Technology Transfer

The Floral & Nursery Plants Research Unit conducts research that addresses the needs of the Floraculture industry.  To do this, FNPRU scientists regularly interact with growers, nurseries, diagnostic laboratories, grower associations (especially the Society of American Florists and American Nursery and landscape Association), fellow scientists, as well as regulatory and action agencies.  These interactions often lead to collaborations and research support.  While the majority of customers are non-governmental, FNPRU also seeks collaborations with the agricultural community and scientists from universities, industry and international agencies.
