Science and News
Part of our work at the OHA is to share knowledge and advocate for the industry. One way of doing that is keeping up with current research in the field.
This is merely a snapshot of the vast research being done each year, and we encourage you to dig deeper and do your own research if the science is something you’re interested in.
Some Interesting New Research!
New Hazelnut Research in 2024-25
Surveying the Hormonome of Hazelnut Catkins During Winter Dormancy (PhD Dissertation)
“Deciduous woody perennials, such as hazelnut, undergo winter dormancy to protect sensitive tissues, such as flowers, from harsh conditions. The reproductive success of the tree is dependent on the release of dormancy under favorable conditions. To bloom, the tree must first experience a certain amount of chilling, followed by a certain amount of warmth. With global warming, many trees risk not being able to accumulate enough chilling to release dormancy. Also, when trees accustomed to warm climates are brought into cold climates, they might bloom prematurely and risk freezing damage. The latter is the case for hazelnut, recently adopted as a crop in Ontario, Canada. The present study investigates the hormonal regulation of dormancy in hazelnuts’ male flowers (catkins) by generating hormone profiles in early and late-blooming accessions throughout the dormant season. […] Cumulatively, the present study has generated the most comprehensive hormone profile in dormant flowers of deciduous woody perennials and has identified potential strategies for the delay of bloom in hazelnut catkins through the manipulation of hormones.”
How does harvest time affect the major fatty acids and bioactive
compounds in hazelnut cultivars (Corylus avellana L.)?
“This study was conducted to investigate the effects of harvest time on the protein, oil, fatty acids and bioactive compounds in hazelnut cultivars (Corylus avellana L. cvs. ‘Tombul’, ‘Palaz’, ‘Çakıldak’, ‘Okay 28’ and ‘Allahverdi’)”
