1999 OSU/OFA POINSETTIA TRIAL RESULTS PART II - Grower Evaluations By Drs. Claudio Pasian (OSU), Stephen Carver (OFA), and Tim Rhodus (OSU)

In this issue, we present the results of four of the five grower evaluations conducted 16, 17, 18, and 19, November, 1999. The growers who grew the plants and generously hosted the open houses were: Lakewood Greenhouse in Toledo, Dill's Greenhouse in Columbus, Barco's in Medina, and Diefenbacher Greenhouse in Cincinnati. Results from Bostdorff Greenhouse Acres in Bowling Green are not reported because of the very low number of growers evaluating plants in this location. Cuttings were donated by four breeders/suppliers: Dummen USA Inc, Paul Ecke Ranch, Fischer USA Inc, and Oglevee Ltd. Each grower followed its own cultural procedures. Planting and pinching were done during a four day window. Plant height (from pot rim) was measured at each location during open houses. We asked growers to evaluate each group of plants (cultivars) using a scale 1 - 5 (1= like the least; 5= like the most). This evaluation is presented in Table 1 below. It is interesting to note how some cultivars fare well, or do poorly regardless of who grew them. Compare this table with Table 1 in last month issue of this newsletter. Worth noticing are differences between what consumers like and would by vs. what growers like. You can check pictures of the cultivars at the following URL: http://flori.ag.ohio-state.edu/~flori/archive/mar00/ptrials1.html
