Abstract:
ABSTRACTCalcium increases postharvest conservation of apples. Consequently, several calcium foliar sprays are generally applied to apple trees. Due to the low mobility of calcium in the phloem, foliar sprays may have low efficiency to supply calcium in the fruits. This study aimed to evaluate the efficiency of different sources of calcium applied to the soil, compared to the foliar application, on the content of calcium in the soil, leaves and fruits, on yield and fruit quality of ‘Fuji’ apple trees. The following treatments were tested: control, soil application of calcium chloride, gypsum, Nitrabor®, hydrated lime and pulp sludge, and foliar application of calcium chloride. For all sources in the soil, 80 kg of calcium ha-1 year-1 were applied. For the foliar treatment, ten sprays with 0.4 % of calcium chloride were performed. The experiment was conducted in two seasons (2008/2009 and 2009/2010), in a complete randomized blocks design, with four replicates and two apple trees per plot. Even in a soil with high calcium content, the sources of calcium increase the calcium content in the soil and leaves, as well as the firmness of apples stored for 90 days. The use of gypsum and pulp sludge increase the calcium content in the flesh of ‘Fuji’ apples after two successive applications (2009/2010). The sources of calcium applied to the soil can replace the leaf application commonly used in apple orchards, in order to reduce production costs, provided there is no water restriction in the orchard.

Abstract:
The aim of the study was to examine the effect of calcium chloride (CaCl<sub>2<sub>) spraying at different rates of water on apple (<em>Malus domestica</em> Borkh.) calcium concentration. The examination was carried out in 1997-1998 on 'Jonagold' apple trees grafted on M.26 rootstock and planted in 1990 on sandy-loam soil at a distance of 4 x 2.5 m.The trees were trained as a spindle at 2,4 m and 2 m of height and canopy width, respectively. In the experiment apple trees were sprayed with CaCl<sub>2<sub> at a rate of 7 kg ha<sup>-1<sup> using 250, 500, 1000 and 1500 L of water volumes which gives : 2.8, 1,4, 0,7 and 0.5% CaCl<sub>2<sub> solutions, respectively. Sprays with CaCl<sub>2<sub> solutions were applied 6, 4 and 2 weeks before commercial fruit harvest. The trees unsprayed with Ca served as a control. The study showed that sprays with CaCl<sub>2<sub> at all studied water volumes had not effect on leaf and fruit damages. Regardless of the applied water rates, apples from the middle and the bottom of the canopy had higher calcium concentrations as a result of CaCl<sub>2<sub> sprays whereas this treatment had not effect on fruit calcium concentration from the top of the canopy. However, the laboratory study showed that 'Jonagold' apples from the canopy top had ability to take up exogenous calcium. It was found that efficacy of CaCl<sub>2<sub> sprays at studied water rates in increasing fruit calcium concentration was similar. The study showed as well that young 'Jonagold' fruitlets took up clearly less exogenous calcium compared to mature fruit which suggests that sprays of this cultivar with calcium salts should be applied mainly at late apple development stages.

Abstract:
Foliar application of hormones and nutrients can improve fruit quality, but specific conditions for applying hormones and nutrients may vary among fruit species. The objective of this study was to determine the effects of 6-BA, potassium phosphate (monobasic), and calcium chloride on fruit weight, palatability, and storage quality of 8-year-old pear trees, cv. Hosui. Foliar applications of 1 mg·L-1 6-BA, 0.3% potassium phosphate, 0.3% calcium chloride, or 0.3% potassium phosphate + 0.3% calcium chloride were made at 20-day intervals from June until maturity. All foliar applications increased average fruit weight over the control (distilled water). 6-BA or the combination of potassium phosphate and calcium chloride increased fruit weight more than did potassium phosphate or calcium chloride alone. Fruit palatability, measured as the ratio of sugar content to acid content, was significantly lower in 6-BA, potassium phosphate, and calcium chloride treatments than in the control. All treatments increased vitamin C content over the control. Fruit storage quality in calcium chloride or calcium chloride + potassium phosphate treatments was superior to that in the control. Potassium phosphate alone and 6-BA treatments had no effects on fruit storage quality. We conclude that foliar applications of 0.3% potassium phosphate + 0.3% calcium chloride or 1 mg·L-1 6-BA can increase average fruit weight and improve fruit palatability.

