'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, regardless of their vigor. Additionally, reserves were also analysed in plantlets of 'Mariana 2624' rootstock (Prunus cerasifera Ehrh × Prunus munsoniana W. Wight & Hedrick) grown in a growth chamber that simulated conditions of spring and autumn periods and subjected to organic or mineral fertilisation. Plants subjected to organic fertilisation were smaller and defoliated earlier, but the sizes of carbohydrate and nitrogen reserves were similar to that of plants grown with mineral fertilisation.

'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 concentrations than T1, this regimen increased the number of flower buds by 20% and flower longevity by 56% compared to T1. Overall, weekly nutrient application is effective at maintaining flower quality and yield in the 'Fangio' lily, and compares favourably with programs in which fertigation is more frequent and the level of total applied nutrients is higher.

'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 exception of ferulic acid) and both flavonols increased with increasing plant density. Furthermore, the concentration of phenolic compounds (with the exception of ferulic acid) was significantly higher under irrigation.

Abstract: 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, 93.3%). The addition of AC to the PGR media largely increased root induction and root length. Rooted plantlets were successfully acclimatised in the greenhouse with 100% survival. Thus, the described micropropagation protocol represents a rapid and effective in vitro propagation method for utilisation in horticulture and conservation programmes of snowdrop anemone.

This research aimed to assess the influence of gibberellic acid (GA3) concentrations and number of applications on the table grape cultivar 'Einset Seedless'. The objective was to evaluate the yield and quality after one, two, or three spray applications of GA3 (7, 14 and 21 days after full bloom) at 100, 200 and 300 mg/l. Unsprayed vines constituted the control. GA3 increased yield per vine, cluster weight, and berry weight. Vines sprayed three times had higher yields than treatments performed once or twice. Similar responses were determined for cluster weight and berry weight. Generally, treatments had beneficial effects on cluster length and width. This three-year study, on average, did not indicate impacts of either concentration or number of GA3 applications on cluster and berry number and shape as well as fruit soluble solids Journal: Horticultural Science Pages: 195-200 Volume: 44 Issue: 4 Year: 2017 DOI: 10.17221/51/2015-HORTSCI File-URL: http://hortsci.agriculturejournals.cz/doi/10.17221/51/2015-HORTSCI.html File-Format: text/html X-File-Ref: http://agriculturejournals.cz/RePEc/caa/references/hor-201704-0005.txt Handle: RePEc:caa:jnlhor:v:44:y:2017:i:4:id:51-2015-HORTSCI Template-Type: ReDIF-Article 1.0 Author-Name: Gianluca Caruso Author-Workplace-Name: Department of Agricultural Sciences, University of Naples "Federico II", Italy Author-Name: Robert Pokluda Author-Workplace-Name: Department of Vegetable Growing and Floriculture, Mendel University in Brno, Czech Republic Author-Name: Agnieszka Sękara Author-Workplace-Name: Department of Vegetable and Medicinal Plants, University of Agriculture in Krakow, Poland Author-Name: Andrzej Kalisz Author-Workplace-Name: Department of Vegetable and Medicinal Plants, University of Agriculture in Krakow, Poland Author-Name: Aleš Jezdinský Author-Workplace-Name: Department of Vegetable Growing and Floriculture, Mendel University in Brno, Czech Republic Author-Name: Tomáš Kopta Author-Workplace-Name: Department of Vegetable Growing and Floriculture, Mendel University in Brno, Czech Republic Author-Name: Aneta Grabowska Author-Workplace-Name: Department of Vegetable and Medicinal Plants, University of Agriculture in Krakow, Poland Title: Agricultural practices, biology and quality of eggplant cultivated in Central Europe. A review Abstract: 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 is growing among Polish consumers, and, accordingly, field production is expected to gradually gain in importance due to the fruit's profitability. Accordingly, the biology and farming practices of this warm-climate crop remain in the investigation phase in temperate climate. This review aims to report the status of current knowledge regarding the technologies affecting the biology, cultivation, and nutritional value of eggplant grown in temperate climatic zone.
