JOP authors instruction

All papers are eligible for publication in the JOP if a suitable manuscript is prepared according to this JOP Authors Guide. The chief in editor will send the manuscript to the Editorial Board for reviewing.

Language: English is the official language of JOP. The Iranian authors should be prepared an abstract as Persian language.

Units: Use the metric system exclusively. Use abbreviation L for liter, mg/L for milligram  per liter, ml for milliliter, and t for tone (metric ton). SI units can be used where appropriate.

Font and Type Size: Use Times New Roman font exclusively. Titles are printed in 14 point but the rest of the manuscript, including tables should be 12 point. When italic typeface is required use italic type, not underline.

Plant Names: Scientific names are to be included for all plant species and are to be in italic font except for the abbreviations which indicate rank at infraspecific level (e.g., Cedrus libani subsp. atlantica, Phytophthora parasitica var. nicotianae). Author citation should only be used when helpful for historical or taxonomic reasons, and then it should only be used when the name is first mentioned in the body of the text (do not use author citation in the abstract or title). Author names are abbreviated in accordance with the international standard provided by Brummitt, R.K., and Powell, C.E., Authors of Plant Names, Royal Botanic Gardens, Kew 1992.

Common names may be used for well-known plants once the scientific name has been provided (e.g., apple, pear, potato, rose, tomato). Cultivated varieties which are the product of selection and/or breeding are to be referred to as cultivars and not varieties. Cultivar names are to be written in accordance with the International Code of Nomenclature for Cultivated Plants. In particular, the part of a name which denotes the cultivar is it be placed within single quotation marks. The abbreviation cv is not to be used within a name (e.g., Malus domestica Golden Delicious, not Malus domestica cv. Golden Delicious). If indicating hybrid status, the multiplication symbol should be used before the name of the genus or the species epithet as appropriate (e.g., Cupressocyparis leylandii, Mentha piperita), or within the formula denoting the hybrid (e.g., Mentha aquatic M. spicata). If the multiplication symbol is not available in your font set, use the letter in lower case, but leave a space between it and the word to which it should be applied (e.g., x Cupressocyparis leylandii, Mentha x piperita). Neither the multiplication symbol nor the letter are to be in italics. Use the letter to indicate a cross such as red x yellow and for the term by in measurements (2 cm x 4 cm). Use italic n and x when indicating sporophytic or basic chromosome number (e.g., 2n=4x = 48).

Headings Ranks and Format: Papers contain one to four headings, all aligned at the left hand margin, as follows:

Rank one: Use boldface and all capital letters. Use a space before this rank but subsequent paragraph (s) continue without a space. Subsequent paragraphs within this section are indented without spaces between paragraphs. Headings such as:







are Rank one headings. Do not use a period after this heading. Rank two This heading subdivides Rank one headings, thus there must be at least two or more Rank two subheads. Titles are boldface with the first letter of important words in capital letters and the others in lower case. Rank two headings are separated by a space above the heading as in Rank one headings. No period after Rank two headings. The paragraph starts on the first line after the Rank two heading and is indented. Rank three: This heading may be used to divide Rank two headings. Initiate this heading with Arabic numerals (1, 2, 3 etc.). With numbers and title in boldface with the beginning of each word in capital letters. The subheading ends with a period. The paragraph continues on the same line. Do not separate this heading with blank lines. Rank four: This heading subdividing Rank three headings will be used rarely. Align left, end with a period, and continue on same line. The font is italic, non-boldface, with the beginning of each word in capital letters. Do not separate with blank lines.

Paper: For A4 size paper this printable area is obtained by entering following margin settings in the "page set-up" of your word-processor: top: 2.7 cm (1.06") ; bottom: 3.5 cm (1.38") ; left: 2.8 cm (1.10"); right: 2.9 cm (1.14").

Spacing and indentations: The final text should be single spaced but a double spaced manuscript may be submitted for editing by the chief in editor. Titles of subheadings should not be underlined. Text should be "justified" in order to fill the entire printable area. Provide a hanging indent (0.6 cm) on the second line of the Keywords and Literature Cited references. First lines of all paragraphs should have a 1.25 cm indentation except those that immediately follow rank three and rank four subheadings. Do not include blank lines between paragraphs within a section.

Organization of a research paper

Title: Titles are printed in boldface in 14 point type. Use capital and lower case for the first word in the titles except for articles ("a" and "the"), prepositions ("of," "in" "on." "during," "between"), and conjunctions ("and" and "but"), except when they are the first word. Gene symbols, which normally begin with lower case letters are not capitalized in titles nor is the first word of specific epithets in binomials. Do not include authorities for binomials in titles. Keep titles as concise as possible. Binomials will be in boldface Italics.

