Cultivars in the study:

Welcome to our Fall 2002 Poinsettia Height Control and Graphical Tracking Site. Each week we will look at the growth of 8 different poinsettia crops growing in our greenhouses at the University of Florida and make height control decisions. We will provide notes each week on how we made the decisions about growth regulator applications. Plant heights are plotted against a graphical tracking curve that provides a general guide to the desired plant heights at different times during production.
For more information about graphical tracking poinsettia heights or to build your own graphs go to http://www.ecke.com/html/h_points/points_tech.html
and look under Graphical Tracking Software. At one point they ask you to select the type of curve you want from "Standard curve" or "Late Curve" for pinched crops. In warm climates, it is better to use "Late Curve."
