Abstract

Abstract: Seed deterioration induces the formation of free radicals and proliferation of microorganisms, but the application of external antioxidants may lessen these effects. The aim of this study was to investigate the antioxidant and antimicrobial activity of cathode and anode water on the physiological quality and health of Coffea arabica L. seeds. Part of the seeds were soaked in cathode water and the other part in anode water for periods of 1, 6, 12, 24, and 36 hours. The physiological quality of the seeds was evaluated by the germination test and tetrazolium test, and seed health by the Blotter test. Analysis of variance and Pearson correlation analysis were performed on the data for all the response variables. Soaking in cathode water or anode water up to 24 hours improves the physiological quality of coffee seeds. Anode water has a beneficial effect on the health of coffee seeds, reducing the incidence of Fusarium spp., Penicillium spp., Cladosporium spp., and Alternaria spp. after one hour of soaking and of Aspergillus spp. after six hours. Soaking in cathode water for a period of one hour leads to a reduction in the fungi Aspergillus spp., Fusarium spp., Cladosporium spp., and Alternaria spp., and reduction in Penicillium spp. after six hours.

阿拉比卡咖啡种子正极水和负极水的抗氧化和抗菌活性

摘要：种子变质可诱导自由基的形成和微生物的增殖，但应用外源抗氧化剂可能会减轻这些影响。本研究旨在研究阴极水和阳极水对小粒咖啡种子生理品质和健康的抗氧化和抗菌活性。将部分种子浸泡在阴极水中，另一部分浸泡在阳极水中1、6、12、24和36小时。通过发芽试验和四氮唑试验评价种子的生理品质，通过Blotter试验评价种子健康状况。对所有反应变量的数据进行方差分析和Pearson相关分析。在阴极水或阳极水中浸泡长达24小时可以改善咖啡种子的生理质量。阳极水对咖啡种子的健康有有益的影响，在浸泡一小时后降低镰刀菌属、青霉属、枝孢菌属和链格孢属的发病率，在浸泡六小时后降低曲霉菌属的发病。在阴极水中浸泡一小时导致真菌曲霉属、镰刀菌属、枝孢属和链格孢属的减少，并且在六小时后导致青霉属的减少。

期刊介绍： From 2017 the Journal of Seed Science (JSS) will circulate online version only. Original scientific studies and communications, not yet published or submitted to another journal for publication and written in Portuguese or English, will be accepted for publication. For manuscripts submitted in English, the authors should provide an adequated version. The SCIENTIFIC COMMUNICATION is a category of scientific manuscript which describes a technique, an equipment, new species or observations and surveys of limited results. It has the same scientific rigor as the “Scientific Articles” and the same value as a publication. The classification of a manuscript as a SCIENTIFIC COMMUNICATION is based on its content and scientific merit but it can be a preliminary study, simple and not definitive on a certain subject, with publication justified by its uniqueness and contribution to the area. The Editorial Board of the JSS may invite leading authors of recognized reputation to compose specific Review Articles covering topics of their specialization that will convey to the scientific community the state-of-the-art knowledge related to the specific theme.
