  • Those who do not hold a user account with ISHS yet: create an ISHS user account first. After payment and activation of your user account, you can start your abstract submission.

  • Abstracts must always be submitted by the presenting author, using their own personal ISHS user account. Submitting an abstract on behalf of, or using the ISHS user account of another author is strictly prohibited.

  • Abstracts must be submitted by 1 October 2026 for consideration by the Scientific Committee. Authors will be notified of provisional acceptance of abstracts by 1 November 2026 and will also be notified if the abstract has been selected for an oral or poster presentation.

  • All oral presenters, including invited and keynote speakers, must submit a manuscript for Acta Horticulturae according to the Acta Horticulturae guidelines by 1 February 2027. (Alternatively, presenters have the option to submit a full scientific manuscript on the topic presented at the symposium, for publication in the ISHS Scientific Journal eJHS in lieu of submitting a manuscript for Acta Horticulturae. Papers submitted in this manner will go through the standard procedures for peer-reviewed journal papers.) Oral presenters who fail to submit a manuscript for publication in Acta Horticulturae or the ISHS Scientific Journal may be refused the floor for making their oral presentation. Authors of posters are strongly encouraged to prepare and submit a manuscript for Acta Horticulturae.

  • Presenting authors of abstracts accepted for presentation (both oral/poster) must register for the symposium by 1 February 2027. Failing to register for the symposium will result in your abstract being withdrawn from the symposium program and your manuscript being withdrawn from the Acta Horticulturae symposium proceedings.
