Fan, L., Yu, C., Fang, C., Zhang, M., Ranieri, M., Dubé, C. and Khanizadeh, S. 2011. The effect of three production systems on the postharvest quality and phytochemical composition of Orléans strawberry. Can. J. Plant Sci. 91: 403–409. The effects of two production systems, plastic mulch (PM) and plastic mulch with row covers (PMRC) versus the commonly used matted-row system (MRS) on postharvest fruit quality, including shelf life, fruit weight loss and juice leakage, fruit glossiness, postharvest disease caused by grey mould (Botrytis cinerea Pers.), and chemical composition of Orléans strawberry were evaluated during 2008 and 2009. Plastic mulch with row covers accelerated fruit maturity by 7 to 10 d and produced larger fruits compared with the MRS. Production systems significantly changed the total phenolic content (TPC) and total antioxidant content (TAC), but the effect varied during the harvest season. Total phenolic content was significantly higher for PMRC than MRS and PM at early harvest, but the effect was similar to PM at mid and late harvest. Total antioxidant content was significantly higher for PMRC compared with MRS and PM at all stages of fruit production, especially at late harvest. Fruit weight loss and juice leakage and the presence of grey mould during storage were lower and fruit glossiness was higher for those harvested under PMRC compared with those from MRS. No significant differences were observed for firmness, pH, titratable acidity (TA) and soluble solids content (SSC) between the three production systems. Titratable acidity and SSC of PMRC were slightly higher than those from MRS and PM, but the differences were not significant. It seems that PMRC not only accelerates ripening, but also has a significant effect on pre- and postharvest fruit quality and chemical composition of the harvested fruits.

Background: Present study, aimed to assess effect of organic and inorganic crop mulching on physical, physiological and biochemical quality of fresh cowpea beans.Methods: Cowpea (cv. Kashi Kanchan bush-type) was grown during two consecutive seasons from April 2018 to July 2019 under four different mulching treatments. Mulching treatments included no mulch; wheat straw mulch (organic mulch); black mulch and silver mulch. Black and silver mulches were made of 25 microns LDPE sheet. Cowpea was grown as per standard agronomic practices and physical, biochemical and postharvest quality parameters of beans were evaluated.Result: Results indicated that bean length (28.7cm) was highest under silver mulch whereas bean thickness (9.10mm), width (9.29mm) and 100 bean weight (1094.5g) were highest under organic mulch. Likewise, protein content (28.63%), total phenolic content (17.0µg GAE/100g) and total antioxidant activity (46.84µmol trolox equiv./100g) were found highest in beans produced under organic mulch. Overall results demonstrated that crop mulching could be used for enhancing the antioxidants, phenolic content of cowpea beans.

Twenty two brinjal (Solanum melongena L.) genotypes were collected and grown in summer season and variability estimates were studied for twenty two different quality, yield, its attributing traits. High genotypic and phenotypic coefficient of variation was obtained for characters like length of style, fruit girth, average fruit weight, number of fruits per plant, yield per plant, total yield per hectare, total sugar, reducing sugar, titrable acidity, ascorbic acid, total antioxidant capacity, total phenolic content and polyphenol oxidase. Heritability and genetic gain as percent of mean was observed to be high for characters such as plant height, number of primary branches, length of style, fruit length, fruit girth, average fruit weight, number of fruit per plant, yield per plant, total yield per hectare, TSS, total sugar, reducing sugar, titrable acidity, ascorbic acid, total antioxidant capacity, total phenolic content and polyphenol oxidase. High heritability coupled with high predicted genetic gain suggests for selection based on these traits for enhancement of yield and quality.

