DIF and Graphical Tracking
Welcome to the American Floral Endowment's Grow Pro Webinar Series! Throughout this series, our nationally recognized researchers, hosts, and speakers will offer ‘how-to’ advice based on AFE-funded and other research projects to help the industry navigate through these ever-changing growing challenges. The webinar topics are current and offer long-term opportunities for growers to focus on increased profit, greater sustainability, and improved labor efficiency. Each session includes a presentation and interactive Q&A. To see the full series calendar visit endowment.org/GrowPro.

The August 23rd session of our series focuses on DIF and graphical tracking.

Commercial poinsettia buyers place tight restrictions on poinsettia height and width. Additionally, they expect uniformity for all varieties and container sizes. Precision control of poinsettia height can be accomplished with plant growth regulators or altering the day and night temperatures during crop development or a combination of both methods. Dr. Heins will provide guidance in use of day/night temperature to control height and graphical tracking to guide the temperature changes necessary throughout the crop.

Topics Include:
• Guidelines for use of graphical tracking and DIF for height control
• The use of a combined program of PGR’s and DIF for height control
• The value of graphical tracking
• Guidelines for selection of plants for graphical tracking
