Instructions to authors

Scope and editorial policy


  • Amazonian Journal of Plant Research (AJPR) is a journal of the Federal University of Pará in Altamira, a city in Pará state, north of Brazil. AJPR publishes original articles which contribute to the advancement of the Agronomy, Agricultural Sciences, Animal Science, and Forest Science.


  • AJPR is devoted for the publication of Original Research Papers, Brief Communications and Review Articles.


  • The scopes of the journal include the topic areas: Agricultural Mechanization, Agrometeorology, Breeding, Crop Sciences, Food Technology, Genetics, Horticulture, Irrigation and Drainage, Microbiology, Ornamental Plant, Plant Protection,  Pathology, Plant Physiology, Plant Nutrition, Plant Biotechnology (Germplasm Cryopreservation), Postharvest, Precision Agriculture, Soil Sciences, and all fields of Forest ecosystems and their functions including those in the landscape and wood production chain (Wood technology, Wood Chemistry, Wood Biodegradation and Biodeterioration, Non-Timber Products, Biorefinary and Renewable Materials).


  • Original manuscripts evaluated by the Editorial Board may be submitted to peer review or rejected without further review.  The journal have not article submission charges.


  • Submitted manuscripts are reviewed by more than two reviewers. Reviewed manuscripts are sent back to the corresponding author along with comments from reviewers.

In submitting revised manuscripts, authors are requested to submit explanations on how the revisions were made and the reason why they do not agree with the reviewers for those points on which they have no revision. A manuscript is considered withdrawn, if the author has not responded in 3 months to a request for revision. The corresponding authors will be notified for acceptance.


  • Once the manuscript is approved, the authors grant an exclusive license to publish the Submitted article electronic format including photographs that may be selected as a cover image.


  • The copyright law also requires that the authors must provide to the AJPR the permissions to use copyrights material that was published by others journals or publishers, which include figures, tables and images. The permissions must be uploaded in the system as a supplemental file.

Up to four references written in languages other than English will be allowed without justifications. More than that will only be allowed if the authors explain the reasons for keeping them in the text. If allowed by the Editor-in-Chief, these extra references must be cited in English with the text in the original language provided at the end of the reference, in the following format: (in Portuguese, with abstract in English)


  • Amazonian Journal of Plant Research (AJPR) does not recommend that authors cite statistical analyses or software packages as references. These tools should be mentioned in the text (Materials and Methods) by including the specific procedure and the name of the software with its version and/or year, e.g., “…statistical procedures were conducted using PROC NLIN in SAS (Statistical Analysis System, version 9.2)”.


  • References and citations in AJPR articles should be formatted in the ‘author, year’ or ‘name (year)’ style. Remember to ensure that text citations match the list of references. Examples:


  1. a) Single author: Vieira (2015) or (Vieira, 2015).


  1. b) Two authors: Simões and Ferreira-da-Silva (2012) or (Simões and Ferreira-da-Silva, 2012).


  1. c) Three or more authors: Rainério et al. (2010) or (Rainério et al., 2010).


  1. d) Arrange references alphabetically and chronologically within brackets, and use semicolons (;) to separate multiple citations within brackets, e.g.: (Boleli, 2003; Boerjan, 2006; Muraroli and Mendes, 2003).


  1. e) Order multiple citations ‘same author-same date’ with the aid of lower case letters, e.g.: (Santos, 2009a, b).


  1. f) Use the “author-year” style to format the list of references, and: (i) do not abbreviate any other words apart from the first and middle names of authors; (ii) use all capitals only for acronyms, i.e., when the author is an organization; (iii) name all authors and capitalize authors’ last name and initials, which should be separated by a period (.); (iv) separate authors by semicolon; (v) do not use ampersands (&) in the citations nor in the reference list; (vi) do not use bold characters to highlight any part of the reference; (vii) capitalize books and periodical titles; (viii) do not use a comma (,) to separate the title and volume of a periodical; (ix) separate the periodical volume from the page numbers with a colon (:); (x) use full page numbering; (xi) separate page numbers with a dash (-); (xii) separate page groups by a comma if the article was published in discontinuous pages; (xiii) indicate the number of a given edition of a book or manual, e.g., “2ed”; (xiv) for books and manuals, indicate the publisher or editorial office before the main locality of the publisher or editorial office; (xv) separate publishers or editorial offices from locality with a comma; and (xvi) in such cases, name city, state and/or province and country.