Over three years the postharvest quality of 'Marli' peaches harvested from the integrated (IFP) and conventional production (CFP) systems was evaluated. The peaches were harvested from commercial orchards of Prunus persica at two locations close to the city of São Jerônimo, RS, Brazil, and stored at 0.5°C for 10, 20 or 30 days. The peaches were evaluated at harvest, at retrieval from storage and after ripening periods at 20°C. No differences in fruit weight losses were determined. Decay incidence was low, and no differences were detected amongst systems in both 2001 and 2002 seasons, but in the 2000 season CFP peaches were more decayed. Flesh firmness of peaches from the IFP system were greater than CFP fruits in the years 2000 and 2001. In 2002, firmness changed little during storage and ripening. Peaches from the IFP in 2000 had higher titratable acidity and lower soluble solids. In the 2000 season, flesh browning was observed in decayed fruits, always at ripening after 20 or 30 days of cold storage Chilling injuries such as browning, woolliness and leatheriness ocurred in 2002. There were no differences amongst systems related to peach quality.

Biochemical Characteristics

The northeastern Anatolia region of Turkey is one of the richest plant biodiversity areas in Turkey. This study describes some important tree and fruit characteristics of 20 seed-propagated summer apple genotypes from northeastern Anatolia using morphological and biochemical markers. The genotypes were evaluated morphologically for tree growth habit, ripening date, fruit weight, fruit firmness, fruit shape, fruit color, fruit taste, juiciness and aroma. The biochemical characteristics measured were organic acids, SSC (soluble solid content), titratable acidity, vitamin C, total phenolic content and antioxidant capacity. We found significant differences for most of the morphological and biochemical characteristics. The genotypes exhibited quite diverse harvest dates ranging from 4 July to 16 August. Summer apple genotypes had fruit weight between 101.9 g and 133.5 g. The genotypes had diverse fruit shapes, including round, conic and oblate, and over fruit colours such as pink, red, yellow and green. Genotypes GUM7 and GUM13 stood out for fruit weight, SSC, total phenolic and antioxidant capacity. GUM7 and GUM13 present dissimilarity from the other genotypes. While the first showed a lower average fruit weight, SSC, total phenolic content and antioxidant capacity, the second revealed higher average of fruit weight, total phenolic content, antioxidant capacity and higher SSC. Due to their favorable characteristics, GUM13 can be used for further crosses with genotypes of other groups, which also present favorable characteristics.

Phytochemical Content

In this study, the effect of different harvest period on fruit quality and phytochemical properties of short and day neutral strawberries was investigated. For this purpose, two day-neutral ('Fern', 'Kabarl') and four short day ('Camorosa', 'Sweet Charlie', 'Rubygem' and 'Festival') strawberry varieties were harvested at three different harvest period. Harvested fruits were analysed 15 and 30 days intervals for short and day-neutral varieties. Pomological analysis such as fruit size, firmness, fruit weight, titratable acidity (TA), total soluble solids (TSS), pH and total anthocyanin, total phenolic content and antioxidant capacity were studied. Results of the present study indicated that fruits from later harvest periods displayed smaller fruit size, lower pH and TSS content but higher TA and fruit firmness. Also, both short and day neutral varieties have higher phytochemical content at later harvest period in terms of total phenolics, total anthocyanin and antioxidant capacity.

The impact of ozone concentration and ozonisation time on the selected chemical, physical and microbiological properties of Rapanui tomatoes was investigated. Tomatoes were exposed to gaseous ozone at concentrations of 0.9 and 2.5 mg L−1 (c1, c2) for 30 and 120 min (t1, t2), and stored for up to 15 days at a temperature of 12 ± 1 °C. The following parameters were evaluated: titratable acidity, total soluble solids, total phenolic and flavonoid contents, lycopene, total carotenoids, vitamin C, total antioxidant activity, colour L* a* b* and firmness. Ozonated fruit had higher levels of total soluble solids and higher levels of titratable acidity during and after storage. Exposure of tomatoes to a cooling atmosphere, applying recommended ozonisation process parameters, efficiently inactivated microorganisms that are present on the surface and reduced fruit weight loss, while retaining their firmness and stable colour.

