Abstract

Abstract: The accelerated aging test is widely used to evaluate the vigor of soybean seeds. Currently, the methodology recommended in the literature is to set up the germination test at most one hour after the seed aging process, which makes it difficult to set up and evaluate a large number of samples. The aim of this study was to assess the effect of delay in setting up the germination test after the process of accelerated aging of soybean seeds, specifically its effect on seed physiological performance. We tested three seed lots of the soybean cultivars BRS 397, BRS 399 RR, BRS 1007 IPRO, BRS 1010 IPRO, and BRS 388, all within the standards required for commercialization. The seed lots were physiologically characterized by evaluation of moisture content, germination, seedling vigor classification, tetrazolium test (viability and vigor) and accelerated aging test. The treatments consisted of hours (0, 1, 2, 3, 4, 5, 6, 7, and 8) of delay in setting up the germination test after accelerated aging. A delay of up to eight hours in setting up the germination test after the accelerated aging process of soybean seeds has no direct relationship with the result of assessment of the physiological performance of the seed lot.

大豆种子在加速老化试验中的生理表现及等待期的萌发

摘要:加速老化法是评价大豆种子活力的常用方法。目前，文献中推荐的方法是在种子老化过程后最多1小时设置发芽试验，这给大量样品的设置和评价带来了困难。本试验旨在探讨大豆种子加速老化后延迟设置发芽试验的影响，特别是对种子生理性能的影响。我们对3个大豆品种BRS 397、BRS 399 RR、BRS 1007 IPRO、BRS 1010 IPRO和BRS 388的种子批次进行了测试，均达到商业化标准。通过对种子含水率、萌发率、幼苗活力分级、活力和加速老化试验等进行生理表征。加速老化后分别延迟0、1、2、3、4、5、6、7、8小时设置发芽试验。大豆种子加速老化后设置发芽试验的时间延迟达8小时，与种子批生理性能评价结果无直接关系。

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.
