Abstract

Abstract: Atmospheric plasma application technology consists of a fast and practical method, which has the potential to modify the surface of seeds with integumentary hardness. The aim of this research was to evaluate the effect of applying atmospheric cold plasma on Pityrocarpa moniliformis seeds, assessing its implications on the seed coat impermeability, germination and vigor. Cells were subjected to plasma for 1.5, 2.0, 3.0, 4.0 and 5.0 minutes, using seeds without any treatment as a control. After application, the seed coat wettability, imbibition curve and electrical conductivity of the soaking solution were determined. Seeds were also subjected to the germination test, and its results were used to determine viability, median, uniformity and asymmetry of germination. Seeds subjected to plasma for 5.0 and 4.0 minutes showed the lowest apparent contact angles, 64 and 61°, respectively, characterizing greater wettability of the seed coat among the treatments tested. Higher germination was observed in the treatments with plasma application when compared to the control. Atmospheric plasma application technology has the potential to be used as an accelerator of P. moniliformis seed germination.

大气等离子体克服了圆叶蝉的休眠(下)lucow & R. W. johnson种子公司

摘要:大气等离子体应用技术是一种快速实用的方法，有可能对种子表面的外皮硬度进行修饰。摘要研究了常压冷等离子体处理对圆叶松种子的影响，并对其种皮不透水性、萌发率和活力进行了评价。将细胞置于血浆中1.5、2.0、3.0、4.0和5.0分钟，以未经处理的种子为对照。应用后测定了浸种液的种皮润湿性、渗吸曲线和电导率。种子也进行了发芽试验，并利用其结果来确定萌发的活力、中位数、均匀性和不对称性。等离子体处理5.0和4.0 min的种子表观接触角最低，分别为64°和61°，表明种皮的润湿性较好。与对照相比，施用等离子体处理的发芽率较高。大气等离子体应用技术是一种极有潜力的种子催熟技术。

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.
