Erwinia carotovora is an important threat for potato cultures, producing the soft rot disease. 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).
胡萝卜Erwinia carotovora是马铃薯栽培的重要威胁,产生软腐病。防治软腐病的策略还考虑到使用非常规、环保产品的可能性,如大蒜提取物(Allium sativum L.),甚至富含硒的大蒜作为胡萝卜Erwinia carotovora的防治剂。本研究的目的是研究不同浓度大蒜和有机硒大蒜(Allium sativum L.)提取物对马铃薯胡萝卜欧文菌(Erwinia carotovora)的影响。以新鲜大蒜鳞茎和有机富硒大蒜鳞茎为原料,分别以100%的浓度制备水浸提液,分离aliquote部分,分别配制10%和20%的稀释液。采用圆盘扩散法测定大蒜水提物的抑菌活性。采用STATISTICA 7.0 v. soft软件进行基础统计,并检验实验变量间差异的显著性。20%水溶液对大蒜的抑制直径平均为12.28 mm, 10%水溶液对大蒜的抑制直径平均为11.95 mm。差异无统计学意义。20%富硒大蒜水溶液对胡萝卜欧文菌(Erwinia carotovora)的抑制率最高,达到87.71%。

The paper intends to present the soil quality effect (CWS), given by the National Institute of Soil Science official creditworthiness marks on the Burnas Plain wheat yield. In this way is created the scientific basis for new technologies (varieties) that are about to provide a better exploitation of the soil and of its characteristics, as well as the influence of biotic and abiotic factors (water, heat) from Burnas Plain, a significant wheat growing area. There has been found a positive correlation between soil quality and yield. It was also observed that increasing technologies are reducing the differences of production in order to equalize between yields on poorer soils compared to the richest. Therefore, the soil working technologies solves numerous defects of poor or degraded soils. For this, the working capital is decisive and so is the agricultural science well applied.

Red deer ( Cervus elaphus L. ) populations, depending on their density can dramatically affect vegetation in their living areas using hay meadows, farmland tree plantation and orchards, leading to a financial deficit for the farmers. We quantified grazing intake in natural vegetation fields that were bordered by forest and had been used as hay meadows. Grazing cages had been placed in three separate locations in Valea Mare hunting range from Bistriţa-Năsăud during 30 May - 15 July period. Sampling took place shortly before the hay meadows were mowed with the purpose of quantifying the Red deer intake. Red deer grazing resulted in the loss of a percentage between 11,6% and 12,6% of the total production.

For introduction of this material (accessions) into the breeding programs is necessary and important to know the level of characterization. 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.

Phytosanitary treatments and quality of weed control depends on the amount of the used liquids, the uniformity of the distribution per area, the coverage and penetration of the vegetal mass, the flow rate of the liquid and the size of the formed droplets. Most of these parameters are accomplished by nozzles. Nozzles are the most important parts of the spraying machines. They turn the herbicide mixture in small drops that are thrown towards the target surface. This jet drops contains particles of different sizes. Nozzles are components that turn the under pressure liquid column into a spray of drops, called jet.

Synthetic populations of maize (Zea mays L) are low-cost and stable varieties, obtained by cross pollination of a group of inbred lines, local population or hybrids. 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 “inbred line x synthetic population†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.
玉米合成群体(Zea mays L)是由一组自交系、当地群体或杂交种杂交获得的低成本和稳定的品种。这些群体的主要优势是杂种优势在F2期没有明显减弱。为了完成玉米合成群体配合力的研究,本研究对7个玉米合成群体进行了研究,确定了其籽粒淀粉含量的一般配合力(GCA)和特定配合力(SCA),以及它们作为育种源群体的潜力。为了实现上述目标,我们研究了7个玉米合成群体与4个早期自交系杂交得到的型€œinbred系x合成群体的顶级杂交杂交种。在所有试验条件下,籽粒淀粉含量的差异在统计学上得到了保证。实验年份和测试地点为淀粉含量的基因型分化提供了条件,环境与基因型之间的相互作用具有统计学意义,表明淀粉含量对环境条件的依赖性。GCA对Tu SRR 5DR(6I)(5)和Tu SRR 5D (2I)(2)淀粉含量的添加作用较高。tc233 × TuSyn 1(3)、co255 × Tu SRR 5D (2I)(2)和tc209 × Tu SRR 5DR(6I)(5)的非加性效应与SCA相对应。在合成玉米群体中,淀粉的确定性同样受到GCA和SCA的影响。

Within new established tree nurseries, for development of young trees in the early years, the determining factor is their ability to resist deviations from normal climatic elements. 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.
