Adaptation of temperate climate horticultural plants in tropical and subtropical developing countries II. General characteristics, Hungarian experiences and possibilities
5-11.Views:400The cooperation of Hungarian professionals with Chinese, Thai, South-Korean, Taiwanese and Brazilian colleagues should deserve much more attention than actually done. We refer to the transfer and adaptation of production technologies as well as biotechnological developments in vegetables, fruits, ornamentals and medicinal plants from the Temperate Zone to the tropical and subtropical regions. According to our information Hungarian colleagues involved in extension work are highly esteemed on the same level as Japanese, Chilean, Italian and French colleagues. We could state that immigration of investors, local enterpreneurs as well as those coming from expansive regions of Europe, North America and oversses, representaives of supermakets keeps to be accelerated by the increasing confidence triggered also by the successful management of profitable plantations, vineyards and fruits initiated first about 15 years ago.
For Hungary, the presence and achievements of Hungarian horticultural expertise in tropical and subtropical zones yielded unequivocal advantages. Therefore, the next actual step of development would mean the organisation of a network of the "Units of Horticultural Mission" in the tropic and subtropic countries. We are convinced that those Units will stimulate the traffic of technologies as centers of transfer within and between the regions and contribute to the increasing influence of professionals on the production and trade of horticultural commodities. The introduction and testing of new varieties of vegetables, fruits, medicinal plants (as well as ornamentals), the development of the growing technologies, adaptation and acclimation of Temperate Zone germ plasm representing the general trends of advanced production will be the most important tasks of the Mission with a sufficient oversight upon the whole world. It is taken as a fact that Hungarian horticulture and breeding is competitive on the world market. We are ready to contribute to the development of horticulture on a worldwide scale. The Hungarian R & D will be attentive in the future to manage the accumulated capacities by information and mediating needs and offers to the volonteers of the profession. The reality of the above propositions are amply proved by successes of the Agroinvest Co and of other professionals registered in abroad.
To keep on the top of the world list of the profession we have to follow up the international trends by our permanent presence on the most important centers of administration and production of the world in order to hold on the hot line of the Hungarian administration competent in financing the R & D activities. We need specialists which are open minded, speak languages, familiar with the tricks of informatics, economics and politics, competent in deals, able to make decisions, etc. The education and training should be strenghtened to he conform with those trends. That proposal involves also the need to follow up the activities of the transnational companies, the regular, active participation on international conferences, the permanent attention paid to electronic informations available in the worldwide networks as well as the printed periodicals of horticulture. It is also related to the attraction of investors to the developments aimed within the country as well as abroad. At last but not at least we have to keep in mind that the work performed abroad by the Hungarian professional is a kind of "para-diplomatic mission" which cannot be substituted by any other, sometimes very expensive activity charged on the officia erliplomatic missions. The benefit of it is, however, valid to the whole country because false stereotypes developed during the last 50 years cannot be abolished otherwise.

New trends in selection of poppy (Papaver somniferum L.)
69-75.Views:270Since the isolation of morphine by Sertümer in 1805 more than 40 alkaloids have been isolated from the poppy (Papaver somniferum L.). Some of them have high biological-pharmacological activity and economical importance, while others have none, or restricted ones. The increasing demand for poppy alkaloids is the consequence of the widening of the medical application of morphine and its related compounds: the quantity of morphine used for the treatment of pain reached a record level of 17.9 tonnes in 1997, compared with an annual average of 2.2 tonnes used during the period 1978-1983. However, the production of raw material (either opium, or dried capsule is produced) has to be re-evaluated taking into consideration the UN Convention signed in 1988 against Illicit Traffic in Narcotic Drugs and Psychotropic Substances. The countries were forced by the Convention to introduce new arrangements in poppy production including selection and introduction of new cultivars.
In the present work up to date results of poppy selection are reviewed explaining the biosynthetic and eco-physiological background of their alkaloid accumulation. The effectiveness and the possibilities of traditional selection methods as well as the probability of the application of biotransformation for producing cultivars accumulating low or high alkaloid content or plant material with special alkaloid spectrum (codeine, thebaine, narcotine) are discussed. The examples of Hungarian cultivars 'Monaco', 'Kék Gemona' and 'Tebona' are given in more detail.

