The interrelationships between the leaf nutrient contents and some fruit quality indices were studied in five apple cultivars - Generos, Florina, Delicios de Voinesti, Jonathan and Pionier. Highly significant relationships between N and Fe contents (R2 = 0.734; P < 0.01) and between Cu and K (R2 = 0.702; P < 0.01) were found. Acidity was negatively correlated with soluble solids content in the cvs Generos, Delicios de Voinesti and Jonathan, whereas the respective correlation in the apple cv. Pionier was positive. In cv. Florina fruits no significant correlation was found between acidity and soluble solids content. Among macroelements, nitrogen had a considerable contribution to fruit acidity and this allows to predict this index with a high degree of safety (R2 = 0.690; RMSEPN = 0.105). Microelements have a lower contribution to acidity and a higher one to the sugar accumulation; in case of Zn are R2 = 0.809; RMSEPZn = 4.250.

During the oldest period (1979-1990), with regard to overall qualities and appearance of fruits, the cv. Rubín was the most preferred. Next, it was followed by the cvs Fantazie, McIntosh, Gloster, and Melrose. In the subsequent period (1991-2001), the cv. Bohemia was in the first position in all respects including taste and fruit appearance. Following it in downward sequence were the cvs Rubín, King Jonagold, Jonagold, McIntosh and Melrose. In the latest period (2002-2013), again both in the total scoring and fruit appearance, Bohemia was the most preferred. It was followed in descending order by cvs Orion, Meteor, Jomured, HL 623 and Gold Bohemia. Considering fruit taste alone, however, the most preferred cultivar was Orion. According to the overall results of studies from thirty-three years, in which a total of 198 cultivars or genotypes were included, the most preferred was cv. Bohemia, followed by cvs Meteor, Rubín, HL 623, Andera, Gold Bohemia, King Jonagold and Jomured. Regarding fruit taste itself, the top cv. Bohemia was directly followed by cv. Gold Bohemia and by the selection HL 1834.

Braeburn browning disorder (BBD) incidence using a nine-factor experimental design has been investigated. The design allowed the determination of the effects of single factors as well as their interaction with growing season and storage time. BBD increased in severity with storage duration. BBD incidence was reduced with calcium and potassium fertilizers application, while it was increased when triazoles were used. Delayed controlled atmosphere (DCA) application resulted in less BBD in storage, while treatment with 1-methylcyclopropene (1-MCP) increased BBD incidence. More BBD was observed in fruit stored at above optimal CO2 levels. BBD incidence was increased when O2 concentration in CA was increased from 1 kPa to 3 kPa (optimum CA) or 6 kPa. Finally, the various factors showed a different effect for different growing seasons and storage time. These findings suggest a possible mechanism for the development of BBD. Further work should focus on extending the experimental design to include the interactions between the different pre- and postharvest factors.

According to the results of PCR-RFLP and sequence analyses, apple trees were infected by Candidatus Phytoplasma mali and Ca. P. asteris. Fragments of 16S rDNA plus 16S-23S spacer region of the Ca. P. mali isolates digested with HpaII enzyme showed two restriction profiles: P-I and P-II. Multiple alignments of 16S rRNA gene fragments revealed that the isolates of Ca. P. mali shared 100% sequence identity among themselves as well as with reference strains AT and AP-15 of apple proliferation phytoplasma. The nucleotide sequence of the same region of Ca. P. asteris isolates confirmed the phylogenetic relationship with reference strains OAY (MIAY) and AY1 of aster yellows phytoplasma PCR-RFLP analysis of ribosomal protein (rpl22 and rpS3), secY, and tuf genes did not show the sequence diversity of the isolates of aster yellows phytoplasma.

Results showed that the total shoot length and the number of shoots per tree decreased by 72% and 43%, respectively, in the RP compared to the NP trees; however lateral root growth was stimulated by the RP treatment in the upper soil layers (30-40 cm). Full irrigation and deficit irrigation treatments stabilized the return bloom and improved fruit yield and size compared with the non-irrigated treatment without stimulating vegetative growth. Conclusively, the results indicate that root pruning is an effective practice controlling excessive shoot growth, and supplemental irrigation can improve fruit yield and quality in the root pruned trees. Therefore, a combination of root pruning and irrigation could be a promising alternative to control tree size and secure a stable fruit yield in pear orchards.

Compounds with off-odour were extracted from cv. Golden Delicious apple peel using ether and purified on a silica-aluminium column with washing using a sodium carbonate solution. Presence of compounds with mouldy, musty and earthy off-odour in extracts and washings was verified using a sensory panel with four members intensively trained in identification and description of the odour throughout the whole analytical process. Separation of compounds in the final extract by gas chromatography showed that the odour was associated with five peaks associated with oxidation products of α-farnesene.
