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 and the cultivar storability over long cold storage time and shelf-life rated. The study was performed on 8 scab-resistant and 14 commercial apple cultivars evaluated over two consecutive years. The examined cultivars were then segmented into six groups of different sensory characteristics, which allowed for indicating those scab-resistant cultivars which might replace the conventional ones of equivalent sensory features.

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 fruiting beginning and increase in productivity of hybrid Marinda by 13% and hybrid Kurazh by 35%. The use of the film TF2 led to inhibition of growth processes of both hybrids and decrease in their productivity.

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 higher fresh weights (24%) and leaf area (13%) than plants in 'Θ = 0.3'. Similar dry weight was observed among treatments but percentage of dry matter was 20% higher in 'Θ = 0.3'. Gas exchanges and leaf tissues chemical composition were similar in all treatments, but nitrate concentration was lower in the 'Θ = 0.3' plants. Precision sensor-controlled irrigation based on Θ measurements is an effective tool to increase the overall water use efficiency and to improve the quality of soilless-grown lettuce by acting on the substrate moisture level.

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. The application of Multicote promoted vegetative growth of lavender but inhibited the appearance of flower spikes. Plants fertilized with Osmocote and Plantacote at the highest rate produced the highest fresh weight and the highest number of flowering spikes, as well as the best quality. However, these rates gave relatively high values of nitrogen nitrate content after 4 weeks of plant cultivation. Among the applied controlled-release fertilizers, Multicote had the lowest potential to contribute nitrate pollutants discharged from containers.

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 seeds at 15o-20oC without CS suggests that dormancy is considered shallow and the upper temperature limit to break is 12.5oC. Immersing seeds in water or ethanol induced seed germination which may result from leaching of inhibitors from the seed. Observation of seed coats following treatment with water and ethanol by means of low temperature scanning electron microscopy (LT-SEM) revealed elongated and rectangular/hexagonal shaped cells in C. coreana and irregular jigsaw puzzle-piece shapes in C. gotoana. In conclusion, dormancy in Corylopsis is considered shallow and the optimum CS is suggested to be 7.5oC, while optimum WS is ranging from12.5o to 20oC.

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%, but the average of 5BB, G251, and G103 was above 80%. The G103 rootstock had the highest root dry weight after one season. The dry weight of canes in vineyards was above the average with 5BB, SO4, Binova, Börner, and M V rootstocks. All Georgikon rootstocks had a lower cane dry weight per vine than the others. The highest yields were recorded on SO4, G251, and Börner rootstocks.

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 to 98.9%). In addition, a comparison of sequence data revealed some differences within the coding regions of the ACO1 alleles identified so far.