Abstract:
ABSTRACT Studies related with the storage of peach fruits have received great relevance in Egypt. In this study, the effect of pre-harvest sprays of calcium chloride and chitosan, separately and in combination, on quality attributes and storability of peach fruits stored at 0±1 °C was studied. ‘Early Swelling’ peach trees were sprayed twice with 1% or 2% calcium chloride. The first spraying was at pea stage, while the second one was performed at 10 days before harvesting. Chitosan sprays were performed at 0.5 or 1%, alone or in combination with 1 and 2% calcium chloride, at 10 days before harvesting. Untreated trees served as control. Fruits were harvested at maturity stage, then packaged and stored at 0±1 °C and 85-90% of relative humidity. Fruit physical and chemical properties were evaluated at 7-day intervals. Results showed that pre-harvest application with 2% CaCl2+1% chitosan was most effective in minimizing weight loss (%) and decay (%), as well as in maintaining maximum firmness and lengthening shelf life. Fruit color was not affected by any of the treatments, while untreated fruits and calcium chloride treatment alone, at both applied concentrations, maintained higher total soluble solids (TSS, %), total phenolic content, and lower titratable acidity percentage.

Abstract:
Control of bitter pit in `Honeycrisp' apples (Malus ×domestica) from trees treated during the growing season with foliar sprays of trifloxystrobin fungicide and calcium was evaluated in four replicated trials over 2 years. All trials were in commercial orchards of `Honeycrisp' trees that were 3 to 6 years old. The effectiveness of combining boron with foliar applications of calcium chloride (CaCl2) was evaluated in two trials, and effectiveness of harpin protein, used either alone or in alternating sprays with CaCl2 was assessed in one trial. Trifloxystrobin applied twice during the 30 days before harvest reduced bitter pit incidence at harvest in one of the four trials, but the reduction was transitory, no longer being evident when fruit were re-evaluated after 63 days of cold storage. Harpin protein did not affect disorder incidence. Calcium sprays failed to control bitter pit in treatments where the total elemental calcium applied was less than 2.7 lb/acre (3.03 kg·ha–1) per year for tree canopies that were sprayed to drip using 100 gal/acre (935.4 L·ha–1) of spray solution. In the two trials where some treatments involved application of at least 2.9 lb/acre (3.25 kg·ha–1) of elemental calcium per season, the incidence of fruit with bitter pit at harvest was reduced by 76% to 90%. Effectiveness of calcium sprays for bitter pit control was not enhanced by superimposing trifloxystrobin, boron, or harpin protein treatments. Flesh firmness at harvest was lower in calcium-treated than in non-treated fruit, and fruit maturity was more advanced on trees receiving boron sprays than on trees receiving no boron. In one trial, where the first calcium application was made approximately 2 weeks after petal fall and 4 days prior to a fruit thinning spray, crop load of trees that received calcium sprays, measured as number of fruit per cm2 trunk cross-sectional area, was 38% greater than on trees that received no calcium sprays. CaCl2 provided better control of bitter pit in `Honeycrisp' than any of the other materials tested.

Abstract:
Peach fruit and trees are prone to various issues, regarding yield, quality and pest attack. Calcium plays several roles in plant and fruit development. Therefore the current study was conducted to evaluate the response of peach fruit to foliar application. The experiment was laid out in Randomized Complete Block Design with two factors factorial arrangement and three replicates. Calcium chloride was applied at the rate of 0, 1, 2 and 3%. The foliar application of calcium was done at pink bud stage, berry size fruit stage, and then at pit hardening stage of peach. The obtained resulted indicated that foliar application of calcium significantly improved peach fruit quality and yield. The highest fruit weight (142.6 g), yield tree–1 (15.6 kg), ascorbic acid content (6.67 mg‧100 g–1), total soluble solids (11.0°Bx), fruit juice pH (3.98), sugar to acid ratio (45.1), fruit firmness (3.90 kg‧cm–2) and fruit volume (155.6 cm3) was obtained with the application of 3% solution of calcium chloride at pit hardening stage but it significantly reduced the percent titratable acidity (0.3%) and disease incidence (5.8%). It was concluded that 3% calcium chloride applied at the pit hardening stage significantly boosted peach quality and fruit yield.

