The strategies of fight against soft rot disease also takes into consideration the possibility of using unconventional, environmentally friendly products, as extracts of garlic (Allium sativum L.), or even selenium enriched garlic as control agents for Erwinia carotovora. The aim of this study is to emphasize the effects of different concentrations of aqueous garlic and organic selenium enriched garlic (Allium sativum L.) extracts upon Erwinia carotovora bacteria isolated from potato. Aqueous extracts were prepared from fresh bulbs of Allium sativum L. and organic selenium enriched Allium sativum L. as 100% concentration, and aliquote parts were isolated in order to prepare 10%, and 20%, dilutions were prepared. The disc diffusion method was chosen for determining antibacterial activity of aqueous garlic extracts. The STATISTICA 7.0 v. soft was used for basic statistics, and testing the significance of differences between experimental variants. The 20% aqueous solution produces a diameter of inhibition was in average of 12.28 mm and 10% aqueous garlic an average diameter of 11.95 mm. The differences were statistically not significant. The most important performances were recorded for 20% aqueous solution of selenium enriched garlic that emphasized the highest activity against Erwinia carotovora (87.71% zone of inhibition).","PeriodicalId":9362,"journal":{"name":"Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca.

In the optimization process of annealing temperature for primers, was started with 5oC less them the temperature recommendated by the manufacturer, gradually ascending with 1-2oC/PCR cycle, up to 10-11oC, above the recommended value. For every primers pairs it was 6-7 steps for optimization of annealing temperature, obtaining satisfactory results to the following primers pairs: UCDCH17, UDP96-001 and PceGA25 at 65oC, UCDCH21: 64oC, UCDCH31: 66oC,:UPD97-402: 60oC, PMS3: 68oC. The primer pairs UDP96-008 obtained at 65oC, monomorphic bands, so it was excluded from the analysis. The other reagents used in PCR and temperature regimes (denaturation and extension temperature) were kept constant. From these results we conclude the transferability and applicability of SSR markers for genotyping and phylogenetic studies in the genus Prunus.","PeriodicalId":9362,"journal":{"name":"Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca.

The main advantage of these populations is that the heterosis does not diminish significantly in F2. In order to complete the research on the combining ability of maize synthetic populations, the objective of this work was to study seven maize synthetic populations, determining their general combining ability (GCA) and specific combining ability (SCA) for kernel starch content, as well as their potential as source populations in breeding programmes.To achieve the proposed objectives, we studied top cross hybrids of the type â€œinbred line x synthetic populationâ€ resulted from the crossing between seven synthetic maize populations and four early inbred lines used as tester. For all experimental conditions, the differences between genotypes were statistically assured for kernel starch content. The experimental years and testing locations have provided conditions for differentiation of genotypes for starch content and interactions between the environment and genotypes were statistically significant, indicating dependence of starch content on environmental conditions. The additive effects for starch content provided by GCA were high for Tu SRR 5DR(6I)(5) and Tu SRR 5D (2I)(2). Non additive effects, corresponding to SCA were high for the following hybrid combinations: TC 233 x TuSyn 1 (3), CO 255 x Tu SRR 5D (2I)(2) and TC 209 x Tu SRR 5DR(6I)(5). In the case of synthetic maize populations, the determinism of starch is influenced equally by GCA and SCA.","PeriodicalId":9362,"journal":{"name":"Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca.

It is known that beach young trees have poor resistance to extremes of climatic variations. The aim of our research is to identify the main particularities of the seedlings behavior within accidental low temperature determined by changes occurred in climatic conditions. Observations were performed, during a three years period, 1996 - 1998, from April to the end of May, in 4 units located on the plateau areas of Sovata Forestry Office, in order to record negative temperatures that could affect the seedlings regeneration. The lowest temperatures were 1.1 0C during the night of 22/23 May and 3.0 0C during the night of 23/24 May, 1998. In all four analyzed units located in the vicinity of the mountaintop, beech seedlings were less affected by the late frost. Until fall 1998, a rate of 10 - 12% of affected seedlings was dry, the rest having changes more or less accentuated. As a result of late frost reported in the end of May 1998, 10 - 20% of seedlings were injured.","PeriodicalId":9362,"journal":{"name":"Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca.
