translocation of nitrogen in the xylem of field-grown cherry and poplar trees during remobilization.studies of small trees growing in pots have established that individual amino acids or amides are translocated in the xylem sap of a range of tree species following bud burst, as a consequence of nitrogen (n) remobilization from storage. this paper reports the first study of n translocation in the xylem of large, deciduous, field-grown trees during n remobilization in the spring. we applied 15n fertilizer to the soil around 10-year-old prunus avium l. and populus trichocharpa torr. & gray ex hoo ...200616414931
combination of antagonistic yeasts with two food additives for control of brown rot caused by monilinia fructicola on sweet cherry fruit.to evaluate beneficial effect of two food additives, ammonium molybdate (nh4-mo) and sodium bicarbonate (nabi), on antagonistic yeasts for control of brown rot caused by monilinia fructicola in sweet cherry fruit under various storage conditions. the mechanisms of action by which food additives enhance the efficacy of antagonistic yeasts were also evaluated.200616478490
natural and recombinant molecules of the cherry allergen pru av 2 show diverse structural and b cell characteristics but similar t cell reactivity.cherry allergy is often reported in the context of allergy to other fruits of the rosaceae family and pollinosis to trees because of cross-reactive allergens. allergic reactions to cherry are reported by 19-29% of birch pollen-allergic patients. pru av 2, identified as a thaumatin-like protein (tlp) from sweet cherry, was recognized by the majority of cherry-allergic patients in immunoblotting.200616499648
cryopreservation of prunus avium l. embryogenic tissues.embryogenic tissues from wild cherry (prunus avium l.) were successfully cryopreserved by using a one-step freezing procedure. cryoprotection consisted of a pretreatment on solid medium with increasing sucrose concentrations (0.25 m for 1 day, 0.5 m for 1 day, 0.75 m for 2 days, and 1.0 m for 3 days), followed by air desiccation to about 20 percent moisture content (fresh weight basis). this method was compared with a pretreatment on solid medium containing 5 percent dmso and 2 percent proline, ...201316547548
a study of ethylene in apple, red raspberry, and cherry.high ethylene levels were associated with flower abscission in apple (malus sylvestris) and cherry (prunus avium and prunus cerasus), "june drop" of immature cherries, and harvest drop of apple and red raspberry (rubus idaeus). however, an increase in ethylene content was not associated with june drop of apples and harvest drop of cherries. during the period of fruit ripening on the plant, the largest increases in ethylene occurred in apple flesh and red raspberry receptacular tissue. ethylene r ...197216658013
the occurrence of nitrate reductase in leaves of prunus species.nitrate reductase was found in leaves of apricot prunus armeniaca, sour cherry p. cerasus, sweet cherry p. avium, and plum p. domestica, but not in peach p. persica, from trees grown in sand culture receiving a nitrate containing nutrient solution. nitrate was found in the leaves of all species. nitrate and nitrate reductase were found in leaves of field-grown apricot, sour cherry, and plum trees. the enzyme-extracting medium contained insoluble polyvinylpyrrolidone, and including dithiothreitol ...197216658037
polyribosomes from aging apple and cherry fruit.the sequence of events which occurs during the ripening of the passe-crassane pear fruit have been previously studied. in this work, we have investigated the ripening of another climacteric fruit (pyrus malus l. cv golden delicious) and of a nonclimacteric fruit (prunus avium l. cv bigarreau napoléon). we show that both climacteric fruits exhibit the same preclimacteric sequence of events. differences exist, however, between the golden delicious apple and the passe-crassane pear in that the prot ...198316663295
development, distribution, and characteristics of intrinsic, nonbacterial ice nuclei in prunus wood.ice nuclei active at approximately -2 degrees c and intrinsic to woody tissues of prunus spp. were shown to have properties distinct from bacterial ice nuclei. soaking 5-centimeter peach stem sections in water for 4 hours lowered the mean ice nucleation temperature to below -4 degrees c, nearly 2 degrees c lower than stems inoculated with ice nucleation-active pseudomonas syringae strain b301d. ice nucleation activity in peach was fully restored by air-drying woody stem sections for a few hours. ...198816666404
bee population returns and cherry yields in an orchard pollinated with osmia lignaria (hymenoptera: megachilidae).during 1998-2003, we used populations of the solitary bee osmia lignaria say to pollinate a commercial sweet cherry orchard in northern utah. bee densities released each year ranged from 1290 to 1857 females/ha, with approximately twice as many males. female progeny produced each year were greater than parental populations released, except in 2003, when nesting was poor due to bird predation. despite poor weather during bloom, and in contrast to most other local producers, the study orchard prod ...200616686139
studies on water transport through the sweet cherry fruit surface. 10. evidence for polar pathways across the exocarp.water uptake through the fruit surface is considered as an important factor in cracking of sweet cherry (prunus avium l.) fruit. uptake may occur by diffusion and/or viscous flow along a polar pathway. to establish the mechanism of water uptake, the effects of viscosity and molecular weight of selected osmotica on water uptake into detached sweet cherry fruit were investigated. in addition we investigated the effect of temperature on penetration of 2-(1-naphthyl)[1-(14)c]acetic acid ([(14)c]naa; ...200616719520
