Dr. Helga Déri
She has been working at the HáGK (Research Centre for Farm Animal Gene Conservation) and the National Centre for Biodiversity and Gene Conservation since 2018, as research fellow. Her current research field includes the investigation of nectar production and flower histology in melliferous plant species and the study of pollen profile in Hungarian honeys to determine their botanical origin. She participates in the research projects of “Investigation of nectar production in sunflower hybrids” and “Investigation of nectar production in long-flowering and late-flowering Robinia cultivars”. Formerly, she had performed histological examinations on the vegetative organs of desiccation-tolerant plant species. In her doctoral dissertation, she demonstrated the endogenous rhythm of nectar secretion, stamens and pistil, the sugar composition of nectar, and the histological structure of flowers in quince.
