Global metabolic profiling of 'Granny Smith' apple peel was employed for evaluating metabolomic alterations resulting from prestorage UV-white light irradiation. Apples were bagged midseason to restrict sunlight, harvested at the preclimacteric stage prior bag removal, treated with fluorescent 0-48.5 h, and stored 6 months 0 degrees C. Trimethylsilyl (oxime) derivatized or underivatized aliquots methanolic extracts samples collected immediately after irradiation following cold storage...
Abstract BACKGROUND: Certain apple cultivars develop a greasy feel when overripe. Treating fruits with the ripening inhibitor 1‐methylcyclopropene (1‐MCP, SmartFresh ™ ) reduces fruit greasiness. This study examines nature of this phenomenon. ‘Royal Gala’ apples were treated 1‐MCP at 1.0 µl L −1 following harvest. Periodically, during storage − 1 °C for up to 6 months, evaluated internal ethylene concentration, epicuticular wax morphology (using scanning electron microscopy) and non‐polar...
ABSTRACT Four rates of ammonium nitrate (NH4NO3) (0, 151, 454, and 908 g actual N/tree) were applied each spring for 6 years to 'Golden Delicious' (Malus domestica) apple trees. High nitrogen (N) increased N concentration Orchardgrass (Dactylis glomerata) blades cover-grass growth whereas various legume species prevalent at the low rates. Leaf in spur or mid-terminal leaves yearly, was related leaf color by visual comparison reflectance. Fruit from higher had greener peel lower firmness,...
ABSTRACT Fire blight of apple and pear is initiated by epiphytic populations Erwinia amylovora on flower stigmas. Predicting this disease managing it with microbial antagonists depends an understanding bacterial colonization Detached 'Manchurian' crab flowers were inoculated E. subjected to a range constant temperatures or various fluctuating temperature regimes. Results may have application risk assessment systems such as the Cougarblight model, which now are based in vitro growth pathogen....
SummarySkin tissue disks from preclimacteric or climacteric apples were incubated on preset temperature plates and exposed to high intensity white light find the optimum of anthocyanin accumulation. Pre-climacteric fruit developed more than did fruit. Different cultivars showed different optima. Pre-cooling for 48 h at 2°C before incubation 25°C increased amount pigment that accumulated. The highly colouring Scarlet Spur 'Delicious' sport a higher rate accumulation, but similar Oregon 'Delicious'.
The stigmatic secretions of pomaceous flowers serve as a natural medium not only for pollen, but also the pathogen Erwinia amylovora (Burr.) Winslow et al. and other microorganisms. To understand microecology on stigma, exudates from cultivars pear ( Pyrus communis L.), apple Malus pumila P. Mill.), crab [ mandshurica (Maxim.) Kom.] were analyzed free sugars amino acids available carbon nitrogen sources. Extracts obtained at different stages anthesis by submerging sonicating stigmas in...
Bruising of apples results in millions dollars loss annually. To reduce economic loss, a greater understanding the mechanisms involved is necessary. Our objective was to visualize damage due bruising, using different methods microscopy, as an aid substantiating which were most viable. 'Golden Delicious' at maturity levels similarly bruised with artificial silicon finger attached Instron machine. induced on freshly harvested fruit and examined after 48 h room temperature. We used fluorescence...
A 2-year study was conducted in a ‘Golden Delicious’ ( Malus × domestica Borkh.) orchard with high incidence of physiological fruit russeting to examine the effect gibberellin 4+7 (GA ) on apple epidermal cell size. Beginning at petal fall, four sequential applications GA (0, 15, or 30 mg·L −1 were applied whole trees every 7–10 days an air-blast sprayer volume ≈1000 L·ha . Fruit tissue samples taken approximately monthly beginning 1 week after fourth application. Tissue treated laboratory...
CPPU was applied to whole spur `Delicious' apple (Malus domestica Borkh.) trees in central Washington at 0,6.25,12.5,25, or 50 mg·liter- 1 full bloom (FB) FB plus 2 weeks. At both application times, the flesh firmness of treated fruit linearly increased with increasing concentration. 0,5,10,15, 20 mg·liter -1 Massachusetts king resulted a linear increase harvest and following 28 weeks air storage 0C. did not affect incidence senescent breakdown, decay, cork spot. Fruit length: diameter (L/D)...
Abstract Paclobutrazol (PP333) is a promising new bioregulant for controlling size of trees and significantly reducing the need dormant summer pruning. ‘Delicious’ were treated with high rate PP333, which resulted in some smaller, flattened fruit shorter pedicels. Application either gibberellin A 4+7 plus 6-benzylamino purine (Promalin) or 3 (GA ) before at full bloom increased size, pedicel length, leaf on PP333-treated trees.
SummaryDevelopment of wax platelets on the surface 'Delicious' (Malus domestica Borkh.) apple fruit was investigated throughout growing season using field emission scanning electron microscopy. At 5,000 and greater, crystalline structures appeared to be composed microtubules (MT), aggregates individual MT form single platelets, one or more platelets. The thickness a platelet ranged from 116–128 nm, approximately diameter MT; whereas multiple-platelet in 307–428 nm. Individual multiple were...
Lovastatin is a specific hydroxymethylglutaryl coenzyme-A reductase inhibitor in animals and as such, potent cholesterol lowering pharmaceutical for human use. Because it has also been shown to inhibit α-farnesene certain plants, we investigated its effects on ethylene biosynthesis, volatile production, fruit color during ripening `Golden Supreme' apples [ Malus sylvestris (L.) Mill. var. domestica (Borkh.) Mansf.]. Immediately after harvest, were dipped solution 2 min, allowed dry, stored...
Lenticel breakdown disorder (LB), most prevalent on ‘Gala’ ( Malus × domestica ) apples, especially in arid regions, has also been observed other common cultivars. Depending the preharvest environment, fruit maturity, and length of storage, LB usually appears as one or more round, darkened pits, centered a lenticel, ranging diameter from 1 to 8 mm. Symptoms are not visible at harvest nor they apparent unprocessed after storage. However, following typical processing packing, symptoms fully...
Abstract Translocation patterns of the triazole plant growth retardants paclobutrazol, triapenthenol, and BAS111 were found to be similar when applied as a trunk paint, soil drench, or in hydroponic systems. Chemical degradation studies indicate that greatest percentage parent compound is translocated roots mature leaves following drench treatments. Generally, residue levels significantly lower than those paclobutrazol triapenthenol. Data from paint applications triapenthenol BAS111, even at...
Preclimacteric `Bartlett' pears ( Pyrus communis L.) were dipped for 3 min in either corn Zea mays or soybean [( Glycine max (L.) Merrill] oil emulsion immediately after harvest and stored at 0 °C. Untreated control fruit developed higher percentages of senescent scald, core breakdown, decay 15 weeks storage. Both treatments inhibited a similar concentration dependent manner. Complete scald breakdown was achieved by emulsions 5% 10%, 10%. Compared with controls, delayed reduced internal...
The domestic apple might well be called an 'extreme' fruit. In the arid Northwest United States, fruit often tolerates surface temperatures ranging from -2 °C in early spring to 50 heat of summer, and again during controlled postharvest storage for up 12 months. During its 18-month existence, maintains a cuticle that is dynamic environmentally responsive protect against 1) cellular water loss desiccation stress 2) excessive uptake standing moisture. Physiological disorders peel such as...