heterozygote excess in a self-incompatible and partially clonal forest tree species -- prunus avium l.wild cherry (prunus avium l.), a partially asexual self-incompatible forest tree, shows heterozygote excess, which is a poorly studied phenomenon. in three natural populations, we found significant heterozygote excess at almost all investigated loci (eight microsatellites and markers for the self-incompatibility locus). we examined four hypotheses to account for this observed heterozygote excess. first, negative f(is) can result from a lack of selfed progeny in small populations of outcrossing s ...200616780428
combined heat and controlled atmosphere quarantine treatments for control of western cherry fruit fly in sweet cherries.nonchemical quarantine treatments, using a combination of short duration high temperatures under low oxygen, elevated carbon dioxide atmospheric environment were developed to control western cherry fruit fly, rhagoletis indifferens curran, in sweet cherries, prunus avium (l.). the two treatments developed use a chamber temperature of 45 degrees c for 45 min and a chamber temperature of 47 degreesd c for 25 min, both under a 1% oxygen, 15% carbon dioxide, -2 degrees c dew point environment. both ...200616813295

studies on water transport through the sweet cherry fruit surface. 11. fecl3 decreases water permeability of polar pathways.the effect of fecl3 (10 mm) on osmotic water uptake into detached sweet cherry fruit (prunus avium l.) and on the (3)h2o permeability (p(d)) of excised exocarp segments (es) or enzymatically isolated cuticular membranes (cm) was investigated. es or cm were mounted in an infinite dose diffusion system, where diffusion is monitored from a dilute donor solution through an interfacing es or cm into a receiver solution under quasi steady-state conditions. in the absence of fecl3, (3)h2o diffusion thr ...200616910722
molecular characterization of three non-functional s-haplotypes in sour cherry (prunus cerasus).tetraploid sour cherry (prunus cerasus) exhibits a genotype-dependent loss of gametophytic self-incompatibility that is caused by the accumulation of non-functional s-haplotypes with disrupted pistil component (stylar-s) and/or pollen component (pollen-s) function. genetic studies using diverse sour cherry germplasm identified non-functional s-haplotypes for which an equivalent wild-type s-haplotype was present in sweet cherry (prunus avium), a diploid progenitor of sour cherry. in all cases, th ...200616915517
comparative analysis of the within-population genetic structure in wild cherry (prunus avium l.) at the self-incompatibility locus and nuclear microsatellites.gametophytic self-incompatibility (si) systems in plants exhibit high polymorphism at the si controlling s-locus because individuals with rare alleles have a higher probability to successfully pollinate other plants than individuals with more frequent alleles. this process, referred to as frequency-dependent selection, is expected to shape number, frequency distribution, and spatial distribution of self-incompatibility alleles in natural populations. we investigated the genetic diversity and the ...200616968267
the mutated s1-haplotype in sour cherry has an altered s-haplotype-specific f-box protein gene.gametophytic self-incompatibility (gsi) is an outcrossing mechanism in flowering plants that is genetically controlled by 2 separate genes located at the highly polymorphic s-locus, termed s-haplotype. this study characterizes a pollen part mutant of the s(1)-haplotype present in sour cherry (rosaceae, prunus cerasus l.) that contributes to the loss of gsi. inheritance of s-haplotypes from reciprocal interspecific crosses between the self-compatible sour cherry cultivar ujfehértói fürtös carryin ...200616985081
self-compatible peach (prunus persica) has mutant versions of the s haplotypes found in self-incompatible prunus species.this study demonstrates that self-compatible (sc) peach has mutant versions of s haplotypes that are present in self-incompatible (si) prunus species. all three peach s haplotypes, s (1), s (2), and s (2m), found in this study encode mutated pollen determinants, sfb, while only s (2m) has a mutation that affects the function of the pistil determinant s-rnase. a cysteine residue in the c5 domain of the s (2m)-rnase is substituted by a tyrosine residue, thereby reducing rnase stability. the peach ...200717006593
detecting local establishment strategies of wild cherry (prunus avium l.).p. avium, a pioneer tree species that colonizes early forest successional stages, is assumed to require an effective strategy allowing stably repeatable rounds of local establishment, dispersal and local extinction. consequently, the early replacement of cherry by climax tree species makes the establishment of several local generations very unlikely, especially in central european continuous cover forests. this has to be seen in connection with the mixed reproduction system involving asexual rep ...200617020607
influence of cultivar and processing on cherry (prunus avium) allergenicity.oral allergy syndrome is an immediate food allergic event that affects lips, mouth, and pharynx, is often triggered by fruits and vegetables, and may be associated with pollinosis. here, we report on the allergenic pattern of different varieties of cherry (prunus avium) and results obtained by applying several technological processes to the selected varieties. whole cherries were submitted to chemical peeling, thermal treatment, and syruping processes, and the relative protein extracts were anal ...200617177523
