Seed Functional Ecology Winter School, 2022

The second edition of Seed Functional Ecology School will be held online from 24th to 28th January 2022.

The winter school, which is sponsored by the ISSS, will provide an up-to-date theoretical background and the practical laboratory and statistical skills needed for the measurement, analysis and reporting of seed functional studies linked to three main functions: dispersal, persistence and establishment.

The school aims to educate the next generation of plant ecologists to include regeneration traits in their current and future research, and to facilitate the further development of plant functional trait ecology into new areas.

Registration is open now. Places are limited so early registration is recommended.

To apply and for further information please see the website (http://seedschool.unipv.it/)

Call for abstracts for ISSS 2021


We are pleased to invite you to submit abstracts for presentations at the 13th Triennial ISSS Conference which will be held online on 9-13 August 2021.

The theme of the 13th Triennial Conference is ‘Seed innovation systems for the 21st century’ and the program will cover all aspects of seed science, from the fundamental science underlying seed development, germination, and lifespan through to applied research and the development of cutting-edge technologies that will transform conservation and seed production. Through a series of invited and contributed talks and thematic discussions, this world congress aims to review the current state of the art in seed science and develop a roadmap for priority research in the future.

Abstracts are invited for oral presentations across the five conference themes. Oral presentations will be 12 minutes with 3 minutes for questions. Abstracts not accepted for an oral presentation may be selected for a lightning talk (5 min inc. questions) or poster presentation (format to be confirmed).

The deadline for abstract submission is 28th May 2021.

Further information and guidelines for submission are available here.

If you have any questions please email isss2021@kew.org.

We look forward to receiving your abstract submissions.

Best wishes,

Dr Louise Colville and Prof Hugh W. Pritchard
On behalf of the ISSS 2021 Organising Committee

ISSS 2021 will be online

In the face of continued uncertainty with respect to the COVID pandemic, we have taken the decision to hold the triennial meeting in 2021 online. The meeting will be hosted by Royal Botanic Gardens, Kew on 9 to 13 August 2021. We hope that an online meeting will enable us to engage with a wider audience and look forward to an exciting meeting.

Seed Innovation Systems for the 21st Century

Plenary speakers:

Prof. Richard Ellis, The J. Derek Bewley Career Lecture

Prof. Françoise Corbineau, The J. Derek Bewley Career Lecture

Prof. Gerhard Leubner, The Alfred Mayer Plenary Lecture

Dr Guillaume Née, The Michael Black Founders Lecture



  1. Seed memory – how environment influences traits during development
  2. Seed lifespan – the science of maximising survival
  3. Seed innovation systems for the 21st century (local to global)
  4. Seed form and function – the morphology of success
  5. Seed germination and stress – niches and coping strategies


Each theme will be supported by keynotes, posters, contributed talks and lightning talks. In addition, we will have themed discussions for strategy development on Enhancing lifespan; CWR-NUS; Trait databases; Seeds for use, e.g., restoration.

Papers from the meeting will be published in a special issue of Seed Science Research.

More details, including registration and abstract submission will be available soon.