Comparative organoleptic examination of apple varieties developed by different environmentally safe technologies
69-70.Views:144Ecological or biological growing techniques are generally recognised as actual trends in agricultural production. The objective of our experiments is a comparison of apple fruits grown alternatively by integrated versus ecological technology. In a collection of varieties, the possibility of the experiment was feasible. At the same time, a comparison of the popularity of existing varieties was also actual. The organoleptic consumer’s tests rated the varieties, and the comparison with instrumentally raised “objective” data could be compared with the subjective ratings, which did not coincide with each other. This phenomenon was revealed in the rating of acid-sugar harmony, where the internationally used quality index of Thiault produced a different range of the samples then the consumer’s test. The same contradiction was observed between ratings of firmness and the data raised by penetrometer.

Spatial and temporal variation of extremely abundant maxima of precipitation in Hungary during the period between 1951 and 2010
107-114.Views:252The study deals with the accumulated database of 16 meteorological stations in Hungary during a period of 60 years. The purpose was to reveal the spatial and temporal structure of the appearance of extreme values in the daily distribution of data concerning precipitation. We strived to answer the question whether the frequency of incidences of daily maxima did they change or not during the 60 year-long period in the main growing regions of the country. It is demonstrated on geographical maps how the size and frequency of precipitation episodes ensued, and what are the typical traits of changes in intensity as well as in frequency of happenings projected according to their spatial and temporal distribution. From the point of view of fruit and vegetable growing, it is of prime interest what kind of frequency and intensity of changes occurred in precipitation. The temporal distribution of extremities though did not seem to change signifi cantly in some areas, but the recognition of changes may help conspicuously the planning and the choice between alternatives of species and varieties as well as technologies of horticultural managements for the long run. Extremely intense rains during a short time may cause erosion and stagnant water, thus we have to know what are the odds of risk. The temporary distribution of changes helps us to judge upon the reality of anxieties, which are expected according to the existence of trends. Seasonal or monthly distribution is visualised by maps, what is expected and what is accidental as for a decision in planning. The spatial distribution of coeffi cients of variation help us to decide what is the local chance of extreme happenings at different parts of the country and what is its coeffi cient of uncertainty. The risk of any undertaking dependent on conditions of weather could be expressed numerically by a coeffi cient of risk.

International comparative analysis for enterprise resource management on the developing wine market of China
27-30.Views:175However grape cultivation has long tradition in China, modem grape wine and wine production has only started 10 years ago, parallel with the Chinese economic boom, in 1998. The rise of the social welfare caused a higher demand for luxury products, wine drinking came more popular, since on the one hand it is representing the standard of western style living for the higher society class, on the other hand Chinese people can live a more healthy life and spend money on wine drinking, instead of drinking traditional spirits. This tendency opened a wide market for Chinese and international grape producers and winemakers. During our research we have collected the rare, available market information on the Chinese wine market. With the use of this statistical data we will analyse the collected information and rough out the future trends and opportunities and threads for trade companies on the emerging wine market.

