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
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. My 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
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.
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
