In the hilly area of Gioia Tauro (Calabria, Southern Italy), lemon orchards are grown in consociation with centuries-old olive trees. Lemons are partially shaded by olive canopies and the microclimate at the level of their canopies is suitable for plants growth and quality productions. Under these conditions, lemon trees are grown even without irrigation, providing, despite this limitation, a quality product. This study aimed to i) investigate the qualitative characterisation of two clonal selections of the lemon cultivar Femminello, F. Siracusano (S) and F. Zagara bianca (ZB), from the described intercropping, on irrigated (I) and non-irrigated (NI) crops; ii) assess the quality preservation during cold storage, in order to evaluate the availability of lemons for marketing in a period of shortage such as the summer season. Fruits were harvested at commercial maturity, and cold stored at 10±1°C and RH 85-90%, for 60 days. Decay incidence, physiological disorders, weight loss, and the main physical-chemical parameters were assessed at harvest (T0) and every 15 days (T15, T30, T45, T60). The absence of decay and physiological disorders was observed throughout the 60-day storage period, in both clonal selections under the two management conditions. The weight loss was greater in fruits from irrigated lemon groves of both S and ZB. S_I showed significantly lower fruits weight and higher titratable acidity than S_NI. Total soluble solids and titratable acidity were statistically lower for ZB_I than for NI fruits.
在乔亚陶罗(意大利南部卡拉布里亚)的丘陵地区，柠檬果园与数百年历史的橄榄树一起种植。柠檬部分被橄榄树冠遮蔽，其树冠水平的小气候适合植物生长和优质生产。在这种条件下，即使没有灌溉，柠檬树也能生长，尽管存在这些限制，但仍能提供高质量的产品。本研究旨在i)研究柠檬品种Femminello, F. Siracusano (S)和F. Zagara bianca (ZB)在灌水(i)和非灌水(NI)作物中间作的两个无性选择的定性特征;Ii)评估冷藏期间的质量保存，以便评估柠檬在短缺时期(如夏季)销售的可用性。果实在商业成熟时收获，在10±1°C和85-90%的相对湿度下冷藏60天。在收获时(T0)和每15天(T15、T30、T45、T60)评估腐烂发生率、生理失调、体重下降及主要理化参数。在60天的贮藏期内，两种管理条件下的克隆选择均未出现腐烂和生理障碍。S和ZB灌溉柠檬林的果实减重更大。S_I的果实质量显著低于S_NI，可滴定酸度显著高于S_NI。ZB_I果实的可溶性固形物总量和可滴定酸度均低于NI果实。

The general aim of the project SUS&LOW is to increase the sustainability of fresh produce by testing and implementing low-input agricultural practices (LIP) with positive impact on product quality with the support of non-destructive (ND) tools for real-time quality assessment and for product discrimination. Additionally, new marketing strategies are generated to better support the added value of the products and to satisfy the final consumers’ preferences. The SUS&LOW project consists of three work packages (WP) and the adopted methodology used two model crops: rocket salad and tomato. The WP1, focused on the reduction of agricultural inputs, showed that sensor-based fertigation management might improve sustainability of soilless cultivation. Results coming from WP2, aimed to the evaluation of ND techniques, outlined the high potentiality of hyperspectral imaging (HSI) and Fourier transformed-near infrared (FT-NIR) techniques for the authentication of sustainable growing methods. Moreover, project activities’ proved computer vision system (CVS) as an effective tool for evaluating the product quality also through the bag. The WP3, dealing with marketing strategies, indicated a positive approach of consumers compared to LIP products certified through a visual storytelling platform.

Carried out within the LIFE17ENV/IT/000347-SUBSED project, this research aimed at investigating the effect of a treated sediment (TS) as substrate component on the quality and marketability of three widespread containerized ornamental species: cherry laurel (Prunus laurocerasus) cv. Novìta, calla lily (Zantedeschia aethiopica) and protea (Protea cynaroides) cv. Little Prince. The TS was mixed with soilless substrates as sphagnum peat, coir, and bark in different proportion (0%, 25% and 50%). In cherry laurel, the TS used in 25 - 50% proportions reduced plant height, slightly altering its attractive vibrant foliage. A positive effect of the TS was evidenced on calla lily, where both tested sediment-based mixtures allowed a copious blooming and flower quality raised as the sediment content increased (TS 50% > TS 25% > TS 0%). Post-harvest longevity and colour of flowers were not affected by substrate composition. The effect of sediment-based substrates on protea growth and blooming showed an opposite trend (TS 0% > TS 25% > TS 50%), with plants grown on 50% v/v TS exhibiting a considerable reduction in plant growth and production of flower clusters, with brighter tones turning towards purple. Based on sale values, the TS proved to be a sustainable alternative for the production of potted ornamentals if properly mixed with other organic matrixes, such as peat and coir.

