Speakers instructions

After abstract acceptance, all oral presenters, including invited and keynote speakers, must submit a manuscript for Acta Horticulturae – if this is not agreed to by the author(s), the work can be presented as a poster instead. Authors of posters are welcomed to submit their manuscript for Acta Horticulturae but posters cannot be published as such. Acta Horticulturae (ISSN 0567‐ 7572) is a peer reviewed series, mainly the proceedings of ISHS Symposia and the International Horticultural Congress. All Acta Horticulturae articles are available online at For guidelines and instructions on how to prepare your manuscript for publication in Acta Horticulturae see  ISHS authors guide

Preparing the presentation

  • All oral presentation will be conducted by using a laptop and a LCD projector.
  • Prepare the presentation file with Microsoft PowerPoint 2007 or later versions with extensions *.ppt or *.pptx. Alternatively, you can use the Adobe Acrobat with extension *.pdf. Embedding all fonts in the presentation file is recommended for either case. Overall time slot for each presentation in the oral session is 12 minutes for presentation followed by 3 minutes for discussion. The time slot for keynote speech is 25 minutes for presentation followed by 5 minutes for discussion.
  • Twelve to twenty slides would be enough for good oral presentation. More than thirty slides would not have enough time for presentation (less is better).
  • Prepare your presentation file concisely to appeal for the audience. Typical presentation would consist of following slides in this order:
    • Title, Authors and Affiliations.
    • Speaker name should be highlighted
    • Introduction (background, motivation, purpose of research)
    • Outline of the talk
    • Materials and Methods (assign scientific name for your materials)
    • Results
    • Discussion to wrap up
    • Conclusion and future plan
    • Acknowledgement or else, if required
  • You are the expert on your research, but the audience is not. The well designed introduction is the key for good presentation.
  • Using too small font or showing too many numbers/sentences on a page would make it difficult to understand your excellent work for the audience. Using a font large enough to be seen from the back of the room for carefully selected sentences is preferable (simple is best).
  • Use basic fonts (e.g., Century, Calibri, Arial, New Times Roman) and standard ASCII character set for your presentation. Basic fonts are included on the session PC, but multilingual encoding system and font such as CJK (Chinese/Japanese/Korean) or CJKV fonts are not available. Using multilingual character sets may disturb the structure of sentence. If you are not sure whether using these fonts or character sets in your presentation, embed all fonts in your presentation file and check before the presentation.
  • Approximately 8% of males and 0.5 % of females have some degree of color-vision deficiency. Using minimum and carefully selected colors for your oral presentation would be a good idea to appeal for colorblind audiences. Using colors such as red and green together in your presentation may exclude colorblind members of your audiences.
  • Avoid using dark backgrounds. Dark colored text on a dark colored background is not preferable for a handicapped person, and also for many audiences. Following URL provides a suggestion on color selection for the handicapped person: what colorblind people see
  • For PowerPoint users, try to resist the temptation to use amazing visual or sound effects. These effects often trouble at the discussion.

Bringing your presentation file

  • Save your presentation file in one of the following media:
    • USB flash memory
    • CD/DVD-ROM (certain CD-R or DVD-R media may trouble upon reading the file)
    • USB external disc (FAT32 or NTFS formatted)
    Note: Bringing your own laptop, tablet, smart phone or desktop PC for your presentation are not acceptable to minimize time loss for changing the PC. Any of SD/MD/CF/xD/Memory stick/MMC media is not acceptable, too. Your media and the file should be free of virus infection.
  • The following freely available software will be installed on the session PC:
    • Microsoft PowerPoint
    • Adobe Acrobat Reader
