Nitrogen and carbohydrate (soluble sugars and starch) reserves were analysed in twig samples of 'Red Beaut' and 'Showtime' Japanese plum (Prunus salicina Lindl.) cultivars cultivated in two similar experimental orchards under organic and conventional management. 'Red Beaut' is a vigorous cultivar while 'Showtime' is a middle to low vigorous cultivar. Both cultivars exhibited delayed flowering and premature defoliation under organic management. In general, there were no differences in the concentration of reserves between the two types of management for either of the two plum cultivars, and, likewise, no differences were observed between cultivars,...

This research was aimed at assessing the impact of different doses of nutrients on growth and flower quality of the Asiatic hybrid Lilium ((Lilium × elegans Thunb.) cv. 'Fangio') under the soilless culture. Five nutrient (fertigation) regimes were applied (T1: daily, T2: twice a week, T3: weekly, T4: twice a month and T5: control). Increasing the nutrient supply increased chlorophyll content index (SPAD, 45-93%), leaf area (30-55%), number of flowers per plant (25-67%) and substrate electrical conductivity (EC: 28-300%) compared to control. Although T3 (weekly nutrient supply) had lower shoot N, P, K+ and Ca+2...

This study was conducted to study the influence of plant density and irrigation on the content of phenolic compounds, i.e., phenolic acids and flavonols in cv. 'Sevilla' cauliflower curds. Levels of phenolic acids and flavonols were in the range of 3.0-6.2 mg and 25.4-87.8 mg/100 g of dry weight, respectively, depending on plant density and irrigation. Of the phenolic acids, caffeic acid was detected in the highest amount, followed by p-coumaric acid, sinapic acid, gallic acid, and ferulic acid. Of the two flavonols detected, the levels of quercetin were higher than those of kaempferol. The content of the detected phenolic acids (with the...

Hort. Sci. (Prague), 2017, 44(4):186-194 | DOI: 10.17221/266/2015-HORTSCI
This study investigated in vitro production of diploid (AS2) and tetraploid (AS4) cytotypes of snowdrop anemone. The effect of plant growth regulators (PGRs) on in vitro shoot multiplication and rooting was investigated. The effect of activated charcoal (AC) on root induction was also studied. Ploidy level affected growth characteristics during multiplication and rooting. Shoot induction in AS4 was higher on medium supplemented with cytokinin (3.2-3.6), while the AS2 clone formed the most shoots on PGR-free medium (3.6). The highest rooting percentage was achieved on PGR-free medium in both genotypes (AS2 clone, 100% and AS4 clone,...

Agricultural practices, biology and quality of eggplant cultivated in Central Europe. A reviewReview
Gianluca Caruso, Robert Pokluda, Agnieszka Sêkara, Andrzej Kalisz, Ale¹ Jezdinský, Tomá¹ Kopta, Aneta Grabowska
Hort. Sci. (Prague), 2017, 44(4):201-212 | DOI: 10.17221/36/2016-HORTSCI
The eggplant is a warm-climate crop of high economic importance. In many Asian and Mediterranean countries, eggplants are essential components of everyday dishes, while in Central Europe they have become popular only in recent years. Eggplants are harvested at an immature stage and have low storage value; therefore, the sale of fruits in local markets requires an appropriate production strategy. In Poland, consumer demand for eggplants is currently met by imports and domestic production, which, until recently, has been carried out only in greenhouses, ensuring the availability of fresh fruits but resulting in high selling prices. The demand for eggplants...
