2002 OSU/OFA POINSETTIA
TRIAL RESULTS

In this issue we present the results of the evaluations done by growers . These trials were held December 10 at Diefenbacher's Greenhouse in Cincinnati; December 12 at Dill's Greenhouse in Columbus; December 13 at Bostdorff Greenhouse Acres in Bowling Green and on the same day at Barco and Sons Inc. in Medina. More than 80 growers, sales reps, and others turned out for the five evaluations. This report will focus only on the 66 growers who participated.

The setup was similar to that described already for the consumer evaluation in Part I, except that only one plant of each cultivar was presented for evaluation. They were numbered and placed on a bench in random order with enough space given to each plant that they could be considered individually. As in the consumer evaluation, we asked growers to rate the individual cultivars on overall appeal on a 5-point scale with "5" being the top score. We also asked growers to tell us which cultivars (if any, up to 3 cultivars) they would try in their greenhouses next year because of this year's trial.

The results of the grower trial are presented in ( Table 1 ). Because growing conditions differed to some degree among the five facilities, summary grower response data is presented for each location.

Acknowledgments: In addition to the breeders/suppliers, we would like to thank Terry Diefenbacher, The Barco family, Jerry Dill, and Richard Bostdorff and his family for the time and resources shared with us in producing the poinsettias. We thank David Snodgrass at The Ohio State University who made crucial contributions in data collection and care of the plants at the University. Thank you also to the OFA Grower Extension Committee for their involvement in conceiving, organizing, and sponsoring the trial.
