  Between 1950-1989, the production and trade of ornamental plants in Hungary was characterised by meeting the demands of the home and that of the Eastern-Block market and by a minimal external trade with the Western countries. After the socio-economical changes in 1989/90, the trade of flowers gradually became liberalised and the Hungarian growers had to face the concurrency of steadily increasing import from the West and from all over the World. This tendency coincided with the physical and mental degradation (outdating) of most of the glasshouses, along with the decline of several former large growers of the communist type (state or cooperative), the appearance and growth of new private companies and the building (rebuilding) of new plastic houses and (mainly second-hand) glasshouses. In spite of the above-listed problems, the production as a whole did not (or only slightly) decrease and/or even an increase occured in many areas mainly in the open-ground production. In 1998, the protected flower cultivation comprised round 110 ha of glasshouses, 180-220 ha of plastic structures and 3-5 ha of frames, with the main crops as follows: cut flowers and cut foliage 220-240 ha; pot plants (with geraniums) 30-40 ha; bedding plants (without geraniums) 20-25 ha; "transit^--greenhouses (for redistribution only) 3-5 ha: other (eg. propagation of woody ornamentals) 3-5 ha. The structure of open-ground production was as follows: Total 1150-1210 ha, including: Nursery products: woody ornamentals 880 ha; perennials 10-15 ha; rose bushes 30-35 ha. Other open-ground crops: flower bulbs 50-60 ha; dried flowers 130-140 ha; open-ground cut flowers 25-30 ha; flower seed 30-35 ha; (biennial) bedding plants 10-15 ha.

  In this study, the susceptibility of 7 commercially important sour cherry cultivars to Monilinia laxa was studied. Artificial inoculation was made with M. laxa isolates, which were isolated from different woody plants. Artificial inoculation was prepared in the laboratory and in the field. In laboratory, flowers of sour cherries while in the field, the two-year old twigs were inoculated in 2006 and 2007. According to results of stigmata inoculation, there were infection ability differences among the isolates originated from five different stone fruit host. Cultivars could be sorted into two susceptibility groups. In the field, twig inoculation in 2007 was made at blossom period and in 2007 at harvest. Seven sour cherry cultivars were inoculated with 8-day-old mycelial culture of M. laxa originated from sour cherry and almond. The agressivity and pathogenicity of the two isolates were measured by the degree of floem death: Results showed that year and phenological stage considerably influenced the degree of symptoms caused by the fungus. After artificial inoculation, tissue death progression was studied by fluorescent microscope. According to results, sour cherry cultivars were sorted into disease susceptibility groups. Susceptibility orders were identical to results on stigmata inoculation.

  The main fields of open ground ornamental plant cultivation in Hungary are: Woody ornamental nursery products (trees, shrubs, conifers) (950 ha cultivation area and 4-6 million plants sold per years^.; Rose bushes (around 140 ha and 2-4 million bushes per year); Perennial plants (20-30 ha and 3-4 million plants per year); Dried flowers (200-250 ha of land and a production value of 5-700.000 HUF per year). The paper is discussing in detail the structure, development and tendencies of ornamental nursery production (with figures in tabulated form) and later gives shorter assessments of the present state and perspectives of the other three fields. Finally, a list is given of the Hungarian professional associations and unions, education and research centres involved in ornamental plant growing and trade.
