Anaerobe degradation of maize infected by Fusarium graminearum
57-61Views:123Last year intense rainfalls and moisture conditions were beneficial for the Fusarium sp. in Hungary. Fusarium strains decrease cereal quality (for example maize), furthermore may cause yield loss. Due to the toxin production, the fungi have a dangerous animal and human pathogen effect (Placinta et al., 1999).The effects of the Fusarium infection and its mycotoxin production haven’t been perfectly eliminated. Fusariumgraminearum
is the most common agricultural pathogen in Hungary. The utilization of infected maize as an alternative biogas raw material may be an efficient and environmentally friendly disposal method. In this case, Fusarium-, and mycotoxin-content of the maize have to be analyzed as well as the impact of these factors’ on the biogas production process. Our experience was based on the raw material basis of a biogas plant. Different amount of Fusarium free and infected maize grits have been added to the regular raw material mixture. The detection of Fusarium fungi has been analyzed
in experimental digesters throughout the different stages of mesophilic digestion. In the biogas liquid end product the Fusarium was detected by breeding and by microscope. According to our results, the Fusarium sp. was not detectable in the liquid end product after 30 days. -
New Integrated Breeding Evaluation Method Used for German Warm-blooded Horses
3-6Views:97In Germany, the new integrated breeding value estimation is based on a multiple-trait animal model, considering simultaneously information from performance test of stallion on station, performance test of mares as well as competition results of sport horses. The objective of this study was to estimated the genetic parameters of the traits used in the integrated breeding evaluation including all German warmblood breeds. The analysed data consisted of 4527, 40670 and six million records for performance tests of stallions, mares and for competition results, respectively. Genetic parameters were estimated with a multivariate BLUP animal model. Heritabilities for traits obtained from stallions tested on station ranged from 0.33 (jumping under rider) to 0.51 (trot) and for the traits from mare performance test from 0.27 (walk) to 0.38 (trot). Genetic correlations between corresponding traits recorded on performance test of stallions and mares ranged from 0.87 (canter) to 0.98 (free jumping). Heritabilities of competition traits from horses (build up for sport) were estimated as 0.12 and 0.11 for dressage and jumping, respectively. The use of all traits for estimation of genetic values of horses is expected to reduce pre-selection and optimal combines all information resources based on the estimated genetic parameters.

Relationships of the sport and the life quality in the University of Debrecen
87-96Views:155In the sport- life of the University of Debrecen there has been a demand formulated on the making of a comprehensive, long-term development plan, which obviously incorporates all
fields of sport. This document guides the way for people in the sport- life of the university how they could organise their activities connected with sport on a calculable, predictable level.
Necessarily, the preliminary collection of professional informations has been a basic requirement for the establishment of this document.
The program provides foreseeable instructions to the organisation of sport pursuits both for sport people in the university, and members of the sport spehere in a wider sense. It
offers a cohesive solution for all kinds of tasks defined with the sport life, and also gives a guidance for the various ways of realisations of these challenges. Thus it can answer such questions as for example how the university can conduce the initation of conditions for the healthy living through spare time sporting, how it can participate in the financing of contest sport with the contributing project of reinforcement training and how the university can support the sport life of handicapped people. The project also contributes to the cultivation of the sport traditions of the university by bankrolling not only the official university sport
life but also the leisure time sporting of the students.
On the basis of rethinking the situation of sport at the university with its future possibilities the program paraphrases the tasks of the university in the sport life, the long term aims of
university sport politics with its operative aims that should be performed and also the possible steps which lead to these purposes.
The target of the project is to turn the University of Debrcen in every field into a “Sporting University”. It means, that beyond the development of quality sport and outstanding contest sport a much wider range of university people should be included in sporting in order to utilize all the advantages of sport. With this the physical culture could become not only a substantial form of spending our free time, but with getting one of our natural everyday activities it can also become our lifestyle.
Sporting prominently contributes to both the university students’s and the whole society’s mental and physical wellfare, and it also helps to improve our helthstate on various fields of life:
with its special functions it is a means for establishing a healthy nation, for promoting common relationships, for nourishing the economic activity of people and also for strengthening the national values and one’s self-esteem through providing equal opportunities.
The prosperousity of contest sport at the university and the maintaining and protesing of its efficiency fortifies our selfregard, as it is able to hold appropriate sportsmen up as examples
to both present and future universtity students, and also offers exacting ways of entertainment. Besides all these the advataged purpose of the project is to find and delibaretaly include those
necessary mechanisms which are needed for the working of the sport market. -
Effect of M9, MM106 and Seedling Rootstocks on Sunburn-Sensitivity of 33 Apple Cultivars, and Sunburn Effects on Fruit Quality
236-247Views:77The purpose of this study was to investigate the sunburn-sensitivity of 33 apple cultivars grafted onto 3 rootstocks (M9, MM106 and seedling) in a commercial orchard at Nagykutas (in the western part of Hungary). The authors also searched for any relationship between fruit quality parameters and the frequency of sunburn on the fruit surface.