Consumer buying behaviour of fruit and vegetables in the Netherlands
81-90.Views:389The Dutch Households bought in 2010 compared with the year before a little less vegetables and less fruit. However because of a higher price level the supermarket sales of fruits and vegetables increased with 7% to almost €3 billion. A Dutch household bought 72.4 kilo fresh vegetables in 2010. This is 2% less than in 2009. Tomatoes are the most bought vegetable followed by onion and cucumber. Although the Dutch households bought less vegetables, the spending increased with 5%. The average price of vegetables was 7% higher than in 2009. In 2010 a Dutch household bought almost 88 kilo fresh fruit. Compared with 2009 this was 2% less. Apple is far out the most popular, followed by orange and banana. Also the spending on fruit decreased a little, specially on strawberry, kiwi and banana. The sales of vegetables is realized for almost 90% by the supermarket channel. Albert Heijn has a market share of 38%, followed by Superunie and C1000. Also for fruit the supermarket is the most important retail channel. However fruit is also sold for 20% in grocery stores and markets. The total turnover from supermarkets of vegetables was in 2010 over €2 billion, 8% more than in 2009. 85% of this is fresh product (fresh and pre-treated). Canned vegetables become less popular. The turnover was decreasing 2% to just under €200 million. Green beans are the most popular, followed by peas and carrots. However more money was spend on frozen vegetables (+5%) and pickles (+1%). Over 40% of the supermarket turnover of frozen vegetables is spend on spinach. The supermarket turnover of fruit increased in 2010 with 3% to €1,25 billion. From this 93% is fresh unprocessed fruit. The turnover of pre-treated (washed and sliced) is increasing, but still not more than 3%. Although with a modest share, the spending on frozen fruit also increased in 2010 to €5,5 million. The turnover of canned fruit however was decreasing with 6% compared with 2009. The supermarket turnover of pre-treated fruit was €35 million. Albert Heijn is the absolute market leader for pretreated fruit. In 2010 70% of the sales was realized by Albert Heijn. Mixed fresh pre-treated fruit, mainly fruit salads, account for 40% of the total supermarket turnover of processed fruit. Canned pineapple is the most important canned fruit in supermarkets, followed by fruit cocktail and peach. There is a high degree of awareness of consumers regarding the “must” to use enough fruit and vegetables. Despite of this, consumers do not always eat enough healthy products. Reasons for this are the busy life of the modern young people and the perception that vegetables are “not easy” to use. Therefore preparing a meal has to be easy and fast with suitable products Here is an important task for concept and product development.

Economic figures of sour cherry production at national level of Hungary
107-109.Views:158After the political changes of 1989, economical processes impaired heavily the Hungarian fruit growing branch, more particularly production of sour cherry. Paralleling with the increasing mass of production, producer’s prices dwindled drastically. At present, Hungarian growers cannot cover the costs of production, nay, hardly raise income. My purpose was to analyse the cost and income relations of the sour cherry branch during the period of 2002-2009 years in order to find out what are the decisive features, which reveal the trends to be considered. The data presented in the paper are means of a heterogeneous population of values, which cannot be utilised for immediate use in management, but they may reveal the challenges and tendencies of economics of the branch.

Development and trends in fruit growing
29-44.Views:158In the development plan of fruit branch related to 2005, resp. 2010, the authors anticipate a 27, resp. 53% increase. They presage in the apple production a 40, resp. 61 % increase as attainable. As far as stone-fruits are concerned, the prognose amounts to 10, resp. 61% increment. (Except the sour cherry with 25 to 61% increase.) To hit the target they are planning until 2002' 4000 ha new plantations yearly. In their opinion there is a need of state subsidy (during the 3 years altogether) Ft 21 billion.

Economic figures of apple production at national level of Hungary
Views:161After the change of the political system the main looser was in Hungary the fruit-growing branch. The yields varied at high amplitudes, and the production increased slowly in spite of multiple planting activities. The European Union ranked fruit production “loosely” to the products, which allows the extension of its markets. Thus I decided to analyse the economic relations of the period between 2002 and 2008 in order to reveal the main effects of movements. The pictures are the resultants of a heterogeneous population, which cannot be influenced on the level of enterprises. But they are utilised for the recognition of challenges and trends on the level of branches of economy. The immediate costs increased the production monotonously, which cannot be compensated by a thrifty management of the general costs. Thus costs of production increased dramatically, whereas the marketing of products could not realise the values.