Punica granatum L. contains several bioactive compounds with antioxidant activity that have a positive effect on human health. This study aims to investigate the changes in the chemical-physical and qualitative parameters of pomegranate fruits cv. Acco from harvest up to +90 days of cold storage (+4°C and 95% RH). Morphological parameters, juice yield, weight loss, total soluble solids content (TSS), pH, titratable acidity, the color of the epicarp (L*, a*, b*), content of polyphenols, anthocyanins, flavonoids, and antioxidant activity were analyzed. The results showed an increase (about 29%) in the juice content (%) at +60 days of cold storage. Cold storage has also shown positive effects on some bioactive compounds. Flavonoids and anthocyanins content increase from 287.98 mg CE/100 ml of juice to 389.23 mg of CE/100 ml of juice and from 8.32 to mg/100 ml of juice to 11.13 mg/100 ml of juice at + 90 days of cold storage, respectively. On the basis of our results that confirmed the literature data, the pomegranate fruit is rich in bioactive compounds that exert beneficial actions on human health, and it has also been demonstrated that such nutraceutical compounds increased during cold storage, allowing the fruit to be preserved a long term.

Table grapes are characterized by high susceptibility to mold development during post-harvest, mostly due to Botrytis cinerea. Microwave application on ready-to-eat product can represent an alternative to antifungal treatment. With the aim of identifying the maximum energy that can be applied on grape without detrimental effects a Central Composite Design was developed testing the application of 10 combinations of treatment time (seconds) and microwave power (Watt). As a result, energies above 8000 kJ negatively affected the sensorial quality of fresh product, both in the presence and absence of B. cinerea inoculum (106 log CFU g-1). The physico-chemical parameters did not show significant differences, but two time/power combinations improved sensory quality of table grape, being selected for the subsequent packaging trial: 14 s/100 W and 80 s/100 W. Treatments were applied before or after packaging in polypropylene bags. At the end of storage period, 100 W applied for 80 seconds before packaging led to a better external appearance of the product than the other treatments, maintaining an intermediate level of mesophilic bacterial load and no significant differences in terms of nutritional quality. 80 seconds at 100 Watt combined with packaging can represent a valuable starting point for further experiments.

Edible flowers are appreciated due to their aesthetic features, nutritional value and antioxidant properties. Tulbaghia simmleri Beauv. (Amaryllidaceae family) flowers are characterized by a pleasant garlic taste and are consumed both as fresh and dried products. The aim of this work was to assess the effect of chilling temperature (+4°C) on the visual quality, nutritional content, and aroma profile of T. simmleri flowers after two (T2) and six (T6) days of storage. Colorimetric analysis highlighted a reduction in petal brightness at T6 and hence their darkening, due to a significant increase in a* coordinate and decrease in the b* one. Total polyphenols and flavonoids content remained unchanged until the end of the experiment, while total anthocyanins increased at T2. Flowers antioxidant activity (DPPH assay) decreased progressively during cold storage, while catalase (CAT) and ascorbate peroxidase (APX) activities increased. The aroma profile was analyzed by HS-SPME associated with GC-MS, underlining that fresh flowers were dominated by high content in monoterpenes (around 80%), with 1,8-cineol as main compound (53.1%). Cold storage reduced this class of volatiles while sesquiterpenes and non-terpenes increased; between them, benzyl benzoate reached 12%.

Pot experiment was conducted to evaluate the effect of chitosan or brassinolide applications on morphology and physiology parameters of Azadirachta indica grown under water deficient stress. The plants received different irrigation intervals, and were sprayed monthly with either chitosan or barrasenolide each at concentrations of 50, 100 and 200 ppm, while the control plants were sprayed only with tap water. The results showed that water stress reduced all growth parameters, chemical constituents of pigments content, total carbohydrates, N, P and K %, total indoles, while proline and total phenols content were increased. Instead, the plants sprayed with the higher concentrations of chitosan or brassinolide resulted in significant increase in growth parameters, pigments content, total carbohydrates, proline content, N, P and K %, total indoles while reduced total phenols content. Based on the obtained results it can be concluded that, foliar application of chitosan or brassinolide at 200 ppm can alleviate the adverse effects of water deficient stress on the growth and physiology parameters of Azadirachta indica.

