摘要

摘要:种子处理是保护种子和幼苗免受病虫害侵害的重要手段。种子处理通常有两种方式:由种子公司进行的工业种子处理(IST)或农场处理(OFT)。这些处理技术都会影响到最终的工艺质量。因此，本研究的目的是在功能质量和剂量应用有效性(DAE)方面描述巴西农业综合企业中ist和oft的种子质量概况。在巴西马托格罗索州、Goiás、帕拉纳、米纳斯吉拉斯州、圣保罗州和圣卡塔琳娜州这6个生产州收集了经过这两种方法处理的种子样本。为评价各处理的功能质量，采用grounddeye®设备高分辨率图像分析测定包膜率，高效液相色谱法测定杀虫剂有效成分DAE量。图像分析被证明是一种很有前途的评价种子包衣的技术，此外，“农场”技术处理的样品在包衣和有效成分剂量方面具有更大的差异和异质性，而工业处理的样品则表现出更高的均匀性，均匀性和有效性。植物检疫产品包衣与处理后玉米种子DAE呈显著正相关，DAE是评价处理质量的重要参数。

Quality of corn seed industrial seed treatment (IST) and on-farm treatment (OFT) in Brazilian agribusiness

Abstract: Seed treatment is important for protecting seed and seedling from pests and/or pathogens. Seed treatment can be performed generally in two ways: industrial seed treatment (IST), performed by seed companies, or on-farm treatment (OFT). These treatment technologies will affect the final quality of the process. Therefore, the objective of this study was to characterize the seed quality profile of ISTs and OFTs in Brazilian agribusiness in terms of functional quality and dose application effectiveness (DAE). Seed samples treated by both processes were collected in 6 producing states of Brazil, Mato Grosso, Goiás, Paraná, Minas Gerais, São Paulo, and Santa Catarina. To evaluate the functional quality of the treatments, the coating percentage was determined by high-resolution image analysis with GroundEye® equipment, and the insecticide active ingredient DAE amount was determined with high-performance liquid chromatography (HPLC). Image analysis proved to be a promising technique to evaluate seed coating, in addition, samples treated with “on farm” technology had greater variation and heterogeneity in coating and active ingredient dose, while samples treated industrially showed greater homogeneity, uniformity, effectiveness of applied products. There was a strong positive correlation between coating with phytosanitary products and DAE in treated corn seeds, important parameters in the evaluation of the quality of the treatment.

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.
