Research Reports

Direct Results from AFE-funded Projects

Floriculture and horticulture research reports are finished project summary reports that show the results of the project, its scientific accomplishments and the impact to the industry. All AFE reports are made available to the industry for free.

These reports are mandatory for all projects that have terminated and are due within 30-60 days of the termination of the project. These final research reports are distributed through articles, press releases and alerts to strengthen the industry as a whole and to benefit everyone.

AFE reports are divided into seven categories. Use the filter option below to view reports from each category. You can also use the website search box to search for specific articles.

Researchers must format their reports in a specific template.