Caprifig is a valuable candidate for fig breeding programs as it typically grows naturally under non-optimal conditions. The present study was carried out to evaluate the biochemical/morphological characteristics of 18 caprifig cultivars indigenous to the Darab region/southern Iran with 4 replications in a completely randomized block design. From each cultivar, healthy uniform leaf samples and spring fruits were taken and analyzed. Our results showed that 'Naneghasem' had the highest leaf α-tocopherol and polyphenol concentration. The highest leaf ascorbic acid concentration was obtained from the Gol Khengi cultivar (17.03 μg g-1 fresh weight). Also, the contents of chlorophyll, carotenoids, and anthocyanins were significantly different among the studied cultivars. Various cultivars had different absorption potentials for essential elements as macro and micronutrients concentration in the leaves were statistically different in various caprifigs; 'Naneghasem' had the highest Ca (4.46 mg g-1 dry weight) and Fe (67.71 mg kg-1 dry weight) concentration and the highest leaf K concentration (22.46 mg g-1 dry weight) was observed in 'Mahali Layzengan'. In conclusion, 'Naneghasem' was evaluated as a cultivar which seems to be more morphologically- and biochemically-distant from other studied caprifig varieties and probably more adaptable/tolerant to environmental conditions.

The use of intergeneric grafting has been reported as an alternative to manage rootknot nematodes in okra, but the compatibility for grafting has only been tested in a few okra (Abelmoschus esculentus L. Moench) cultivars. The kenaf (Hibiscus cannabinus L.) is resistant to rootknot nematode species and is a potential rootstock for okra. The objective was to study the compatibility of kenaf as rootstock with okra cultivars. It was used a completely randomized design, in factorial scheme 3x10, with five repetitions. The compatibility was assessed by measuring several vegetative characteristics. All cultivars are compatible for grafting with kenaf as rootstock. Grafting onto kenaf may be an option to control rootknot nematodes.
属间嫁接已被报道为管理秋葵根结线虫的一种替代方法，但嫁接的相容性仅在少数秋葵(Abelmoschus esculentus L. Moench)品种中进行过测试。红麻(Hibiscus cannabinus L.)对根结线虫具有抗性，是秋葵潜在的砧木。目的是研究红麻作为砧木与秋葵品种的亲和性。试验采用完全随机设计，阶乘方案为3x10，重复5次。通过测定几种营养性状来评价相容性。所有品种都适合以红麻为砧木嫁接。嫁接到红麻上可能是控制根结线虫的一种选择。

Grafting onto kenaf may be an option to control rootknot nematodes.","PeriodicalId":7339,"journal":{"name":"Advances in horticultural science","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70128633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Superficial scald (SS) is one of the main physiological disorders affecting postharvest of pears. Its onset is linked to oxidative processes. Antioxidant compounds such as ascorbic acid and phenolics could play a key role in preventing SS. Growing environment and fruit quality also have an influence on SS symptoms occurrence. The aim of this project is to understand the relationship between antioxidant activity, phenolic content, and development of SS in ‘Abate Fétel’ pear. Moreover, the effect on SS of fruit maturity at harvest was assessed using multivariate statistical approach. Data were collected in thirty orchards in the Emilia-Romagna region (Italy) in three seasons (2018, 2019 and 2020), and the fruit were stored in a regular atmosphere for 120 days. Antioxidant capacity was determined by 2,2-diphenyl-1-picrylhydrazy (DPPH) method and total phenol content by Folin-Ciocalteau colorimetric protocol. The results showed that 340 mg of ascorbate/100 g of FW and 300 mg of gallic ac./100 g of FW at least provide good protection against SS. Multivariate analysis indicated that pulp firmness and index of absorbance difference ( lAD ) seem to keep low the SS occurence, when at harvest are higher than 6.3 kg and 1.9, respesctively. In conclusion, it would be possible to build a forecasting model to control SS that considers pre-harvest data and content of antioxidants in different orchards, to improve the postharvest management of ‘Abate Fétel’.
浅表烫伤（SS）是影响梨采后生产的主要生理障碍之一。其发病与氧化过程有关。抗氧化剂如抗坏血酸和酚类物质可能在预防SS中发挥关键作用。生长环境和果实品质对SS症状的发生也有影响。本项目的目的是了解‘Abate Fétel’梨的抗氧化活性、酚类含量和SS发育之间的关系。此外，使用多变量统计方法评估了收获时果实成熟度对SS的影响。在艾米利亚-罗马涅地区（意大利）的30个果园收集了三个季节（2018年、2019年和2020年）的数据，并将水果在常规大气中储存120天。用2，2-二苯基-1-苦基肼（DPPH）法测定抗氧化能力，用Folin-Ciocalteau比色法测定总酚含量。结果表明，340mg抗坏血酸盐/100 g FW和300mg没食子酸盐/100 g FW至少提供了对SS的良好保护。多因素分析表明，果肉硬度和吸光度差异指数（lAD）似乎保持较低的SS发生率，收获时分别高于6.3kg和1.9。总之，有可能建立一个预测模型来控制SS，该模型考虑了不同果园的采前数据和抗氧化剂含量，以改善“Abate Fétel”的采后管理。
