Plant-specific NAC transcription factors (TFs) play crucial roles in various pathways related to the stress response. However, to date, little information regarding NAC gene regulation during fruit ripening is available for the apple (Malus domestica). Here, we report that 13 out of 182 MdNAC genes were differentially expressed during the stages of fruit growth and ripening. Sequence analysis indicates that these 13 MdNAC genes harbour distinct structures and potentially diverse functions. The expression of both MdNAC1a and MdNAC78 was repressed by ethylene and induced by 1-MCP during storage. MdNAC2,...

Hort. Sci. (Prague), 2018, 45(1):11-17 | DOI: 10.17221/31/2017-HORTSCI  

Fifteen apple cultivars registered in the Czech Republic were included in this comparative study. The most productive after eight years of cropping was 'Rucla', which had a mean yield of 50.9 t/ha. This cultivar was also the most tolerant to late spring frosts. In order of decreasing yields, it was followed by the cultivars 'Rubinstep', 'King Jonagold' and '©ampion'. The lowest yield was found for the cultivar 'Fuji Nagafu' (23.7 t/ha) followed by 'Golden Delicious' and 'Rubinola'. The largest canopy volume in 2016 was achieved by 'Rubín' at a level of 2.74 m3, followed in decreasing order by 'Rubinola', 'King Jonagold' and 'Meteor'. According...

Hort. Sci. (Prague), 2018, 45(1):18-21 | DOI: 10.17221/23/2017-HORTSCI  

This study was conducted in the period 2010-2015 to assess the influence of rootstocks on the growth and fruiting of apple trees of the 'Golden Delicious Reinders' cultivar. The experiment was conducted in an experimental orchard in D±browice, Poland. The experimental material consisted of the Polish rootstocks P 66, P 67, P 68 and P 16, and the following American rootstocks of the Cornell Geneva series resistant to fire blight: CG.11, CG.41, CG.013 and CG.202. The rootstocks M.9T337, M.26, P 14 and P 60 were used as the control combination. The best-yielding trees were those from the CG.11 rootstock, while those from P 14 and P 67 were the lowest-yielding....

Hort. Sci. (Prague), 2018, 45(1):22-28 | DOI: 10.17221/17/2017-HORTSCI  

The aim of this study was to examine the impact of different liquid fertilisers on selected physiological parameters in order to evaluate the drought tolerance of cherry tomato seedlings. The following physiological parameters were investigated: total phenolic and flavonoid content, total antioxidant capacity and proline content of leaf extracts. Total phenolic and flavonoid content were determined using the Folin-Ciocalteu and aluminium chloride colorimetric methods, respectively. The ferric-reducing/antioxidant power (FRAP assay) was used to measure the total antioxidant capacity, while proline content was evaluated according to the method of Bates....

Preliminary evaluation of day-neutral strawberry cultivars cultivated in Italy using a qualitative integrated approachOriginal Paper

Hort. Sci. (Prague), 2018, 45(1):29-36 | DOI: 10.17221/106/2016-HORTSCI  

In this study the texture profile, total soluble solids (TSS) and the fruit skin colour of four day-neutral strawberry cultivars cultivated in Italy ('Anabelle', 'Murano*', 'Portola*' and 'Triumph') was evaluated at four harvest times. The interrelationships of the analysed parameters were determined using principal component analysis in order to suggest the best commercial scenario (local market, supermarket retailer or export) for each cultivar. Data analysis related to texture and TSS contents revealed that 'Anabelle', 'Portola*' and 'Murano*' displayed unique characteristics, and that 'Triumph' showed lower values for these parameters. Due to its...

First characterisation of minor and neglected Vitis vinifera L. cultivars from Mount EtnaOriginal Paper

Hort. Sci. (Prague), 2018, 45(1):37-46 | DOI: 10.17221/198/2016-HORTSCI  

Eight minor and neglected cultivars of Vitis vinifera L. were characterised according to their ampelographic and agronomic traits and discriminated by molecular analysis with SSR markers. These results are the first complete ampelographic description of these minor and neglected cultivars from the Mount Etna region. The results of this study reveal high morphological diversity of ancient grapevines growing in this region. SSR markers enabled us to discriminate the cultivars and revealed the genetic divergence between them and several autochthonous cultivars. Our efforts could contribute to a better knowledge of grape biodiversity based on...

Seasonal variation of ascorbic acid and nitrate levels in selected basil (Ocimum basilicum L.) varietiesOriginal Paper

Andrea Muráriková, Jarmila Neugebauerová

Hort. Sci. (Prague), 2018, 45(1):47-52 | DOI: 10.17221/216/2016-HORTSCI  

The aim of this study was to determine the levels of ascorbic acid and total nitrates in the fresh aerial parts of different varieties of basil (Ocimum basilicum L.) in different growing seasons. The ascorbate-nitrate index (IAN) is used to determine the safety of basil for consumers. Seven basil varieties ('Ohøe', 'Lettuce Leaf', 'Purple Opaal', 'Dark Green', 'Mammolo Genovese', 'Mánes' and 'Red Rubin') were cultivated as pot cultures in greenhouses during the period 2015-2016. High-performance liquid chromatography (HPLC) was used to determine the ascorbic acid content, which ranged from 34.3 to 222.0 mg/kg f. w. An ion-selective...
