A focus group was conducted to ascertain the attitudes and behaviors of wholesale floriculture greenhouse growers toward the use of computers for marketing purposes. The focus group consisted of nine individuals from nine different wholesale greenhouses in the Greater Cleveland - Lorain area. The greenhouses were selected according to their sizes which ranged from one-half acre of production under cover up to 70 acres. Each individual was either the owner of the greenhouse operation or charged with the marketing function in that company. The study was conducted for the purposes of identifying possible factors related to the speed of adoption of computer technology for marketing purposes and its possible future course within the wholesale greenhouse industry. Variables that were identified from the focus group study were tested using a national survey.

In spite of its rapid growth in recent years, the floricultural industry in Korea is rather small with respect to total acreage and number of growers engaged, product value, international trade, and production facilities and technics involved. The production status will be introduced with slides. Nevertheless, variable climatic conditions of the temperate zone such as the distinctive 4 seasons favor the prosperous growth of a variety of vegetation throughout the Korean peninsular. Thus, it has been wellknown that many ornamental plants native to Korea have good potentials for horticultural use. The morphological characteristics of a few selected plants will be introduced along with slides. These plants include Aster spp, Iris spp, Gentiana soabra, Chrysanthemum zawadski, Pulsatilla koreana, Cymbidium spp, Calanthe spp, Dendrobium moniliforme, Abeliophyllum distichum, Ardisia spp, Hibiscus syriacus, and many others.

Oklahoma floriculture producers, ornamental-horticulture retailers, mass-market retailers, and cut-flower wholesalers were surveyed to compare and contrast the industry in terms of attitudes towards their products and problems. Overall, attitudes of all four segments of the industry were neutral to negative on potted flowering plants, but were positive to neutral on bedding and foliage plants. However, producers were slightly negative concerning the postharvest life of bedding plants. While cut-flower wholesalers had a positive attitude concerning cut flowers, ornamental-horticulture retailers and mass-marketers tended to be neutral to negative. In particular, retailers and mass-marketers believed that cut flowers were too expensive and too short-lived. Floral preservatives were used by 82% of ornamental-horticulture retailers, while only 19% of mass-market retailers used preservatives. All cut-flower wholesalers used preservatives. Capital availability and market demand were the factors most limiting expansion for producers and ornamental-horticulture retailers; whereas mass-market firms listed competition as their most limiting factor.

In an effort to expand and improve the agriculture curriculum, the Georgia Department of Education set standards for new greenhouses to be built at high schools. These modern greenhouses are to serve as teaching facilities for new horticulture classes. However, current teachers had little or no background or experience in teaching greenhouse or nursery management courses. In response to the GDE needs, a summer workshop “Managing Crop Production and Equipment in the School Greenhouse” was held at CAES Griffin Campus and at Pike County High School. Faculty from UGA departments presented topics such as water quality, irrigation and crop nutrition, cultural guidelines for major floricultural crops, IPM, pesticide safety, and marketing, business planning and fund raising. Included in the program were numerous hands-on activities designed to cover the essential practical skills needed for a greenhouse employee—proper handling and planting of plugs, watering, calculating fertilizer rates, fertilizer injector maintenance and calibration, soil pH and fertility monitoring, scouting and pest identification, and proper pesticide handling and spraying techniques. Twenty-two teachers from schools with horticulture curriculum attended the training. The workshop evaluations indicated high satisfaction with the material presented. Teachers pointed out that the practical skills had not only been very useful but also the manner in which they were presented would be easily applicable to students. The knowledge acquired will be incorporated into the fall and spring curriculum. Through the effort of the floriculture specialist, a high-quality educational program was delivered to Georgia High School teachers, which in turn translate into attracting student into joining the growing ornamental horticulture industry.

Floricultural producers, cut flower wholesalers, mass market retailers and general retailers were surveyed to compare and contrast the industry in terms of attitudes and problems. Questions involved general business information, as well as specific crops. Overall, all four segments of the industry were neutral to negative on potted flowering plants, but were positive to neutral on bedding and foliage plants. However, producers were slightly negative concerning the postharvest life of bedding plants. While cut flower wholesalers had a positive attitude concerning cut flowers, retailers and mass marketers tended to be neutral to negative. In particular, retailers and mass marketers felt cut flowers were too expensive and too short lived. Floral preservatives were used by 81.6% of general retailers, while only 18.8% of mass market retailers used preservatives. All cut flower wholesalers used preservatives. Capital availability and market demand were the factors most limiting to expansion for producers and general retailers; mass market firms listed competition as their most limiting factor. Results from other questions will also be provided.

Experiments with' White Christmas' and `Carolyn Wharton' caladiums (Caladium × hortulanum Birdsey), croton (Codiaeum variegatum), brassaia (Brassaia actinophylla Endl.), `Annette Hegg Dark Red' poinsettia (Euphorbia pulcherrima Wind.), and `Super Elfin Red' and `Show Stopper' impatiens [Impatiens wallerana (L.) Hook.f.] determined effectiveness of paclobutrazol in solid spike form as compared to media drench applications for height control. Paclobutrazol drenches and spikes were effective for all crops tested, with a similar concentration response for all, except that drenches had greater efficacy than spikes on caladium. A reduced effect was observed when spikes were placed on the medium surface of `Super Elfin Red' impatiens, while placement in the middle of the pot or around the side was equally effective. These results indicate that the spike formulation of paclobutrazol has potential to provide adequate size control for floriculture crops with the possible exception of rapidly developing crops, such as caladiums. Chemical name used: (2RS, 3RS)-1-(4-chlorophenyl)-4,4-dimethyl-2-1,2,4-triazol-1-yl-) penten-3-ol (paclobutrazol).

Lupinus albus ssp. graecus, L. Fabaceae (Boiss. and Spruner) Franco and P.Silva, is being studied at the TEI of Heraklion since 1998 as a new plant with potential use in floriculture and ornamental horticulture. The plant has been recorded botanically; however, little is known about its physiology and genetic profile. Lupinus albus ssp. is a herbaceous annual plant 10 to 20 cm tall, growing at roadsides, field margins, vineyards, and olive groves up to 700 m altitude. The leaves are 5 to 11 cm wide, palmate shaped in alternate orientation, with five to nine leaflets 10 to 18 mm wide, all arising from the same point. The flowers are borne in terminal or lateral spike-like racemes 10 to 20 cm long. Florets are 15 mm long, dark blue occasionally with a white patch, stamens forming a tube. Pods are 60 to 70 mm long,with four to six black-spotted seeds. In the present work, seed germination studies were conducted combining chilling pretreatments with physical scarification (scratching). Mature seeds chilled at 5 °C for 6 weeks germinated readily (83%) when scarified with sand paper. Furthermore, we tested the effects of several plant growth regulators (chlorocholine chloride, paclobutrazol, maleic hydrazide and Ethrel 48) on young plants of Lupinus in order to obtain compact pot plants with more flowering racemes. Paclobutrazol at 5 and 10 mg/L achieved the best retardation effect, but did not affect flowering. In another trial with different potting media,the commercial potting soil proved the most suitable for growing lupins satisfactorily. It is concluded that Lupinus albus spp. graecus L. need further investigation in order to establish the best cultural conditions for its growth and development. Furthermore, due to its high genetic variability, selection and genetic improvement is required for optimal results.
