Development of prediction models for the quality of apples is useful in guiding fruit tree nutrition and in optimising fruit management. 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...

Results of all public consumer preference testing sessions included in this study were to be divided into 3 time periods. 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...

The effects of several pre- and postharvest factors on apple cv. 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...
Detection and molecular characterization of phytoplasmas infecting apple trees in PolandOriginal Paper

During 2010-2012, samples from 225 apple trees growing in six regions of Poland were tested for phytoplasmas. 16S rRNA gene and 16S-23S spacer region sequences were amplified from total DNAs prepared from phloem tissue of apple shoots. 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...
Effect of root pruning and irrigation regimes on pear tree: growth, yield and yield componentsOriginal Paper

The effect of root pruning (RP) as compared with non-root pruning (NP) and the potential of supplemental irrigation in alleviating the negative effect of root pruning on fruit growth, yield and yield components were investigated in a pear orchard from 2010 to 2011. 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...
Mouldy, musty earthy off-odour of apple fruits - Short communicationOriginal Paper
K. Kaack
Hort. Sci. (Prague), 2014, 41(1):44-47 | DOI: 10.17221/87/2013-HORTSCI
Chemical compounds identification that cause the mouldy, musty and earthy off-odours of apple fruit stored in controlled atmosphere at low temperature for several months has been studied. 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...