Surface browning after harvest is the primary constraint affecting the storage life and market circulation of rambutans. In this study, rambutan fruits were soaked in sodium nitroprusside at different concentrations and stored at 25°C for 8 days to explore the effects on postharvest quality and browning. The weight loss, browning index and superoxide anion radical, hydrogen peroxide and malondialdehyde contents of the treated fruits were reduced compared to those of the control fruits (soaked in distilled water). And fruits treated with sodium nitroprusside had a higher total phenolic content and lower polyphenol oxidase and peroxidase activity. In addition, compared with the control, the treated fruits exhibited higher phenylalanine ammonia lyase, ascorbate peroxidase and superoxide dismutase activities; titratable acidity; and soluble solid, vitamin C and protein contents, indicating high fruit quality. Overall, sodium nitroprusside treatment at 200 μmol L−1 demonstrated the most positive preservation effects. Therefore, sodium nitroprusside treatment, particularly at 200 μmol L−1, can be used as an eco-friendly, safe and convenient method for postharvest quality management and high-efficiency preservation of rambutan fruits.

Avocado peel has been considered as a potential source of natural antioxidants in which phenolics are among the most important compounds. Therefore, this study aims to optimize the extraction process of phenolics using response surface methodology and evaluate the corresponding antioxidant activity. From the quadratic model, the optimal condition was determined including the ethanol concentration 54.55% (v/v), the solvent/solute ratio 71.82/1 (mL/g), temperature 53.03 oC and extraction time 99.09 min. The total phenolic content and the total antioxidant capacity at this condition with minor modifications were 26,74 ± 0,04 (mg GAE/g DW) and 188.06 ± 1.41 (mg AAE/g DW), respectively. The significant correlation between total phenolic content and total antioxidant capacity was also confirmed.

In this research, the total phenolic content (TPC) and antioxidant capacity (FRAP and DPPH•× assays) of pulps and peels of advanced selection of apples grown in Brazil were investigated. The correlation analyses between the activity of polyphenoloxidase enzyme (PPO), vitamin C content, total titratable acidity, and color parameters were performed. The results indicated that the data differed significantly among the apple genotypes studied. The peels of the selection Epagri 170-91 and Epagri 170-25 showed the highest TPC and antioxidant capacities. In addition, the pulps of the Epagri 170-91 presented the highest TPC and antioxidant capacities, the lowest enzymatic browning, highest amount of vitamin C and lowest enzymatic activity when compared with other genotypes. The TPC and antioxidant capacities were significantly correlated in all genotypes analyzed. High correlation values between enzymatic browning and factors that affect the apple color were also found in all analyzed pulps, except between enzymatic browning and TPC. The results demonstrated that the enzymatic browning and TPC, as well as the antioxidant capacity and chemical characteristics, vary considerably depending on the apple genotypes and fruit tissues analyzed.

Sideritis niveotomentosa Hub. -Mor. is a local endemic species belonging to the Lamiaceae family. In this study, GC/MS analysis, total antioxidant capacity and anticancer effects of different extracts obtained from S. niveotomentosa were investigated comparatively. Total phenolic contents of extracts were determined by the Folin–Ciocalteu method, total flavonoid contents by aluminum chloride method, and also the free radical scavenging activities of the extracts by DPPH (2,2-diphenyl-1-picryl-hydrazyl-hydrate) assay. The cytotoxic effect of the extracts was studied via MTT (3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide) assay on DLD1, HL60 and ARH77 cell lines. Pro-apoptotic gene expression levels were also tested in the most sensitive cell line ARH77 by Real-Time PCR. The expression levels of 4 pro-apoptotic genes, APAF, BAX, CASP3, and HRK were found to be upregulated in ARH77 cells that were treated extracts. Results showed that methanolic extracts contain more phenolic content than acetone extracts, consistent with DPPH results. As a result, Sideritis niveotomentosa extracts, especially methanolic extracts, are rich in phenolic content and have a strong radical scavenging effect. In addition, the extracts showed selective effects on cell lines. This study is pioneering in terms of future studies, and the findings provide hope for future experimentation.
