IOS Webinar #12: Flower Development and Diversity in Quercus, and Improved Methods for Rooting Cuttings of Evergreen Oaks

Event Date: 
Thursday, 28 May 2026

The IOS is pleased to announce our next virtual event, again co-hosted with the Global Conservation Consortium for Oak (GCCO), which will take place over Zoom at 10 am US Central Time on May 28, 2026

In this webinar, we will first hear from Hugo Afonso, PhD Student at the Centre of Molecular and Environmental Biology (CBMA), University of Minho, Portugal, and Biopolis/CIBIO-InBIO. His presentation will summarize recent advances in understanding the molecular processes that regulate the reproductive phenology of Quercus, highlighting the role of floral separation and diversification in shifting pollination dynamics and reproductive fitness.

During the second part of the webinar, Greg Tyler, calculus teacher at Central Catholic High School, Portland, Oregon, USA, will discuss protocols he has developed for rooting cuttings of evergreen oaks. Following the presentations, there will be Q&A.
