Abstract

Abstract: The aim of this work was to evaluate the impact of soybean sowing in soil with low water availability, under two management systems, using seeds with and without chemical treatment, on the physiological quality of seeds and seedling emergence. For this, two experiments were set up, one under no-tillage system (NTS) and the other under conventional tillage system (CTS), in a randomized block design, both in a 2x6 factorial scheme, with two seed treatment conditions (with and without) and six periods of seed permanence in the soil (0, 24, 48, 72, 96 and 120 h), with four replications. Germination, vigor, percentage of abnormal seedlings and percentage of dead seeds were evaluated. Seed treatment made it possible to maintain germination at acceptable levels for up to five days of permanence of the seeds in the soil, even in CTS. Sowing in soils with low water availability can lead to reductions of 0.2 and 0.5 percentage points per hour of exposure to dry soil in germination and vigor of soybean seeds, respectively.

低水分条件下大豆播种:种子处理和土壤管理的影响

摘要:本试验旨在评价大豆在低水分有效度土壤中，在两种管理制度下，施用和未施用化学处理种子对种子生理品质和出苗的影响。为此，采用随机区组设计，采用2 × 6因子设计，分别设置免耕(NTS)和常规耕作(CTS)两种制度，两种种子处理条件(带和不带)和种子在土壤中停留6个周期(0、24、48、72、96和120 h)， 4个重复。测定萌发率、活力、异常苗率和死种子率。种子处理可以使种子在土壤中保持可接受的萌发水平长达五天的持久性，即使在CTS中也是如此。在水分利用率低的土壤中播种，大豆种子的萌发率和活力在干燥土壤中每小时分别降低0.2和0.5个百分点。

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.
