Abstract

Abstract: The ethanol test supplies information on physiological problems related to seed deterioration. The test optimization is crucial for its application in the seed analysis routine. This study aimed to evaluate vigor test for Plathymenia reticulataseeds based on ethanol production in order to establish execution guidelines and verify its relationship with other seed vigor tests. Seed lots were subjected to germination and vigor tests, and seed coat evaluation. Ethanol production assessment was carried out based on two trials testing water volumes for imbibition (0.25; 0.5; 0.75; 1.00; and 1.25 mL), reading periods (2, 4, 6, 8, 24, and 48 h), and seed quantities (5, 10, and 15). There was a distinction in physiological potential between the lots, indicated by the ethanol test and other traditionally used tests. The ethanol test was efficient for vigor assessment in Plathymenia seeds, as were the other vigor tests, when conducted with 15 seeds imbibed in a volume of water 2.5 times their mass for 48 h. The vigor test based on ethanol production proved reliable and it is recommended for use in a system of seed production and commercialization in nurseries and forestry companies.

乙醇试验作为森林物种种子生理电位的决定因素——以网纹白腹为例。(豆科-含豆科)，大西洋森林恢复的重要树种

摘要:乙醇试验提供了与种子变质有关的生理问题的信息。在种子分析程序中，测试优化是其应用的关键。本研究旨在对基于乙醇生产的网状白兜种子活力测试进行评价，以建立执行指南，并验证其与其他种子活力测试的关系。对种子进行萌发、活力试验和种皮评价。乙醇产量评估是根据两个试验进行的，测试了自吸水量(0.25;0.5;0.75;1.00;和1.25 mL)，读取周期(2、4、6、8、24和48 h)和种子数量(5、10和15)。乙醇测试和其他传统测试表明，这些批次之间的生理电位存在差异。乙醇试验和其他活力试验一样，在15个种子以其质量2.5倍的水浸泡48小时的情况下，有效地评估了白草籽的活力。基于乙醇生产的活力测试证明是可靠的，建议在苗圃和林业公司的种子生产和商业化系统中使用。

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.