During the observations, the cultivars had rootstock-specific properties in respect to sunburn-susceptibility. Accordingly, the injury decreased in the order M9, MM106 and seedling rootstocks. The differences in the sensitivity were founded on the foliage-morphological characteristics of trees, caused by the growing vigour of the rootstocks. Accordingly, the highest value of sunburn injury was observed on M9 rootstock, because this rootstock has a dwarfing effect on the grafted main cultivars. Thus, the vegetative area of these trees grew very slowly and the foliage was not compact enough to protect the fruits from the strong rays. The largeness and density of the foliage increased in the order M9, MM106 and seedling rootstocks. Relationships were also demonstrated between the diameter of the upper part of crown, the size of leaves, the number of fruits per tree and the injury from sunburn.
The damage values showed, that the gravity of symptoms did not decrease below a well-defined level of dimension on fruit. Determined potential area of injury was necessary for the symptoms to become visible.
The authors categorized the cultivars in the respect of values of sunburn frequency: I. „Not sensitive”, II. „Moderately sensitive” and III. „Very sensitive” categories were constituted. Generally, the Gala cultivars showed low damage (or were free of symptoms), in contrast, Golden mutants suffered relative strongly. The most sensitive cultivar was Jonica on all three of rootstocks.
We searched for any relationship between the fruit quality parameters and the frequency of sunburn. A significant correlation was found in the cases of fruit weight and colour-coverage. The latter can be related to that fact that highly colour covered fruits are found on the peripherial part of crown, so these are exposed to stronger sun rays -
e-services for the farmers
11-19Views:102Nowadays the different IT tools and use of the internet have appeared almost in every sectors of the economy, so it may give several benefits and help to the agricultural producers. In this article I give a brief overview about e-government and its’ opportunities, then I give a short description of a few important governmental and specialized administration on-line services which are provided to the farmers. According to many experts using of informatics may cause essential change in the operation of the administration because of the fact that the electronic administration may evolve. Generally speaking, today the egovernment services are already an indispensable device to the reformation of the public administration, the modification of services which suits to people's demands and the creation of the more adaptable, clearer public administration. The electronic
documents are free from formal errors which is either important for clients or offices. The cases can be arranged even from home in 24 hours of the day. The spread and success of the use of electronic services depend not only on the quality of services, but the IT readiness of the target audience is also very important factor. Unfortunately the affect of e-gap is bigger in case of the farmers. -
A gombatermesztés szerepe az átalakuló magyar mezőgazdaságban
15-22Views:83The structure of Hungarian agriculture should be changed before the EU accession. The new structure should fulfill EU requirements and also produce competitive products. Unconventional products (mushroom, fish, honey etc.) have a lot of advantages: they can be produced on small farms, their trade is mainly free of regulation and their markets are almost unlimited. This paper deals with one of these alternative agricultural enterprises, namely mushroom production. Hungarian mushroom production – in spite of difficulties – has witnessed remarkable expansion: it has increased its production by fourfold and its export by fivefold in less than ten years. The low level of wages gives Hungary significant advantage over its competitors. If we could ensure the appropriate infrastructure (technical advice, bank loans, etc.) the mushroom industry would become one of the most profitable sectors of Hungarian agriculture.

Intensity of free radical processes in the leaves of arboreal plants under act of industrial dust borne extracts
83-87Views:61The influence of industrial pollutants on the intensity of lipid peroxidation in the assimilatory organs of arboreal plant was investigated. The differential changes of the probed indexes are set depending on the species. Information is got can testify to participation of lipid peroxidation products in forming of reactions-answers of arboreal plants on influence of industrial dust borne extract with content of heavy metals. Determination of level and rates of accumulation of Zn, Ni, Pb and Cd, in the leaves of arboreal plants in the conditions of different
contamination level allowed to take species to two groups. To the first (phytoextraction potential exceeds a base-line level in 10 times) belong Populus bolleana Lauche, P. italica (Du Roi) Moench, Picea pungens Engelm and Sorbus aucuparia L. To the second (exceeds a base-line level from 5 to 10 times) belong Acer negundo L., Aesculus hippocastanum L., Betula pendula Roth and Tilia cordata Mill. The most substantial increase of peroxidation secondary product content (more than in 2.5 times) is peculiar for B. pendula, A. hippocastanum and P. pungens Engelm., that well conforms to the rates of heavy metals translocation, it has however species-specific character.
