Here, seven different starter cultures used in the production of fermented sausages were screened for the presence or absence of specific DNA sequences coding for tyrosine decarboxylase. PCR with the a set of specific primers TDC2/TDC5 (COTON et al., 2004) was used. The PCR analysis of DNA from two starter cultures confirmed the presence of DNA sequences for tyrosine decarboxylase. A detailed analysis of the starter cultures showed that DNA sequences for tyrosine decarboxylase are contained in genomic DNA of Lactobacillus curvatus and Lactobacillus sakei.These results show suitability of the described PCR method for the screening...

Woody and herbal growth growing on banks and along watercourses are called vegetative accompaniment of watercourses. In the Czech Republic, there has not been a unified methodology for the assessment of vegetative accompaniment of watercourses. Main objective of the work was to desing a simple methodology for the assessment of vegetative accompaniment of watercourses, verify it for each individual category of watercourses and formulate principles of measures to improve its status. The methodology for the assessment of vegetative accompaniment was developed on the basis of literature search and field experience. The ground of the assessment is a field...

Thickness of the bark has serious influence on the round wood volume inside bark, if the diameter is measured over bark. The measured value of the bark thickness depends on measuring method. To analyse the possible bark thickness differences of spruce, given by different measuring methods and Peintinger's bark thickness tables and to calculate the corresponding round wood volume differences, given by different bark thickness deduction compared with the Czech Standard is the principle goal of presented research.Three ways of bark thickness measuring were realized: by using bark gauge, increment hammer and slide caliper. Bark gauge gives the highest...

High-powered means of slaughter chickens production cause on certain individuals abnormal biochemical development of postmortal changes in their muscles. It consequently lead to interferences of sensory quality of the chicken meat. So called myopathies of the chicken breast meat occur in the low extent. It is typical variation in dark colouring of breast muscle.Veterinary supervision confiscates chickens embodying myopathy by reason of sensorical unacceptable dark muscle colour. Deepness of colour is evaluated by adspection of veterinary supervisors. It is tendency leading to find out objective parameters for evaluating this sensual chicken meat...

Acta Univ. Agric. Silvic. Mendelianae Brun. 2006, 54(5), 57-64 | DOI: 10.11118/actaun200654050057
The objective of this contribution is to interpret the impact of some abiotic factors on the germinability. Primarily was observed the stress that they cause on germinability and also on the energy of other perennial grass caryopsis' germinability. Withal there were considered differences in germinability of some perennial grass species, variances of strains and the influence of today's seeds dressing technologies, which are used to improve the germination.The light factor has the biggest influence of all factors on germination of Agrostis stolonifera (Penn G-2, Providence), Poa supina (Supranova) and Poa pratensis (Julius, Julius...

The evaluation of grapevine genetic resources is very important especially from the viewpoint of the use of some varieties within the process of grape breeding. At present, the breeding of grapevine is more and more focused upon selection of varieties showing an increased resistance to fungal diseases and, especially to downy mildew. At the Faculty of Horticulture, we have studied the resistance of 32 grapevine varieties to downy mildew resistance on leaves. This evaluation took place under field conditions in a vineyard that was not treated with pesticides within the period of 1996-2000. The resistance to downy mildew was evaluated using a scale published...

The study was an in vitro analysis of bovine blood neutrophil apoptosis and necrosis based on the detection of their morphological and biochemical features. The experiment was carried out in six clinically healthy Holstein x Bohemian Red Pied crossbred virgin heifers aged 16 to 18 months. The fresh and in vitro cultivated blood were analysed by light and electron microscopy and flow cytometry. In fresh blood, non apoptotic or necrotic neutrophils were found by light microscopy. On the other hand, 3.34% apoptotic and 0.32% necrotic neutrophils were detected by flow cytometry. After four hours of incubation, 3.53% apoptotic and 1.37% necrotic...

The objective of the present study was a detailed analysis of the body conformation of the Old Kladruby horse in the Stud Farm Kladruby. We applied 26 body dimensions, 9 angles of extremity joints and 12 hippo-metrical indices of 167 breeding horses to analyse the population according to the colouration (grey, black), lines (9 lines), sex (stallions and mares) and age categories (4 classes). The resulting measures were analysed statistically by means of a linear model with fixed effects (GLM). Most of the statistical highly significant differences were differences detected between stallions and mares and between the Old Kladruby grey and black horses....

In the present study called "An Ethological Study of Young Horses" we focused on the behaviour of foals from their birth to separation from their mother. We observed and analysed their behaviour and daily activities, and from the achieved results we drew conclusions for practical horse breeding. We studied the following forms of behaviour of the foals: feeding behaviour (sucking, drinking, eating roughage and concentrates, gleaning, coprophagia), defecation and micturition, comfortable behaviour and mutual comfort behaviour, manifestations of relaxation (resting posture, lying down), movement manifestations, playful behaviour, stereotype behaviour,...

In this paper "Environment influence on the solidity of the adhesive joint" I have dealt with the utilization of the bonding metals and practising experimental laboratory tests of adhesive joints depending on different laboratory environments and anticorrosive protection of the samples.For this laboratory tests I have chosen a universal adhesive. It is a two-component epoxy adhesive with suitable conditions for bonding metals. The samples were made from steel and were produced by the standard ČSN EN 1465. After the bonding and the cure procedure the samples were exposed in H20 environment for exact intervals (parts of the samples were...

Acta Univ. Agric. Silvic. Mendelianae Brun. 2006, 54(5), 149-154 | DOI: 10.11118/actaun200654050149
Genetic variability was detected in 15 varieties of triticale (XTriticosecale Wittmack., 2n = 6x = 42, BBAARR) registered in the Czech Republic by means of polymorphism of DNA using the RAPD method and the SSR method. For detection we used 80 RAPD primers. The lower reproducibility of the RAPD markers was resolved by means of repeated analyses (3-4 times). On the basis of statistical evaluation a dendrogram was set up, which allows highly significantly to differentiate the varieties Kolor, Modus and Tornado. The remaining 12 analysed varieties formed 4 clusters. In addition to the RAPD markers a protocol of detection of DNA polymorphism was...
