Kaššák, Pavol
Dissertation thesis is aimed on the valuation of the chosen taxons of irises from subgenus Limniris in the conditions of middle European termophytics, concretely in the climatically conditions of the Lednice, south Moravia region. Valuated were thirteen signs (length, width and colour of the leaf, height and width of flower, colour of sepals and petals, height of flower stem, number of the flowers on the flower stem, whole amount of flowers on plant in the third growing year, clump compactness in the fourth growing year, smell of the flower, flowering date) in sixty nine taxons (11 species).

Klenzová, Tereza
The bachelor thesis was discussed in the institute of vegetable growing and floriculture of Faculty of Horticulture in Mendel University in Brno, Lednice in the periods of the years 2010 -- 2011. The thesis is mostly focused on description of Irises, group limniris, list of diseases and pests on irises and suggestion how to cure them. Diseases and pests have been observed and collected, on collection area with irises in ZF, Lednice three times, within vegetation. All described damages have been found on second collection, in efflorescence. Irises have been damaged also by wrong growing conditions, such as unsuitable watering, insufficiency of nutrients, wrong pH and unsuitable soil structure. Amongst viruses found on these irises it was mainly mold grey iris (Botrytis cinerea) and dry spottiness on leaves of iris (Davidiella macrospora). Snails (Pulmonata), Mononychus punctumalbum, Oxythyrea funesta, common earwig (Forficula auricularia), leaf aphids (Aphidoidea), ants (Formicoidea) and Acronicta sp. are mostly occuring pests on these collections. Mostly damaged species was I. sibirica, what means, that although it is most cultivated species in our country, it is not going that well. For determined location it can be recommended mainly prevention and biological protection such as natural enemies of pests and plants, which repels pests. In case of persistence in occuring of pathogens, it would be better use chemicals (Rovral Flo, Captan 50 WP, Saprol New, Decis 2,5 EC, Actellic 50 EC, Furadanu 5G, Aztec 140 EW or Pirimor 25 WG). These chemicals can, in wrong usage damage plants, so prevention and biological protection is recommended first, and it is also eco friendly.

Závišková, Lenka
Bachelor thesis go about description genus Iris and each groups, evaluation of cultivars Iris sibirica. From school lands Faculty of Horticulture in Lednice were evaluated fifteen cultivars.

The best from evaluated was Iris sibirica 'Dance Ballerina Dance', Iris sibirica 'Fourford White', Iris sibirica 'Marantha', Iris sibirica 'Sea Shadows', Iris sibirica 'White Swirl', Iris sibirica 'Zweiters Hundred', this cultivars had the most blossoms. From aesthetic aspects it was Iris sibirica 'Fourfold White', which has the biggest blossom and the widest blossom has cultivar Iris sibirica 'Zweiters Hundred'. The best cultivar from garden aspect it was Iris sibirica 'Strandperle', which was the highest from all cultivars. All reviews cultivars weren't susceptible to attack by pathogens and pests apart from Iris sibirica 'Fourfold White' from which was found presence of Aphis fabae and Iris sibirica 'White Horses' was found Mononychus punctumalbum.