Water use of young apple trees related to leaf area development
61-63.Views:131Present paper describes an investigation concerning seasonal water use and foliage area development of apple trees. Sap flow velocity was measured in the trunks of five years old apple trees cv. `Florina'/M.26 by a thermal dissipation (Granier) method from 20th of May to the end of September in 1998. The development of foliage area was estimated by a method including leaf area measurements, recording of leaves and shoot length. The foliage area reached to 70% of the maximum yearly value at beginning of June. The remaining 30% developed to the end of August. The leaf area specific water use was considerable higher in June and July, than in second part of summer. The trends of ET-FAO and water use curves differed mostly in the late season: the ET-FAO curve falls quite in September compared to August, whereas the value of water use was a similar as in August. This insensitivity of ET-FAO in this period may be a great disadvantage while using the Penman-Monteith equation in irrigation scheduling of apple.

The future of the Hungarian sour cherry growing branch
99-104.Views:191The present study deals with the actual situation of the Hungarian sour cherry production in order to outline the chances of the future and the trends of the development anticipated. The general conclusion accepted that on the long run Hungarian sour cherry production ought to be reorganised. The conditions of keeping the position on the international market are outlined: integration of small farms into large plantations (several times 10 hectares), introduction of mechanical harvest and high (15–20 t/ha) yields. For all that, adequate expertise should be developed on the cooperative farms, where the up to date technology could be applied with innovative initiatives. Small farms (up to 1–2 hectares) and home gardens have no chances to stay on the competitive market. The actual volume of sour cherry of 40–70 thousand tons per year cannot be increased in the future. The sour cherry area was 16 000 ha in 2001, the actual is around 12–13 thousand, and will decline during the following 5 years to less than 10 thousand hectares.

Effect of the terroir and the harvest time on the Kékfrankos grape berries sensorial properties in Eger (Hungary)
87-92.Views:158In this research the effects of the production site “terroir” and the harvest time on the most important organoleptic properties of the berries of Kékfrankos (Blaufrankish) grape variety were observed. The follow-up of the maturation process in a given parcel can effectively supplemented by the results of sensorial evaluations of the grape berries. In most cases, the tasters found significant differences in sensorial characteristics of the berries due to the harvest time, although the trends of each parcels were different. Significant differences were frequently found in the result of the observed terroirs.

Cultivars, marketing and integrated Production of apples in the Czech Republic
87-92.Views:108Development in apple production in the Czech Republic has been adversely effected during a few recent years by escape of capital investment from the agrifood industry (due to privatisation, restitution and transformation). On the other way round the competition on the domestic market is much higher than it was before because of unlimited import of subtropical and tropical fruit and some import of traditional fruit species as well. Therefore fruit growers are very much concerned in any possible means (which are not economically feasible) to be more competitive. One of the most common approach is the use of new cultivars bred in the country which are resistant or tolerant to diseases and offer better quality both for fresh market and processing. Another way for increasing competition ability for fruit growers is the join and mastering of integrated production which also considerably improve the quality of fruit as far as aspects of health are meant.

The future of the apple growing branch in Hungary
91-98.Views:197The present study deals with the actual situation of the Hungarian apple production in order to outline the chances of the future and the trends of the development to be anticipated. The general conclusion is accepted that on the long run Hungarian apple production ought to be reorganised. The conditions of keeping the position on the international market are outlined. The main concern is the aging of the plantations, i.e. 40%of them being more than 25–30 year old, and produce apple being suitable for processing only. Organisation of growers is rudimentary, export markets are limited, and buyer’s market is everywhere dominant and is getting more severe. All those circumstances anticipate the reduction of the apple growing branch from the present 35 000 hectares to 15–20 000 hectares within a period of less than 10 years.

Effect of the terroir and the harvest time on the Kékfrankos grape berries visual and physical parameters in Eger (Hungary)
81-85.Views:152In this research, the effects of the “terroir” and the harvest time on the most important physical properties of the berries of Kékfrankos (Blaufrankish) grape variety were examined in 2010 and 2011. The results of the experimentation shown, that the maturation processes can be well described by different physical parameters of the grape berry. The terroir and harvest time effects were investigated in two different vintages and four different territories. It can be concluded, that these physical parameters change significantly during the ripening period, but trends differ between vintages and regions.
