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.
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.
