The results from 23 tasting sessions of experienced evaluators that took place during the last decade in May are presented in 4 periods which lasted 5 years except for the first one, which was seven-years long. The winner of the first testing period was 'Bohemia', 'Meteor' was the winner of the second period and 'Admiral' was the top rated in the remaining two testing periods. Across all the years, 'Meteor' had the highest total punctual value, but it was only about 0.4 points higher than 'Admiral'. In the next sequence, they were followed by the cultivars 'Andera', 'Rubin' and 'Andego'. In the aroma evaluation, 'Andera', 'Gold Bohemia' and 'Topaz'...

The aim of the research was the determination of the tolerance of different pear grafting combinations to various levels o lime concentration in calcareous soils. The experiment was carried out under pot conditions for a two-year period (2015-2016). Two factors including combination of rootstocks/scions (3 × 3) and levels of lime concentration were employed to evaluate leaf responses including total iron (Fe), available Fe, chlorophyll (Chl) (a, b, total), and chlorophyll fluorescence attributes (F0, Fm, Fv/Fm) as well as annual growth and internode length of current shoots. Results showed that soil lime significantly reduced tree growth but conversely...

The main purpose of this study was to highlight the nutraceutical value of the tomato fruit for five hybrids recently introduced in culture, during the harvesting phases: mature green, half ripen and full ripen: 'Antalya', 'Cemil', 'Lorely', 'Tiger' and 'Sacher'. They differentiate because of their size and fruit colour. The parameters to be followed for each harvest phase were: the chlorophyll a and b content, the total carotenes, the soluble substance, vitamin C, the titratable acidity, and also a maturity index was established. The results obtained showed significant differences between the hybrids, but also during the maturation phases. It singularised...

Research in southern Italy assessed the effects of biodegradable mulch on fruit yield and quality of two greenhouse tomato cultivars, 'Coronel F1' and 'Kero F1'. Three mulching types (two MaterBi biodegradable black films, MB N2/12 amnd MB N8; black polyethylene film, low-density polyethylene (LDPE)) and not mulched control were compared. 'Coronel F1' showed higher values of fruit yield, total crop biomass and leaf area index (LAI). MB N8 and LDPE films led to the...

Sweet cherries are self-incompatible, which is determined by a gametophytic self-incompatibility system (GSI). The self-incompatibility is controlled by a multi-allelic S-locus. Knowledge about the S-allele constitution of the cultivars is essential for fruit growers and breeders. Recently, molecular PCR-based methods have been developed to distinguish all S-alleles in sweet cherries. In our work, we analysed S-locus genotypes by 13 universal and allele-specific PCR primer combinations within 117 registered, old and local sweet cherry cultivars from the Czech genetic resources of the Research and Breeding Institute of Pomology in...
In-package moisture supports quality maintenance of white asparagusOriginal Paper

White asparagus is a highly appreciated, high-value crop with a distinguished economic relevance among vegetables. Freshly harvested asparagus is available only during a short part of the year and the demand varies. The produce is perishable and only proper handling can ensure its quality after a reasonable shelf life. In this study, we investigated a new method to reduce one of the most important reasons for quality decline: fresh matter losses. The potential benefits or disadvantages of moist asparagus packaging for unpeeled white asparagus (cv. 'Gijnlim') was tested. We used polythene sleeves or bags, lined with cellulose fleece to hold added water...