Bylines: The byline under the title includes the name of author(s) (without titles) and affiliations. The given name of authors should be written out in full. The family name is always presented after the given name.The affiliation or address of author is included below the names. The address of the author should be in English.

Abstract: An abstract in English, limited to 200-300 words in a single paragraph. Indent the first line of the abstract. The abstract should contain a concise but comprehensive statement of the problem and results. The Iranian authors should be prepared an abstract as Persian Language. Keywords List five to seven key words not used in the title, preferably.

Introduction: This should include a statement of the problem, a brief survey of previous work, and the scope and purpose of the investigation. References to previous work should be included.

Materials and methods (Experimental procedures): This section should be included in papers describing experiments but may not be required in review papers. Describe concisely the plant materials, the growing technique, methods used, and lay-out of experiments. Include the name of all chemicals and compounds. An indication of the statistical methods used to analyze data should be included.

Results and discussion: This is the heart of the paper. The section(s) may either be presented as a single section or divided into separate Results and Discussion sections. If separate, describe experimental results in the Results section and reserve interpretations, speculations, and conclusions for the Discussion section. At the end of the paper attempt to answer questions formulated in the introduction and conclude with a summary of results and an assessment of future research or prospects.

Acknowledgment: This is reserved for journal paper numbers, source of funding, and name of project, if required. Acknowledgement of help from colleagues or professional associates is appropriate but avoid acknowledgement of routine secretarial help or family members.

Citations and literature cited

Citations to references in the text are listed chronologically surrounded by parentheses with the following format: (Peters, 1950; Jones and Smith, 1990; Brown et al., 1999a). If there are two authors with the same name that have published in the same year, initials may be used to avoid confusion. Note: "et al." is used for three or more authors. Citations to personal communications include the surname or initials of the person and are only to be included within the text, not in the Literature Cited section. The date is optional. Thus: (A.B. Peters, pers. commun.) or (A.B. Peters, pers. commun., 2001). Consider Literature Cited as a Rank 2 heading,. Literature cited should only include references used in the paper. List the authors in alphabetical order, letter by letter, and in chronological order for publications of the same author(s). Do not use a comma before "and" after the penultimate author. Do not use an issue number if the journal uses consecutive numbers for each volume. In the format that follows, note that in all cases the given name or initials follow the family name.

Tables and Figures: Tables and figures are normally included in the text of article (appropriate part). Captions are provided directly above each table and below each figure with hanging indents. They are numbered consecutively with Arabic numbers, and aligned with the width of the Table or Figure, or to the full width of the page if the figure or table occupies more than half of the width of the page. Thus, Table 1, Table 2 etc. and Fig. 1, Fig. 2. etc. If the table or figure is not original, give the source at the end of the caption, e.g. Source: Jones et al., 2001.

1. Tables: Use tables sparingly. Titles of tables go above the table. Place all headings to the center of their column. The size of the table should not exceed the standard page width and length, but tables may be placed portrait or landscape format. Solid lines are used in the heading and in the bottom of the table. The units of the data must be indicated in parentheses in the table headings. If table footnotes are needed, use superscript Arabic numbers 1, 2, 3, etc. The sources of tables should be in the caption.

Proper format for tables JOP should include 4 parts: (1) caption, (2) masthead, (3) body, and (4) footnotes.

  • Caption: The caption should be understandable without recourse to the paper itself. The caption has only the first word capitalized (except for proper names) and ends in a period. The caption may be more than a single sentence. The source of the table, if necessary to include, is indicated in the caption.

  • Masthead: In general, tables are best read up and down. Each column of the table must be explained by a masthead heading. The masthead is enclosed top and bottom by two lines extending to the each edge of the table. Horizontal lines within the masthead can be used to separate groups under a common heading. The units of each column need to be clearly indicated, e.g., No. fruit; Fruit wt. (g); Harvest index (%). Masthead headings should be located on the bottom of the masthead cell.

  • Body: Avoid internal lines in the body of the table. Use rounding to avoid unwarranted precision. Means may be separated by using lower case letters (5% significance) or upper case letters (1% significance). Indicate statistical tests and significance by footnotes, preferably superscript 1, 2, 3, etc. [If letters are used, start at the end of the alphabet (z, y, x, etc.).] The body of the table is enclosed in a line.

  • Footnotes: Footnotes go underneath the body of the table. Put each footnote on a separate line.

2. Figures: Titles of figures go underneath the figure. If a figure is outsized it may be reduced photographically. Be sure to include clear, sharp pictures. Figures, graphs and drawings normally should be all in black and white, not color. Color photographs can only be printed after a special agreement with the chief in editor.
