Abstract

Abstract: The association between beneficial microorganisms and green beans can accelerate establishment in the field. The objective of this study was to investigate the influence of seed treatments in different doses of Bacillus subtilis on the physiological potential of green beans. Seeds from the cultivar Macarrão Baixo were used. The study used a completely randomized design in a double factorial scheme with factor A in the treatments: Pelliculation (PC), Pelliculation with Drying (PCD), Pre-Imbibition (PI), Biopriming (BP); factor B, doses of B. subtilis: 0; 7; 14 and 28 mL of a commercial product.kg of seed-1, and a control. The following treatments were applied: moisture content analysis, first count and final germination, electrical conductivity, length, fresh and dry seedling weight, speed index, and final emergence. Analysis of variance was applied to the data and when significant, it was compared using Tukey’s test and polynomial regression; for the absolute control, orthogonal contrast was applied, with p < 0.05 for all analyses. The treatments did not impair seed viability. Vigor benefited with the use of PI and doses between 16 and 20 mL of p.c.kg of seed-1. PI alone had the best performance. Biopriming, associated with B. subtilis, favors the vigor of green beans.

枯草芽孢杆菌处理青豆种子的生理电位
摘要/ Abstract摘要:有益微生物与四季豆之间的关联可以加速四季豆在田间的建立。本研究旨在探讨不同剂量枯草芽孢杆菌种子处理对四季豆生理电位的影响。使用品种macarr o Baixo的种子。本研究采用完全随机设计的双因子方案,并考虑因子a的影响:制膜(PC)、制膜干燥(PCD)、预吸(PI)、生物吸膜(BP);因子B,枯草芽孢杆菌剂量:0;7;14和28毫升的商业产品。1号种子1公斤,对照1公斤。分别进行水分分析、初芽计数和终芽、电导率、幼苗长度、鲜苗和干苗重、幼苗速度指数和终出苗处理。对数据进行方差分析,当数据显著时,采用Tukey检验和多项式回归进行比较;绝对对照采用正交对比,所有分析p < 0.05。这些处理对种子活力没有影响。在每公斤种子-1中施用16 - 20毫升的PI对活力有好处。单独使用PI具有最好的性能。与枯草芽孢杆菌有关的生物熏蒸有利于四季豆的活力。

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.
