Oral presentation

Speaker instruction

After abstract acceptance, all oral presenters, including country report, 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 www.actahort.org
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 35 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)


    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.

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

  • Most of the audience are not native speakers of English. All speakers are asked to take it into account to speak at moderate speed.

Student Award

  • For encouraging students to participate and submit the research, during the symposium two student awards will be given from ISHS:

    one award for the best oral presentation given by a student who is in the same time the presenter and first author of the submitted manuscript

    one award for the best poster presented by a student who is first author of the work

    ISHS Student Award winners will be recognized in each symposium report published in the quarterly ISHS membership magazine Chronica Horticulturae, including a photo of the award ceremony or the award winners and a brief outline of the winners. Awardees will be invited to write a summary on their research, to be considered for publication in Chronica Horticulturae. A one-year complimentary membership of the ISHS and a Certificate will be awarded to the winners.
