DownloadTHE STUDY OF VEGETABLE EXTRACT ACTION OF LOLIUM PERENNE L. ON SOME PERENNIAL GRAMINAES CHEMICAL COMPOSITION pag. 9-14
Cristian Bostan, Alexandru MoisucThe purpose of the researches is represented of determination of allopathic effect realized of Lolium perenne L. on perennial graminaes Festuca rubra L., Dactylis glomerata L. and Poa pratensis L. In the vegetal preparation of Lolium perenne L. have been found compounds with allopathic character which corresponds to some other researches realized on global level. The studied biologic material is represented of four perennial graminaes species: Dactylis glomerata L., Lolium perenne L., Poa pratensis L. and Festuca rubra L., studied in laboratory conditions and in vegetation pots. The experience have been established in three repetitions. Excepting the witness that have been watered only with running water, the other vegetation pots have been splashed with deafly alcoholic pirolizidinici alkaloids white extract, respectively ergotic obtained from the aerial vegetal part of Lolium perenne L. specie. The estract have been applied in three different shots, shot of 10 ml/pot, 40 ml/pot and 80 ml/pot. The novelty degree of the paper and personal contribution results from the fact that on national level, perennial graminaes that have been studied have not been completely characterized from allopathic point of view. Between the factors that threaten the biodiversity and to which must get the profile research are allelochemical compounds. Their structure and their way of action are different and can built start points for realizing new herbicides. The paper importance results from the fact that through these experiments, have been proved the alkaloids influence (on changing the quality parameter of plants that have been studied) did reflected through an a small decrease on crude protein contain.

DownloadEVOLUTION OF THE PEST DIABROTICA VIRGIFERA VIRGIFERA LE CONTE IN THE SOME LOCALITIES FROM ROMANIA pag. 36-42
Octavian Crişan, Ioana Grozea, Ramona ŞtefDiabrotica virgifera virgifera Le Conte called western corn rootworm was signaled for the first time in our country, in 1996, in the Arad District (Nădlac). In 1997 it was detected in the Timis District too, which neighbors with the Arad District and with Yugoslavia and Hungary. This scientifically papers present the results concerning the pest's evolution in some localities (Simand -140 m, Soimi -145 m, Blaja-150m, Nusfalau –214 m, Prisaca -270 m Negreni- 388 m and Budureasa –403 m) from western part of country (South-West–North of Romania), in 2009. Selection of these locations was based on altitude, from plain until mountain. For monitoring of the adults were used hungarian pheromone traps (Csalomon ® Diabrotica v.v. tip panou/2). The traps were installed from June to September. The frequency of Diabrotica virgifera virgifera Le Conte adults was manifold, based on location and ecological conditions. The highest number of adults was registered to Simand locality (21323 captures), that is placed in a low altitude, by140 m. The lowest number of adults was captured to beginning of 403 m altitude (2156 captures), in Budureasa locality. It’s important to point that number of captures decreased while the altitude increased. It results that Diabrotica virgifera virgifera Le Conte is a large disseminated pest in the western part of country and in consequence his control will be necessary. The results were obtained by financially and material support of PN-II-ID-PCE-2007-1/RO (889) project.

DownloadHOST GENETIC FACTOR’S INFLUENCE ON THE PESTS OSTRINIA NUBILALIS – FUSARIUM ROSEUM – UNDER CONDITIONS OF GENETICALLY-DIFFERENT TROPHIC BASE pag. 76-81
Dorin Jurca, Gheorghe PopescuSince any resistance to the parasitical attack (Ostrinia nubilalis – European maize gimlet and Fusarium roseum – stalk rot or fusariosis) has not been induced so far, excepting the genetic engineering preoccupations, which managed to do this in the transgenic way, we considered it was necessary to experiment a genetically-different trophic base, represented by conventional and transgenic maize hybrids, attempting to constitute new resistance sources in the first case or to ameliorate the sensibility in the conventional maize hybrids cultivated at the moment. Successive to our results regarding the genetic reaction of the hybrids studied, in Arad County, we may conclude the following: Under conditions of comparative crop, in the refuge area system, the tolerance gets lost, proving that under normal experimental conditions the tolerance is not total, but relative; under such conditions, the genetic response is of sensibility; The type of the conventional maize genetic response is of sensibility to fusariosis at cob level ; The type of the Yield-gard maize genetic response is of transgenic resistance to fusariosis at cob level, and not of euresistance or genetic resistance.

Three wheat variety seeds (durumko, renesansa and pobeda) were disinfected with electron plasma and treated just before sowing with low frequency electromagnetic field (from 0-100 hz). For seed disinfection we also used pesticides, for comparing and we sowed seeds without disinfection (control for all treatments). Electron treatment didn’t have significant effect on yield in compare to chemical disinfection treatment; the difference was 30kgha -1 . However, justification of this treatment is more important from ecological viewpoint. Treatment with extremely low frequency electro-magnetic field, increased wheat yield for270 kgha -1 in compare to untreated seed.

DownloadCONSIDERATION ABOUT THE COSTS OF ORTHOPHOTOPLANS IN ROMANIA pag. 102-110
Laurentiu Pana, Mihaela SpilcaToday, many uses for geospatial mapping products require current planimetric feature data. Analysis and design from geospatial data sets generally require a known positional accuracy of features. The collection and updating of planimetric features in a data set can be costly. Many end users are also not accustomed to viewing and analyzing vector-based mapping data sets. They prefer to view planimetric features as a photo image. An orthophoto map would show the arch as an easily identifiable unique image feature. The cost to collect and update planimetric features can be significant. Costs can sometimes be minimized by the production of a photo-based digital map set that is spatially accurate throughout. Many GIS data sets make use of photo-based image data for these purposes. The Internet offers orthophotograph tutorials which may aid managers interested in the basic study of the subject.
