Seminars are an opportunity to address special topics attracting a narrow audience. These one-day meetings resemble “mini symposia”, are run by a convener and include invited and offered oral contributions and posters. Participants are welcome to submit abstracts to seminars. Manuscripts presented at seminars may be published in Acta Horticulturae or in Script Horticulturae.
