Dedication
Advances in horticultural technology are made in small increments.
They come about when researchers have a clear goal in mind and back
their ideas with persistent effort and high-quality, creative research
that seeks answers to both applied and fundamental problems. The
career of Dr. Abraham H. Halevy testifies to the efficacy of this method.
His goal has been no less than the creation of a new industry for his
country. This has been accomplished through unrelenting effort. His
career comprises significant contributions to horticulture in general and
to floriculture in particular.
Born on July 17, 1927, in Tel Aviv, Israel, Dr. Halevy received the
MS and PhD at the Hebrew University of Jerusalem. Although his
doctorate research was in citriculture, he felt that Israel could prosper
growing flowers for export because of its favorable climate and the
availability of educated growers who could easily adjust to the technical
expertise required in floriculture. Thus in 1958 he accepted a postdoctor-
ate research fellowship with the Department of Agriculture at
US.
Beltsville, Maryland, and returned to the Hebrew University the follow-
ing year to found and chair the new Department of Floriculture. Dr.
Halevy was both father and mother to the Israeli floricultural industry,
which now exports millions of dollars worth of cut flowers to Europe and
the United States. He conceived the concept, provided scientific under-
pinnings through his research, nursed the industry in its infancy, and
nurtured a majority of its present teachers and extension workers. The
entire faculty in his department consists of his former students.
His research interests in floriculture cover a wide spectrum of activi-
ties. He is involved in the introduction of new species, new cultural
systems, and the development of new handling and shipping proce-
dures. He has developed petals as a model system for the study of
senescence, and has been a leader in extending vase-life of cut flowers
through bud cutting, sucrose pulsing, and opening solutions. This re-
