrence of most important crop taxa found in different archaeological Iron Age sites in two selected biogeographical regions of Central Europe; in the Alpine and the Dinaric mountains. This study also links the known results of research about the ecological-biogeographical conditions in the Central Europe during the Iron Age time with the papers that include archaeobotanical data of the selected European landscapes as well. It is evident that many factors played crucial roles in the domestication process of many different plant taxa. This study showed that both the Alpine and the Dinaric region of Europe show similar ecological conditions for successfully growing important legumes and cereal taxa. The percentage of found cereal taxa is higher in the Dinaric region as it is in the Alps. In most archaeological sites in the Dinaric mountains, there were no evidence of the production of pulses at all. However, if comparing the whole repertoire of cultivated plant taxa in the Iron Age epoch in both studied regions, one can conclude that there is not much difference in the number of cultivated planted taxa in the Iron Age epoch.
The scientific monograph covers the botanical classification of the genus Helleborus L. and the Christmas rose species (Helleborus niger L.), which has undergone numerous changes throughout its botanical history. The Christmas rose is becoming increasingly important in the ornamental plant market. Its characteristic flowering in the coldest months of the year represents a great advantage over many other species of ornamental plants. As the Christmas rose does not require high temperatures to start flowering, its cultivation can be considered affordable and environmentally friendly. The supply of attractive varieties is likely to be one of the key factors that will affect its popularity in the future. The number of genetically improved (bred) varieties is limited on the market, so selective breeding of Christmas rose will become inevitable in the future. The presented results of pollination analyses, related to insect activity, are important for breeding. Observations indicate that the Christmas rose is an entomophilous and a predominantly allogamous species. Knowledge of plant ecology and cultivation technology will also be exceptionally important. In intensive cultivation, the production technology for Christmas roses is still to a large extent incomplete. The monograph includes scientific findings on the ecology and biology of the Christmas rose, its reproductive processes, and the production technology for potted plants. The monograph also presents the results of the study on the effects of beneficial microorganisms (bacteria and endomycorrhizal fungi) on the growth and development of seedlings from in vivo and in vitro environments. The results of the study indicate that biotisation is a useful technology and that inoculation with specific microorganisms has a beneficial effect on growth.
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.
