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. We proved that microsatellite markers were useful for evaluation of genetic resources, collection management and cultivar identification.

Jonagold apple on M.9 in five tree training systems Abstract: 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 highest yield/ tree, it ranked the last in cumulative yield efficiency (CYE) due to high TCA. The highest (CYE) was measured in trees trained as L-Super S. When cumulative yields (CY)/ha were evaluated, the yield advantage of high density planting was clearly evident for the first three cropping years. H-Super S systems (10,000 trees/ha) had the highest CY/ha and achieved a yield of 91.24 t/ha in year 4. HT (1,904 trees/ha) had the lowest CY/ha (33.46 t). Training systems had no consistent effect on average fruit diameter, weight, firmness, soluble solid and titratable acidity.

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 elements Ca, Mg and Fe are abundant in Yunnan Red Pear flesh, and Zn, Mn, Cu were also identified. These results will aid red pear breeding and pear nutrition research, as well as increase understanding of the regulatory mechanisms underlying pear fruit colouration.

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 39% of the volatile production. Four terpenoids (principally limonene and α-linalool) were responsible for a further 15% of volatile production, and 10 aldehydes (principally (E)-2-hexenal and (E)-2-octen-1-al) were responsible for the remaining 7% of total volatile production. However, out of all the volatile compounds detected, a total of just 6 compounds (phenethyl alcohol, (E)-2-hexenal, (E)-2-octen-1-al, pentyl butyrate, (E)-2-hexenyl acetate and limonene) made up 80% of the total volatile production. Fruit stems remained green during all 54 days of the storage period, although one tenth of the stems slowly dessicated in each of the three controlled atmospheres. This is in marked contrast to the stems of fruit held in a regular atmosphere, which turned completely brown.

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 after pruning in August, whereas in the case of Vanda cv. this effect was found on the Colt rootstock. In comparison to the results from the first period of the study when specific productivity was mostly higher after tree pruning done in August, it is in the subsequent stage generally better to prune in the spring time. This change of tree response is evidently connected to a rate of tree ageing and the spring term of pruning probably compensates this development.

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 and the roots in laurustinus. Metrosideros accumulated a similar content of B in all leaves, while the laurustinus tended to accumulate more B in the lower leaves. The leaf B content in laurustinus was reduced by salinity to a greater extent than in metrosideros; however, this was not sufficient to prevent injuries to the laurustinus photosynthetic system.

Royal Gala apple fruit quality at harvest and after storage - Short communication Abstract: 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 influence on fruits' firmness was also evident, while there was no influence of AVG on TSS and TA.
