Abstract
Root-knot nematodes Meloidogyne spp. are obligatory pests of several mono- and dicotyledons. They are able to induce swellings (root galls) on the host roots on which they develop and propagate. Meloidogyne spp. belong to the economically important harmful organisms. The extent of harm caused depends on the host type and the root-knot nematode species. More than eighty nominal species have been described worldwide while 21 species have been detected in Europe so far. Until now only four species: M. hapla, M. incognita, M. arenaria in M. ethiopica have been detected in Slovenia. According to possible economic influence of M. ethiopica, lack of information about its spreading and especially lack of information concerning its influence on the quality and quantity of crop production in Slovenia, we intend to study this group of plant parasites more intensively. We will focus in particular on the species M. ethiopica which was first described in Africa and for the first time encountered in Slovenia in 2003. This was also its first find in Europe. In this research project the presence of individual species of this genus and geographic spread of individual species in Slovenia will be studied more systematically. In the frame of the study of M. ethiopica we will try to determine the host plants which can be parasitised by M. ethiopica using the pot-experiments. We will focus on the host plants typical for the Primorska region of Slovenia. The capability of surviving of M. ethiopica in the Slovene climate conditions and the length of one whole generation of M. ethiopica with regard to various temperatures will be determined. Various scenarios of climate changes occurring in Slovenia will be analysed, their influence on development abilities of the species M. ethiopica will be studied and an analysis of risk of settlement and spreading of this species in Slovenia will be made. We will study the genetic variability of individual populations of M. ethiopica and define the presence of virulent and avirulent genes in M. ethiopica. We will also define the virulence of M. ethiopica according to the presence of Mi resistance gene in the most frequently used Slovene cultivars of tomato plants.
Significance for science
The programme was based on application of SCF for sustainable processes with minimum environmental impact and for producing innovative bioproducts with specific properties and high added value. The trend of replacing synthetic compounds with natural active components is directing the research onto new plant resources and identification of new compounds with antioxidative or antimicrobial activities. The development of new products based on natural materials with biological activity, in a suitable form and a desired stability and low price, requires enormous research of new methods for product formulation. The final results of the projects have contributed to identification of new plant materials and their residues as a source of various biologically active compounds. Cleaner and more sustainable methods for their formulation have additionally been presented. The results have also contributed to new knowledge on applying different polymers for attachment of biollogicaly active compounds isolated from plant materials and their further use. Knowledge in the field of chemistry, pharmacy, biochemistry, health science and technologies has been merged and transferred into industrial environment.
Significance for the country
The application of SCF in industry is increasingly becoming interesting for the new Europena directive is based on reducing the consumption of organic solvents. The development of new product technologies with SCF ha numerous advantages over conventional separation processes. The new technology enables higher productivity, product stability and homogenity. The research has contributed towards: - Two-way flow and use of knowledge for economy development and stimulation of competitiveness; closer cooperation between scientific and economic spheres, faster flow of knowledge into products and processes with high added value. Through transfer of knowledge via scientific and expert achievements the research project has increased the influence of R&D in domestic environment and contributed to increase of quality of R&D, which is the basis for increasing sustainable economy growth in Slovenia. - Connecting measures for achieving sustainable development with emphasis of horizontal guidelines for sustainable development and transition to low carbon community and international enforcement of slovenian knowledge in the field of application of SCF for efficient isolation, separation and formulation of biologically ative compounds from plant materials.
