The aim of this work was to verify a comparative procedure for evaluating apple cultivars based on typology and comparing the sensory features of the examined cultivars during cold storage and simulated shelf-life. The procedure was applied experimentally to compare scab-resistant apples to known commercial cultivars. The procedure consisted of four sensory profiling analyses of internal apple characteristics: after two and four months of cold storage and after an additional ten days of shelf-life following each cold storage period. Eleven sensory attributes were evaluated at each timing, resulting in four general types of apple cultivars indicated...

The results of the investigation of morphogenesis and productivity characteristics of Cucumis sativus parthenocarpic hybrids Marinda and Kurazh in ontogenesis in greenhouses under the thermic films are presented. The thermic films have IR- and UV-shielding properties at the expense of coating with nanoparticles of copper compounds (film TF1) and compounds of silver and copper (film TF2) on the surface of films by magnetron sputtering. It is shown that thermic films contributed to levelling of day and night temperatures. The use of the film TF1 favoured seeds germination, activation of plant growth and development, shortening of period of the...

The study compares the effects of: timer ('Timer') and soil moisture sensor-controlled irrigation on soilless lettuce; two volumetric water content (Θ) thresholds for irrigation (0.30 ('Θ = 0.3') and 0.40 m3/m3 ('Θ = 0.4')). The most nutrient solution (NS) was applied in 'Timer' where the lowest water use efficiency was observed, with 17 and 42% less NS used in 'Θ = 0.4' and 'Θ = 0.3', respectively. Irrigation volumes followed the plant water needs in the sensor-controlled treatments, with little or no leaching, while 18% of leaching was recorded in 'Timer'. Plants in 'Timer' and 'Θ = 0.4' had...

Horticultural industry significantly affects the environment. In particular, large amounts of irrigation water and fertilizers required for intensive plant production can result in an increased nutrient runoff to surface and ground water. The objective of the study was to evaluate the effect of different fertilization strategies on the growth and flowering of container-grown English lavender cv. Dwarf Blue and the composition of the leachates generated by this crop. Three types of controlled-release fertilizers (Osmocote 16-9-12, Plantacote 15-10-15 and Multicote 17-17-17) at three rates (1.5, 3.0 and 4.5 g/l) were compared to fast-acting fertilizers....

Seed germination experiments with Corylopsis coreana, C. sinensis var. calvescens, and Corylopsis gotoana were conducted. Corylopsis coreana seeds were treated at 5o, 7.5o, 10o, 12.5o and 20oC to study the upper temperature limit to break dormancy. Seeds of C. sinensis var. calvescens were treated 1 mo of warm stratification (WS) at 10, 15, 20, and 25oC followed by CS at 5oC for 0, 1, 2, and 3 mo to understand the requirement of WS and CS to effectively break dormancy. Germination of Corylopsis...

The aim of this work is to determine the compatibility, the scion biomass, and the yield of the grapevine variety Welschriesling grafted onto 12 grapevine rootstocks. As an index of compatibility, the callus development and graft success were determined. Dry weight of canes was measured at the end of the growing seasons (2011-2014), while root dry weight only in the first year in the nursery. The grape yield was measured in the first production year. Welschriesling showed good compatibility with all examined rootstocks. More than 85% of grafts had a complete callus development (8BČ rootstock 100%). The average of graft success in the nursery was 67%,...
Molecular cloning and characterization of allele d ‒ a newly identified allele of the 1-aminocyclopropane-1-carboxylate oxidase 1 (ACO1) gene in apple - Short CommunicationShort Communication

Apple is a climacteric fruit of economic importance and high nutritional value. Better understanding of the apple ripening process is needed to improve fruit quality and extend apple shelf life. This paper presents the results of molecular cloning and characterization of a newly identified allele of the ripening-specific ACO1 gene from Malus floribunda 821. A polymorphism of the ACO1 gene was detected using the polymerase chain reaction and BamH1 and RsaI enzymatic digestion. Whilst cloning and sequencing data confirmed the identity of allele d, it also revealed high sequence conservation (97.3...
