Main research activities

As the founder of the department of Ornamental Horticulture in the Hebrew University, I devoted a great deal of research on all aspects of growth, development and physiology of  many florist crops as a basic for the development and advancement of the floriculture industry in Israel. The interest in advancing floriculture leads to concentrating in 3 major fundamental lines on research, for which our group is considered as one of the leading in the world (see the 3 representative publications):

The physiology of flowering. We have studied the flowering physiology of many crops and developed ways to control and time their flowering. We have demonstrated the involvement of cytosolic calcium and pH in the photoperiodic induction of flowering, in addition to the effect of auxin, gibberellin and carbohydrates. The six-volume book “Handbook of Flowering” is the most comprehensive treatise published to date on flowering. We have recently started working on the second edition of the book.

Senescence and postharvest physiology of flowering. We have evaluated the physiological and molecular background of flower senescence, including the involvement of flower hormones, carbohydrates and water supply. We have emphasized the importance  of the sensitivity to ethylene as a major factor controlling senescence of several flowers. We have published the first comprehensive review on this subject (1979, 1981), and started working on an updated version of this review, which is still the only comprehensive review available. In the course of work on the subject, we have developed specific original techniques for handling the various cut features, which are new applied commercially in Israel and abroad.

Development of new floriculture crops. Novelty is an important quality parameter of floriculture. It is important to introduce and develop new crops. Some of the plants will have introduced and developed became major commercial crops such as Gypsophila and wax flower (Chanacleucium). We are currently working on introduction of several crops including peony and rice flower. Developing a new crop involves many research aspects from the search of plant material, selection, propagation, growth and flowering control to postharvest handling and marketing.