Abstract:
Flesh softening, skin browning and rotting are chief problems during cold storage (CS) of 'Fuyu' Persimmon. We studied the effects of boron (B) and calcium (Ca) sprayed on the trees during three consecutive years, on the development of skin cracks, grooves and browning in persimmon fruit under CS in Farroupilha, RS, Brazil (29°31' south, 51°21' west, about 750 m altitude). A homogeneous orchard area of 0.5 ha was delimitated and three sets of five plants for each treatment were randomly selected. The persimmon trees were sprayed at a 20 day interval, from 15th January until harvest, for three consecutive years, with: T1) water; T2) calcium nitrate at 0.5% (m/v); T3) calcium chloride at 0.5% (m/v); and T4) boron at 0.3% (m/v). The fruit were harvest with orange-reddish colour; 18-20°Brix, pulp firmness of 45 to 60N, and kept under CS at 0±1°C for 45 days. The fruits were evaluated immediately before CS, after six hours at 23±2°C after removal from CS, and after four days at 23±2°C after removal from CS. Equally boron and calcium sprayed on the trees prevented skin cracks, skin grooves and skin browning. Besides, when boron was sprayed on the trees, the mentioned effects were additive in the following year.

Abstract:
The aim of this study was to examine effect of frequency of calcium chloride (CaCl<sub>2</sub>) sprays on 'Jonagold' apple (<em>Malus domestica</em> Borkh.) quality. The experiment was carried out in 1996-1998 in the Experimental Orchard of the Research Institute of Pomology and Floriculture in Skierniewice. Apple trees were grafied on M.26 rootstock and planted in 1992 at a distance of 4 x 2 m on a sandy loam soil with high available phosphorus, potassium and magnesium contents. Four experimental treatments were applied: (i) three sprays with CaCl<sub>2</sub> solutions at 2, 10 and 18 weeks after full bloom, (ii) six sprays with CaCl<sub>2</sub> at 2, 6, 10, 14, 16 and 18 weeks after full bloom, (iii) nine sprays with CaCl<sub>2</sub> at 2, 4, 6, 8, 10, 12, 14, 16 and 18 weeks after full bloom and (iv) control plot - trees unsprayed with CaCl<sub>2</sub>. The results showed that fruit Ca concentration increased with the number of CaCl<sub>2</sub> sprays during the growing season. Apples nine-times sprayed with CaCl<sub>2</sub> solutions were smaller, less mature at harvest and after storage, had lower titratable acidity and soluble solids contents after storage and were less sensitive to bitter pit, internal breakdown and Gloeosporium-rot compared to other treatments; however these effects were influenced by the growing season. Six CaCl<sub>2</sub> sprays only in one year of the study increased fruit firmness after storage, fruit resistance to bitter pit and internal breakdown. Three CaCl<sub>2</sub> sprays decreased bitter pit incidence; however this effect was found only in one investigated year.

Abstract:
Eighteen elements, including: carbon, oxygen, sodium, magnesium, aluminum, silicon, phosphorus, sulfur, chlorine, potassium, calcium, titanium, chromium, manganese, iron, nickel, strontium, and barium were measured using a scanning electron microscope with energy dispersive spectroscopy from deposits. The deposits were collected by burning eight different coals in a 160 kWth, staged, down-fired, swirl-stabilized combustor. Both up-stream and down-stream deposits from an oxidizing region (equivalence ratio 0.86) and reducing region (equivalence ratio 1.15) were collected. Within the deposits, the particle size and morphology were studied. The average particle cross-sectional area from the up-stream deposits ranged from 10 - 75 µm2 and had a standard deviation of 36 - 340 µm2. These up-stream particles were of various shapes: spherical, previously molten particles; irregular particle that had not melted, hollowed spherical shells; and layered or strands of particles. These particles were a mixture of burned and unburned coal being deposited at various stages of burnout and having completed some burnout after deposition. The average particle cross-sectional area from the down-stream deposits ranged 0.9 - 7 µm2 and the standard deviation range of 2.6 - 30 µm2. The shape of the particles on the bottom sleeves are typically spherical indicating melting prior to deposition. Particles contained a distribution of elemental compositions that were not tightly grouped on ternary phase diagrams. This indicated that particles were not single compounds or phases but each particle contained a mixture of multiple compounds. Coals' deposit sulfur was strongly correlated with the calcium and iron content of the ASTM ash analysis. The low rank sub-bituminous and lignite coals that had high calcium content produced high sulfur deposits, particularly in the oxidizing region, down-stream deposits. The high iron bituminous coals, also produced high sulfur deposits, but more so in the reducing region, up-stream deposits. The low calcium and low iron coals produced low sulfur deposits. Mahoning was an exception being high in iron content but remaining low in sulfur content in the deposit. Gatling coal showed numerous deposit particles that contained only iron and sulfur consistent with the high pyrite content of Gatling coal. The average concentration of chlorine was insignificant in all of the deposits with the concentration being less than 100 ppm. Individual particles containing chlorine were found and were associated with potassium, sodium, and iron.
