Abstract

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’.

果实成熟度和抗氧化活性对‘Abate fastei’梨表面烫伤发展的影响

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。

期刊介绍： Advances in Horticultural Science aims to provide a forum for original investigations in horticulture, viticulture and oliviculture. The journal publishes fully refereed papers which cover applied and theoretical approaches to the most recent studies of all areas of horticulture - fruit growing, vegetable growing, viticulture, floriculture, medicinal plants, ornamental gardening, garden and landscape architecture, in temperate, subtropical and tropical regions. Papers on horticultural aspects of agronomic, breeding, biotechnology, entomology, irrigation and plant stress physiology, plant nutrition, plant protection, plant pathology, and pre and post harvest physiology, are also welcomed. The journal scope is the promotion of a sustainable increase of the quantity and quality of horticultural products and the transfer of the new knowledge in the field. Papers should report original research, should be methodologically sound and of relevance to the international scientific community. AHS publishes three types of manuscripts: Full-length - short note - review papers. Papers are published in English.
