This conference was the first in recent memory to include all of the major tropical flowers produced and exported on a commercial basis in Hawaii: anthuriums, orchids, protea, and tropicals such as gingers and heliconias. Although each of these major floral groups has its own unique production problems, they face common marketing problems. Thus, marketing of Hawaii flowers was chosen as the unifying focus of the conference. The conference planners and participants believe that through improved and innovative marketing the industry will be able to realize the conference theme, "Growing into the 90's." In addition to marketing issues such as transportation, handling, and market strategies and trends, production problems were also addressed. Concurrent sessions were held so that each floral group could concentrate on the production problems mostrelevant to them. The conference was sponsored by the Cooperative Extension Service, University of Hawaii, the Governors Agriculture Coordinating Committee, and the County of Hawaii, with the cooperation of several floral commodity associations. Thanks are due to the hard-working conference committee members and all of the speakers who participated in this very successful conference· program. Members of the planning committee were: Bernice Berdon, Greg Braun, Mike Crowell, Mike Goldstein, John Halloran, Gerry Hay, Lesley Hill, Karen Hunt, Darrell Kimura, Steven Lee, Ken Leonhardt (Chairman), Harry Lui, Corinne Moniz, Creighton Mow, Tom Nelson,· Kent Pledger, Susan Robertson, Kelvin Sewake, Carol Siebenrock, Jerome Siebenrock, Tosh Sugita, Terry Toki, and Larry Yamamoto.

Rohrbach Hawaii Institute ofTropical Agriculture and Human Resources University ofHawaii at Manoa On behalf of the .Dean of the College of Tropical Agriculture and Human Resources, I welcome you to the Hawaii Cut Flower Industry Conference. I would like particularly to welcome our out-of-state and out-of-country guests. Conferences such as this don't just happen. They require a major effort in planning, time, and resources. The major effort in planning and time has come from your industry organizations and the College of Tropical Agriculture and Human Resources. The major resources are from the Governor's Agriculture Coordinating Committee and the County of Hawaii. I am very pleased to see so many participants, a clear indication of the importance and timeliness of the conference. Your program for the next two to three days focuses on what is happening in the international cut flower industry and on the, current knowledge of production, handling, and marketing of cut flowers. It is hoped that the panel discussions can stimulate some predictions of what will be needed for the industry to continue to grow in the 1990's. I believe that your program also represents and focuses on another important issue that will be critical to the future success ofyour industry. That issue is the ability of several separate commodity groups to work together to reach a common goal and solve common problems. Many of you are aware of the Governor's Agriculture Coordinating Committee's industry analysis program. You are also aware that previous industry analyses have been done on
