Genetic diversity and genetic relationships of Czech apple cultivars were evaluated. Trees of 33 Czech apple cultivars and 97 reference foreign cultivars were analysed using the set of 10 SSR (simple sequence repeat) primer pairs. The total of 89 polymorphic alleles were amplified, while the number of alleles per locus ranged from 4 to 14. The SSR dendrogram, based on the Jaccard's similarity coefficient, divided apple cultivars into three major groups: Cox's Orange Pippin, McIntosh and Golden Delicious ancestries. The clustering highly depended on pedigree and origin of apple cultivars. Spontaneous mutated cultivars were identical with their progenitors....

The effects of five training systems on tree growth, fruit yield and some fruit characteristics were assessed in Jonagold apple cv. grafted on M.9 rootstock. The trees were trained in one of five ways: slender spindle (SS; 4,761 trees/ha), vertical axis (VA; 2,857 trees/ha), hytec (HT; 1,904 tree/ha) and two different tree densities of super spindle (L-Super S with 5,000 trees/ha; H-Super S with 10,000 trees/ha). Trunk cross-sectional area (TCA) was higher in HT and VA than SS, L-Super S and H-Super S in the 4th year. While HT had the highest cumulative yield/tree, the lowest cumulative yield was observed in H-Super S. Although HT had the...

The pigmentation response, coloration components and the metal elemental content of Yunnan Red Pear were studied. Light is indispensable for peel pigmentation. With increasing duration of illumination of fruit, the area of skin colour and colour intensity of peel increases due to accumulation of anthocyanin. The red anthocyanin component of Yunnan Red Pear skin is cyanidin-3-O-galactoside. Other phenolic compounds in pear skin are chlorogenic acid, isorhamnetin-3-O-galactoside and isorhamnetin-3-O-6"-malonylgalactoside; or isorhamnetin-3-O-6"-malonylglucoside; or isorhamnetin-3-O-malonylgalactoside. The...
Effect of low oxygen and high carbon dioxide atmospheres on the formation of volatiles during storage of two sweet cherry cultivars

Hort. Sci. (Prague), 2012, 39(4):172-180 | DOI: 10.17221/165/2011-HORTSCI
The aroma profiles of two sweet cherry cultivars Kordia and Vanda were investigated during storage at different oxygen and carbon dioxide levels and at a low temperature using solid phase microextraction gas chromatography combined with mass spectrometry (SPME-GC-MS). The most abundant aroma volatiles observed in both sweet cherry cultivars were alcohols, esters, terpenoids and aldehydes. Fifteen alcohols (but principally ethan-1-ol, (E)-2-hexen-1-ol and phenethyl alcohol) provided approximately 39% of the total volatile production and eight esters (principally (E)-2-hexenyl acetate and pentyl butyrate) were responsible for another...
Impact of pruning time on tree vigour and productivity of three sweet cherry cultivars grown on two semi-dwarf rootstocks

Tree pruning in two different terms (March and August) was applied in a sweet cherry orchard of Kordia, Těchlovan and Vanda cv. planted on Colt and P-HL-A rootstocks established in 1996 in the spacing 6 × 1.5 m. Tree vigour, yields and mean fruit weight were evaluated in this study in relation to the term of the pruning. The subject of this paper is the experimental orchard in the stage of full productivity and the study is a continuation of a previous publication focussed on its performance till 2005. The vigour of Kordia cv. trees on both rootstocks pruned in August was distinctly weaker. Trees of Těchlovan cv. on P-HL-A grew significantly stronger...
The effect of salinity and high boron on growth, photosynthetic activity and mineral contents of two ornamental shrubs

Hort. Sci. (Prague), 2012, 39(4):188-194 | DOI: 10.17221/167/2011-HORTSCI
Simultaneous salinity and boron (B) excess often occur due to irrigation with water containing high levels of salts, including B. The effects of excess of NaCl and B in the nutrient solution on some agronomical and physiological parameters of Viburnum tinus (laurustinus) and Metrosideros excelsa (metrosideros) were studied. Potted plants were grown in a factorial combination of B (1 and 6 mg/l) and NaCl (2 and 6 dS/m). B toxicity (6 mg/l) caused tip/edge burn in the lower leaves of laurustinus, while these symptoms were absent in metrosideros. Toxicity by B reduced dry biomass in the two species, particularly the aerial part in metrosideros...
Aminoethoxyvinylglycine (AVG) affects cv. Royal Gala apple fruit quality at harvest and after storage - Short communication

Hort. Sci. (Prague), 2012, 39(4):195-198 | DOI: 10.17221/225/2011-HORTSCI
Aminoethoxyvinylglycine (AVG), an inhibitor of ethylene synthesis was applied at a concentration of 125 g/l of active ingredient on Royal Gala apple trees 4 weeks before the anticipated harvest in two consecutive years. Immediately after harvest fruits were stored at 1°C and 90% of relative humidity for up to 90 days. Quality assessments of total soluble solids (TSS), titratable acidity (TA) and firmness were done on 30-days intervals after harvest. Treating Royal Gala apples with AVG significantly slowed down starch degradation in fruits but in the same time increased fruit weight. Also, the development of over colour was negatively affected. A positive...
