Section Ornamental Plants Eighth Int’l Protea Research Symposium A California flower farm is the backdrop for an international group photo on the tour. Protea researchers and growers from throughout the world held joint meetings organized by the California Protea Association, of the ISHS Working Group on Protea and the International Protea Association in southern California during spring 2006. Topics of key research and interest included Hybridization & Selection, Plantation Management Practices and Nursery Production. Outside tours of California protea nurseries, flower farms and wholesale floral shippers were combined with formal research presentations in a classroom setting. The greatest share of research presentations was in the field of hybridization and indicates the current level of development the protea industry has attained. New products and the methods of developing and identifying these new floral and horticultural products have Protea hybrid “Frosted Fire” displays superior hybrid characteristics of rich color, glossy texture and white pubescent bracts. taken this industry from a wildflower harvest into the beginning of manipulation of the bloom season, vase life and color palette of hybrid material. Some management practices that were researched and presented included beneficial insect trials (Leandro), minimum water requirements (Silber), and levels and timing of nutritional feeding (Moore-Gordon). Superior material, maintained with eco-friendly methods, is a great development toward sustainable protea plantations worldwide. Another facet of hybridization and selection reported in the research was the success of protea in environments that were thought to be unsuitable for protea flower production. Hot tropical environments were not thought to be ideal for the Mediterranean climate indigenous proteas, but in both Hawaii (Leonhardt) and Africa (Percival) trials of plant material showed success with protea selections. These trials even indicated preferred genetic lines for continued research and hybridization. This success brings the possible development of farms in some cash strapped, underdeveloped regions of the tropics. Previous symposia examined how to grow proteas in marginal conditions. In 2006 the trial results of the increasing pool of genetic material provided another tool to expand into different environmental growing regions. Both South African and Australian native proteas were the subject of hybridization presentations and a new potential cutflower selection adaptable to conditions in Portugal was introduced Protea Hybrid “EP1999”. Attendees examine grafted Banksia on the grower tour (B. hookeriana on B. integrifolia). The Symposium Opening Address was given by Audrey Gerber “Contributions of Research to the Evolution of the Protea Industry” and gave a historical look at the focus of research during the previous seven symposia. Her presentation explored the response of research to “the problems of the day” throughout the short history of our developing protea industry (1970s - 2006). Poster topics included fertigation, and hybridization/selection. Oral Sessions were Crop Management, Pest and Disease, Propagation, and Hybridization/Selection. Future symposia are considered for South Africa in 2008 and Portugal in 2010 where the emphasis on research for hybridization and selection of superior material is bound to be of major interest.

Section Vegetables Sixth Int’l Symposium on Artichoke, Cardoon and Their Wild Relatives Participants of the Symposium. The VI International Symposium on Artichoke, Cardoon and Their Wild Relatives was held in Lorca (Murcia, Spain) on 28-31 March 2006. The event was organized by the Technical University of Cartagena (UPCT) and the Murcian Institute of Research and Agri-food Development (IMIDA). Dr. Juan A. Fernández and Ir. Regino Aragón organized and convened the Symposium. More than 120 participants from 12 countries attended 35 oral and 45 poster presentations. The Symposium focused on eight topics, namely, Plant Material, Breeding and Biotechnology, Crop Physiology, Production Authors of this summary report, Drs. Juan Fernández and Daniel Leskovar. Participants in the Centro Integrado de Formación y Experiencias Agrarias, Lorca. Technology, Water and Nutrient Management, Crop Protection, Post-harvest Technology, Product Quality and Marketing and Consumption. A round table discussion with key representatives from the artichoke fresh market and processing industry, production and research sectors addressed critical issues on consumption and marketing. In addition, a technical all-day tour included visits to main artichoke field cultivation areas, fresh-market and processing facilities of the Lorca Region. The Mediterranean Basin produces more than 80% of the total world production of artichokes, which represents 65.8% for the EU. The principal producing country is Italy, followed by Spain, Argentina, Egypt and France. CHRONICA HORTICULTURAE •VOL 46 • NUMBER 4 • 2006 • 37
