Phytophthora Drechsleri

The pathogenicity of 35 isolates of Phytophthova dvechsleri obtained from native forest and other sources throughout Australia was examined, with Carthamus sp., Helianthus sp. and Citrullus sp. as the test hosts. Fourteen southern and 20 northern ecotypes of the fungus were pathogenic to Carthamus but not to Helianthus or Citrullus; a single isolate of the A1 mating strain was non-pathogenic to all three hosts. The relevance of these findings to agriculture and forestry is discussed.

Despite more than a century of research on effective biotechnological methods to reproduce various plant species, microclonal reproduction continues to be an important tool for large-scale production. The clonal seedlings of important species maintain genetic fidelity and do not contain pests. In some cases, microclonal propagation is the only method that contributes to the maintenance and economic value of specific agricultural plant species. Microclonal reproduction as a method has solved many phytosanitary problems and has allowed both expansion and access to high-quality plants for producers from different countries and economic conditions, thus effectively contributing to the expansion of agriculture now and in the foreseeable future. Currently, this method is widely used in the creation of planting material for crops for agriculture and cultivation of crops of industrial floriculture, fruit, berry crops and woody plants. Thanks to this method, it is possible to create in vitro banks of rare and valuable plant genotypes. Modern technologies of clonal micro-multiplication are at the stage of industrial flow, which quickly responds to market demands. The analysis of domestic and foreign sources of scientific research on microclonal plant propagation has shown that, at the present time, the cost of its use is quite high and requires the presence of laboratories with appropriate equipment and highly qualified staff. Modification and adaptation of the method of microclonal reproduction of plants contributes to the implementation of the morphogenetic potential, determines the specific features of the source material, the type of explant, its physiological state, the composition of nutrient media, and cultivation conditions. At the same time, the cultivation of healthy plants will significantly increase the yield of valuable agricultural products and high adaptive properties of healthy plants that allow them to be cultivated with less chemicals, which will significantly increase their nutritional value and give a greater opportunity to obtain organic products with high-quality characteristics.

The occurence of atmospherical drought causes serious water-supply problems in the most cases of our domestic agricultural plant species. This paper was studied, how can we quantificate the atmospherical drought, with the help of a low input (relative humidityof the air, temperature) index. If this index (LSZI) characterized the atmospherical drought well, it will suitable to estimate the yield amount of agricultural plants.The index elaborated by the authors was tested on county average crop yield of 14 agricultural plant species. Moreover we compared the atmospherical drought index (LSZI) to other aridity parameters, how suitable for estimate the yield amount.Result of experiments show that, the atmospherical drought index (LSZI) can be used well by several agricultural plant species in especially coern and sugar-beet to estimate yield amount. Excellent results were found by comparison to other aridity indexes, this means it is worth using in the aridity researches in the future.

Analysis Techniques

The main issue discussed in the paper is the application of qualitative analysis techniques when short data samples are available at the initial stage of experiments carried out to study behaviors of agricultural plant species under different environmental conditions. The proposed techniques are described on the examples of two tasks: analyze behaviors of chemical elements in plant species irrigated with treated wastewater (on the example of Brocoli cabbage), as well as in plant species cultivated near the highway (on the example of Lycopersicum species). The system of ecological interactions is decomposed into individual subsystems with sufficiently small number of variables describing concentrations of elements. The Group Method of Data Handling (GMDH) is applied to obtain the regressions between variables within subsystems. The Qualitative Description based on signs combinations of differences for a regression function is employed to qualitatively analyze the relationships among variables, both within individual subsystems and within the system in whole. This approach makes it possible to identify main behavior features of individual objects/relationships between objects, classify behaviors according to different criteria of similarity/distinction, provide feature matching, etc. The obtained results then can be used to design the next-stage experiments and construct more comprehensive models of plant species behaviors.

The conservation of plant genetic diversity underpins the future of agriculture, food and nutrition security and is critical to ensure the ability of future generations to cope with global environmental changes. The conservation efforts were more focused on orthodox crop species in Nepal before 2010. About 40% of agricultural plant genetic resources are non-orthodox, either recalcitrant/ intermediate type or vegetatively propagated plant species. Approaches for conservation of non-orthodox plant species differ from that of orthodox crops. Different conservation approaches have been established by National Agriculture Genetic Resources Center, Nepal for conserving non-orthodox agricultural plant species. We applied household survey, literatures survey, field survey, key informant survey and organized focus group discussion for assessing the different conservation approaches. A total of 24 approaches are being considered for conservation of non-orthodox plant species. Approaches under the ex-situ strategy are field genebank, botanical garden, city park, government farm, religious place, in-vitro culture and evolutionary plant breeding; under on-farm strategy are community field genebank, school field genebank, household field genebank, community/ public orchard, village level field genebank, geographical indication and participatory landrace enhancement, and under in-situ strategy are protected area, Ramsar site, world heritage site, community forest and legal protection for conserving non-orthodox plant species in Nepal. Field genebank is the very good approach, and it has been established in about 20 research stations. It should be extended to government farms and agriculture offices to conserve the local APGRs available in their respective command areas. Databases (passport and characterization) have been generated and will be available online to enhance the utilization in breeding, research and production.
