The research was conducted during 2008-2010 in the VÄƒdeni area, Braila County, on four varieties of spring barleyÂ ( Thuringia, Anabell, Cristalia and Tunika ) . The average production of the three crop years was 2362 kg/ha. In 2008, year considered normal in terms of climate, we obtained the highest yields in all four species studied, its value falling between 2350 kg/ha for Cristalia and 3025 kg/ha for Annabell. In terms of year 2009, the production of the studied varieties ranged from 1962 kg/ha for Tunika up to 2250 kg/ha for Annabell, this year being characterized as a dry year. In the third experimental year, 2010, yields ranged from 1937 kg/ha for Cristalia and 2462 kg/ha for Annabell, this year being characterized, in terms of rainfall, as a rainy year, but rainfall was not uniformly distributed. Following the evaluation of the stability of varietiesâ€™ performance using the superiority indexÂ (Pi) , the Annabell variety proved bestÂ ( 28% ) . Research has shown that genetic and climatic factors have influenced the yields obtained from the four varieties studied during three experimental years. In all three experimental years, Annabell variety was superior to all other studied varieties, obtaining productions between 2337 kg/ha and 3025 kg/ha. The production of spring barley in 2008 was significantly superior to other experimental years.","PeriodicalId":9362,"journal":{"name":"Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca.

Considering this fact, in the present study was optimization of the PCR protocol, specially annealing temperature of fifteen SSR primer pairs to characterize and study the genetic similarity and to determine the polymorphism between 36 sweet cherry accessions from I.C.D.P. Iasi, Romania. 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.
