A rapid, simple and efficient protocol for in vitro multiple shoot induction and plantlet regeneration was achieved from three different explants of Cicer arietinum. The explants viz shoot tip, cotyledonary node and node were cultured on MS medium fortified with Benzyl Adenine (BA) (0.44-8.88μM) for multiple shoot induction. Multiple shoots proliferation was best observed at 4.44μM BA from all the three explants within two weeks of culture. Of the three different explants tested, cotyledonary nodes produced the maximum number of shoots. Shoot number per explant ranged between 7 and 15. Individual shoots were aseptically excised...
Nutritional composition and yield of endive cultivars - Cichorium endivia L.
M. Koudela, K. Petříková
Hort. Sci. (Prague), 2007, 34(1):6-10 | DOI: 10.17221/1848-HORTSCI
Two year trials at the Horticultural Faculty in Lednice (part of the Mendel University of Agriculture and Forestry Brno) evaluated six cultivars of endive (Cichorium endivia L.): 3 cultivars of C. endivia L. var. crispum (Markant, Midori, Protos), and 3 cultivars of C. endivia L. var. latifolium (Malan, Maral, Nuance). At harvest time, the nutritional composition was evaluated: levels of vitamin C, minerals (K, Na, Ca, Mg), chlorophyll, dietary fibre, dry matter and nitrates. In addition, a single plant weight and yield were measured. It was observed that the cultivars of C. endivia var. crispum contained...
The study of irrigation influence on nutritional value of Lonicera kamtschatica - cultivar Gerda 25 and Lonicera edulis berries under the Nitra conditions during 2001-2003

Two species of edible honeysuckle were studied in the trial established in the autumn 1994. The spacing used was 2.0 × 1.5 m and the experiment included irrigated as well as non- irrigated variants. The aim of this study was to provide a summary of nutritional values of Lonicera kamtschatica and Lonicera edulis berries under the Nitra conditions during the period 2001-2003. The berries were examined for the content of dry mater, sugar, organic acids, ascorbic acid, mineral substances - K, Ca, P, Mg, Na and anthocyanins from pomace and juice. The results of our experiments refer to the exceptionally high content of ascorbic acid ranging...
Morphological and chemical variations of sweet flag (Acorus calamus L.) in the Czech and Finnish gene bank collection

Hort. Sci. (Prague), 2007, 34(1):17-25 | DOI: 10.17221/1847-HORTSCI
The aim of this study was to analyze both the morphological and chemical characteristics of Acorus calamus plants collected from the natural sites in the Czech Republic and to compare them to the sweet flags growing in Finland, Slovenia and Canada, which are concentrated in the Gene Bank collections in Finland. The sweet flags of Finnish, Slovenian and Czech origin were found to be phenotypically and chemically very similar. They all represent the European triploid type of Acorus calamus var. calamus. The average essential oil content was established at the value of 1.50% of dry material in Finland and 1.91% in the Czech...
Storage of sweet cherries in low oxygen and high carbon dioxide atmospheres

Hort. Sci. (Prague), 2007, 34(1):26-34 | DOI: 10.17221/1843-HORTSCI
Acetaldehyde and ethanol are already present in detectable levels at the time of harvest, under aerobic conditions and in healthy, undamaged fruit. Both metabolites can be detected, at different concentrations, in all cultivars. Several hours after harvest, the levels of acetaldehyde in cultivars Summit, Techlovan and Kordia were 6.41, 9.78 and 22.00 mg/l, respectively. Both ethanol and acetaldehyde accumulate to significant levels in anaerobically stored cherries, particularly in atmospheres with high levels of CO2. The highest levels of ethanol observed, after 31 days of exposure to anaerobic conditions, were in the cultivars Techlovan...
Effect of slow release fertilizers on container-grown woody plants
F. Šrámek, M. Dubský
Hort. Sci. (Prague), 2007, 34(1):35-41 | DOI: 10.17221/1844-HORTSCI
Slow-Release Fertilizers (SRF) Silvamix Forte and Silvagen were tested in two-year experiments with container-grown woody plants (Pyracantha coccinea, Thuja occidentalis). Several fertilizing systems were compared: preplant application of SRF into substrate as the sole nutrient source for a two-year period, preplant application of SRF and soluble fertilizer (PG Mix), and preplant application of SRF and soluble fertilizer together with additional fertilizing by solution of nitrogen fertilizer during both growing periods. A system with controlled-release fertilizer (CRF) Osmocote 5-6 was chosen as a control variant; it was incorporated...
Folk landscape architecture as a significant value of Czech landscape
J. Mareček
Hort. Sci. (Prague), 2007, 34(1):42-46 | DOI: 10.17221/1846-HORTSCI
In the past the image of Czech countryside was created by agricultural and social activities of the rural population in a significant manner. These activities related to natural elements and to the creation of landscape in a wider sense can be described as folk landscape architecture. Its object is mainly the spatial arrangement and assortment composition of vegetation and its functionality in villages and in their landscape environment. This study defines these activities as time limited regional (local) customary practices of agricultural and cultural and social character, reflected especially in the spatial arrangement and assortment composition...
