Abstract

BACKGROUND:Postharvest decay caused by Botrytis cinerea (gray mold) and Fusarium solani (fruit decay) negatively affects strawberry fruits during handling and marketing. OBJECTIVE:The effect of cinnamon oil, sodium benzoate, potassium sorbate and/or pomegranate peel powder were estimated on the growth of the two pathogenic fungi and their fruit decay incidence under in vitro and in vivo conditions. METHODS:The isolated fungi from decayed strawberry fruits were identified as Botrytis cinerea and Fusarium sp. The isolated Fusarium sp. was identified molecularly as Fusarium solani and registered in GenBank under accession number ON248575.1 (https://www.ncbi.nlm.nih.gov/nuccore/ON248575.1). RESULTS:Complete fungal growth suppression was observed at a concentration of 3% for all tested materials, Additionally the same (100%) effect was achieved at 2% of a combination of essential oil, salts and pomegranate peel powder. Significant reduction in decay incidence and severity was observed in inoculated strawberry fruits treated with the same concentrations of the tested materials after 10 and 15 days of storage. CONCLUSIONS:The results demonstrate that cinnamon oil, sodium benzoate, potassium sorbate and/or pomegranate peel powder have potency as eco-friendly products, for safe postharvest treatments against strawberry fruit rots during storage. They could be recommended for use in packing-houses due to their wide utilization as safe food preservatives.

添加一些抗氧化剂化合物对缓解草莓果实在贮藏过程中腐烂的功效

背景：由灰霉病菌（Botrytis cinerea）和果实腐烂镰刀菌（Fusarium solani）引起的采后腐烂对草莓果实的处理和销售产生了负面影响。目的：在体外和体内条件下，评估肉桂油、苯甲酸钠、山梨酸钾和/或石榴皮粉对两种病原真菌的生长及其果实腐烂率的影响。方法：从腐烂的草莓果实中分离出的真菌被鉴定为灰霉病菌（Botrytis cinerea）和镰刀菌（Fusarium sp.）。分离出的镰刀菌经分子鉴定为索氏镰刀菌（Fusarium solani），并在 GenBank 中注册，登录号为 ON248575.1 (https://www.ncbi.nlm.nih.gov/nuccore/ON248575.1)。结果：所有测试材料在 3% 的浓度下都能完全抑制真菌生长，此外，在 2% 的精油、盐和石榴皮粉混合浓度下也能达到相同（100%）的效果。贮藏 10 天和 15 天后，用相同浓度的测试材料处理接种的草莓果实，发现腐烂发生率和严重程度显著降低。结论：研究结果表明，肉桂油、苯甲酸钠、山梨酸钾和/或石榴皮粉作为生态友好型产品，对草莓果实在贮藏期间的腐烂病具有安全的收获后处理作用。由于它们被广泛用作安全的食品防腐剂，因此可推荐在包装车间使用。

期刊介绍： The main objective of the Journal of Berry Research is to improve the knowledge about quality and production of berries to benefit health of the consumers and maintain profitable production using sustainable systems. The objective will be achieved by focusing on four main areas of research and development: From genetics to variety evaluation Nursery production systems and plant quality control Plant physiology, biochemistry and molecular biology, as well as cultural management Health for the consumer: components and factors affecting berries'' nutritional value Specifically, the journal will cover berries (strawberry, raspberry, blackberry, blueberry, cranberry currants, etc.), as well as grapes and small soft fruit in general (e.g., kiwi fruit). It will publish research results covering all areas of plant breeding, including plant genetics, genomics, functional genomics, proteomics and metabolomics, plant physiology, plant pathology and plant development, as well as results dealing with the chemistry and biochemistry of bioactive compounds contained in such fruits and their possible role in human health. Contributions detailing possible pharmacological, medical or therapeutic use or dietary significance will be welcomed in addition to studies regarding biosafety issues of genetically modified plants.
