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' were the best. 'Admiral', 'Gold Bohemia' and 'Andera' were the top rated in flesh consistency. 'Admiral', 'Angold' and 'Andera' were the best in juiciness. 'Gold Bohemia', 'Admiral' and 'Meteor' had the highest values of the general taste. 'Admiral', 'Angold' and 'Meteor' were the most attractive.

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 intensified iron chlorosis. Also, contrary to our expectations, the Pyrodwarf/Pyrus communis L. (Dargazi) combination displayed more tolerance to high lime concentrations, whereas the OH × F/Williams Duchesse combination did not exhibit suitable tolerance. As a pear rootstock native to Iran, Dargazi seedling rootstock in combination with different scions was found to have relatively better growth under low lime concentrations, but its response under high lime was not as favourable as expected. Cultivar Dargazi combined with different rootstocks showed a better response to high lime stress compared to other scions, while cultivar Williams Duchesse exhibited lower tolerance to high lime concentration when combined with different pear rootstocks.

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 Tiger F1 with a total carotene contentof 7.1 (green) to 12.5 (half ripen) and 18.6 mg/100g f.w. (in full ripen) and Sacher F1 with vitamin C from 6.2 (green) to 17.2 (half ripen) and 20.7 mg/100g f.w. (in full ripen). This variability can be attributed to these harvesting phases, but also to the genetic factors, such as cultivar type, fruit size and colour.

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 highest fruit yield and growth indexes, whereas not mulched control to the lowest. Fruit dry residue and soluble solids were highest under MB N2/12 and MB N8, titratable acidity was highest under MB N8. Fruits grown under MB N8 and LDPE mulches attained the highest levels of colour components "L" and "b" respectively, and MB N8 the highest fruit firmness. MB N2/12 and MB N8 showed the highest levels of antioxidants and antioxidant activity. Biodegradable polymers improved root growth conditions and fruit quality, showing suitable features for sustainable vegetable production.

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 Holovousy, the Czech Republic. We confirmed the previous S-genotyping for 66 accessions except for Drogans Gelbe, Hedelfinger, Erika, Meckenheimer Frühe, Badeborner, Bing, Alfa, Gamma, Huldra, Rivan, Valerij Tschkalov, Viola and Winkler's Frühe. It could be due to either mislabelling or mistakes in the previous analyses. Newly, S-genotyping was determined for 51 accessions in which we found 4 new S-loci combinations. We detected the S-locus combinations in 19 incompatibility groups. The most frequent incompatibility groups were III (S3S4), II (S1S3), IV (S2S3), and VI (S3S6) with 22, 20, 12 and 12 genotypes, respectively.

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 for moisturizing. 500 g bunches of spears were filled in the bags. Spears were partly covered by the sleeves or totally covered by the bags. All spears were stored for 3 to 11 days at the temperature of 2°C, 8°C and a combination of 2°C/22°C.The last temperatures were to simulate retail conditions. In wet bags spear fresh weight increased, losses in bags with dry fleece were low. Maintaining of fresh weight in wet bags coincided significantly with higher bending firmness, and lower shear force, which points to less fibrousness. Wet storage also reduced the incidence of dried cut surfaces but promoted the incidence of lengthwise fractures and, in combination with higher temperature, grey-brown discolouration and colour saturation. Wet packaging may be beneficial primarily under low temperature and low air humidity storage conditions.
