The surface of peach (Prunus persica 'Calrico') is covered by a dense indumentum, which may serve various protective purposes. With the aim relating structure to function, chemical composition, morphology, and hydrophobicity skin was assessed as model for pubescent plant surface. Distinct physicochemical features were observed trichomes versus isolated cuticles. Peach cuticles composed 53% cutan, 27% waxes, 23% cutin, 1% hydroxycinnamic acid derivatives (mainly ferulic p-coumaric acids)....
The polyphenolic profile and antioxidant activity of peel, pomace, juice 'Verde Doncella', a Spanish apple cultivar, is presented. Phenolic the worldwide cultivated 'Red Delicious' cultivar was used for comparison. Flavanols, hydroxycinamic acids, flavonols, phloridzin, procyanidin B2, gallic acid were quantified by HPLC. Larger concentrations polyphenolics found in which agreement with total phenolic content (FRAP) values. Doncella' expressed lower flavanols quercetin derivates when...
ABSTRACT During 2004 and 2006, experiments were conducted that measured the absorption of calcium (Ca) by fruit assessed effects Ca sprays on skin flesh apples. Frequent (1 spray/month for 2 or 4 months) treatments increased concentration in skin, but not fruit, several needed to promote a prolonged increase skin. Calcium did influence concentrations magnesium (Mg) potassium (K). Foliar analyses confirmed topical apple tree following as leaves increased.
Abstract The effect of iron deficiency on the amount photosynthetic pigments per unit leaf area was investigated into two fruit tree species, apricot and pear, grown in field. Iron reduced all pigments, but extent reduction depended particular pigment affected. concentration lutein least affected by deficiency. When compared to green leaves, deficient leaves which had lost about 85 percent their chlorophyll a other conserved 30 Tper area). relationships between neoxanthin a, β‐carotene were...
SummaryProhexadione-Ca (ProCa) has been evaluated as a growth inhibitor in the vigorous red apple cultivars 'Fuji' and 'Royal Gala'. Greatest inhibition of shoot was obtained when ProCa first sprayed at about 200 mg l–1 from full bloom (FB) up to 12 d after (DAFB). Shoot regrowth often occured later growing season, second application then needed maintain inhibition. Inhibition due mainly reduction internode length. No effects on yield have found, except for cv. Gala', where an increase...
SummaryVariations of crop-load in the peach (Prunus persica (L.) Batsch.) cv. Catherine by thinning fruitlets at petal fall affected fruit and vegetative growth trees. Shoot length, fresh dry weight decreased exponentially as cropping level increased, while relative increment trunk girth linearly. Yield increased following a quadratic pattern, size, measured mean weight, crop load increased. Mineral element analysis leaves has shown that Mn concentration linearly with increasing numbers...

Abstract BACKGROUND: A strategy to supply Ca directly fruits as a tool for improving peach quality has been devised and tested under field conditions. Since peaches in the area of study (Calanda, Spain) are routinely bagged shortly after thinning, method based on application gels fruit surface was introduced. The effect treatments assessed terms quality, nutrient balance deposition. RESULTS: Application Ca‐containing formulations increased mesocarp exocarp concentrations, providing evidence...
Abstract Experiments to evaluate the effect of in‐season calcium (Ca) sprays on late‐season peach ( Prunus persica L. Batsch cv. Calrico) were carried out for a 2‐year period. Calcium formulations (0.5% and 1.0% in 2008 only 0.5% tested 2009) supplied either as CaCl 2 or Ca propionate combination with two three adjuvants (0.05% nonionic surfactants Tween 20 Break Thru, carboxymethylcellulose, CMC) sprayed four five times over growing season. Peach mesocarp endocarp concentrations determined...
In this work, near infrared spectroscopy (NIR) and an acoustic measure (AWETA) (two non-destructive methods) were applied in Prunus persica fruit 'Calrico' (n = 260) to predict Magness-Taylor (MT) firmness.Separate combined use of these measures was evaluated compared using partial least squares (PLS) support vector machine (LS-SVM) regression methods. Also, a mutual-information-based variable selection method, seeking find the most significant variables produce optimal accuracy models,...
The greatest sensitivity in the determination of lead by hydride generation-direct flame AAS is obtained presence ammonium persulphate (0.012 µg). A complete interference study reported, comparing results when hydrogen peroxide and are employed. oxidation to a metastable tetravalent state prior action oxidising agent considered be mechanism which atomic-absorption signal increased.
The effect of subjecting 'Golden Reinders' apples to a low O(2) pre-treatment (LOT; 1-2% O(2)) was evaluated as strategy decrease the rate bitter pit (BP) incidence after standard cold storage (ST). Immediately harvest, were stored for 10 days at 20 degrees C under O(2). Thereafter, cold-stored (0-4 C) 4 months and changes monitored in terms BP incidence, fruit quality traits mineral element concentrations.After storage, LOT presented 2.6-fold (14%) versus values obtained fruits (37%...
SummaryTwo different spray programmes for split application of prohexadione-calcium (ProCa) were tested on 'Royal Gala' and 'Fuji' apple trees (Malus domestica Borkh.) to evaluate their effect red colour development in the fruit. Applications ProCa into two sprays at full-bloom 60 d after (DAFB) sufficient control shoot growth these cultivars. A third (95 DAFB) did not result any additional beneficial effects. In addition obtaining significant reductions elongation, leaf area also noted. No...
Bitter pit is a physiological disorder of apple fruits apparently caused by localized calcium deficiency or imbalance in associated with low levels the flesh. A new, highly selective method using glyoxal bis(2-hydroxyanil, GBHA) was tested to reveal presence within fruit as red stain. Water-soluble and insoluble analyzed capillary electrophoresis atomic absorption spectroscopy pitted regions, adjacent sound areas pulp from apples. Both methods, staining mineral analysis, showed that...
The influence of rootstock on the mineral composition scion leaves fruit trees is generally accepted.The present work was carried out to corroborate if this also evident for nutrient concentrations in flowers.The study made an experimental orchard sweet cherry (Prunus avium, L. cv.'Van') grafted three rootstocks: Adara, SL 64 and Cok.Flowers were sampled at full bloom 60 days after fuil (DAFB) respectively.They analyzed nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium...
