Bekeová, Johana ; Matiska, Pavel (advisor) ; Markéta, Markéta (referee)
Iris barbata are among the perennials and their bearded representatives can often be found in our gardens. Cultivars, with successive breeding beard has changed to the crest, horn, spoon, flounce or the pom pom and was replaced by different colors, it calls Space Age irises and because their appearance is not too popular in according to gardener and therefore this thesis is moving towards an evaluation of their decorative and vital potential and recommendations for public sale. Ten middle and high irises were evaluated from late April to mid June 2015, when the iris gradually bloomed in the area Chotobuz in the Botanical Garden in Pruhonice. It reviewed, according to the Classification of Iris from Ing. Milan Blažek and the results were documented by photographs taken 1x or 2x per week, depending on the speed of the newly blossomed individuals. All irises have a sunny, well drained, sandy-loam habitat on a gentle slope. Rated irises come from Czech and foreign breeders and their flower color, plant height, shape and color of bread and resistance to diseases and pests, they differing with each individual. The authenticity of the individuals are verified in accordance with original labels from the American Iris Society. Irises prevailed in violet, yellow or white with all five shapes of bread with orange color at the center. The worst hit from the selected iris cultivar is the Hyperspace because it was heavily attacked by diseases and do not fit to cut and he had created a flounce instead of a spoon. Due to the low vitality of the plant was not recommended to resell. Conversely, the best hit of decorative and vital perspective is the High Point, which rendered colorful color. In the case of the cultivar Mesmerizer had imperfect flower, which was present shape of the beard like pom pom and also a crest. For other cultivars was a change in the overall height or change the shape of the beard (Capricious Candles) or flower color. The aforementioned factors were bad probably due to insufficient energy plant or a higher temperature at the time or prolonged drought, and in some cases slight differences hereditary characters. In addition to the cultivar Hyperspace may be other individuals recommended for sale and planting in our garden or to cut.
