In Memoriam
With the death of Martin Huldrych Zimmermann on March 7, 1984, at the
age of 58, the international community of plant physiology has lost not only
a colleague whose own practical scientific work has played a decisive role in
the development of this field, but also the author and editor of numerous scien
tific works that have greatly served the dissemination of scientific knowledge.
We mourn for a friend, who as long ago as 1974 entrusted a book to us,
(Zimmermann and Brown: "Trees "). On the recent founding of a new book
series (" Springer Series in Wood Science "), Martin H. Zimmermann willingly
contributed his own work as the initial volume ("Xylem Structure and the
Ascent of Sap "). This was to be his last book; the moving epilog - placed
at his own wish at the last moment at the conclusion of the volume - became
also his farewell to active publishing.
Martin H. Zimmermann's main work in the long years of cooperation with
Springer-Verlag was, however, the handbook series "Encyclopedia of Plant
Physiology, New Series". Over more than 12 years of intensive and often labori
ous effort he achieved, together with his editorial colleague, the realization
of a complete survey of plant physiology. All those who experienced personally
with what patience, efficiency, and diplomacy Martin H. Zimmermann not only
planned each volume, but also indefatigably supported the numerous editors
and authors with good counsel and help, will feel, with us, a great debt of
gratitude to him.
The first volume of this series was edited by him jointly with 1.A. Milburn.
Tragically, it was no longer granted to him to see the series brought to its
conclusion.

Foreword
This is the second of the set of three volumes in the Encyclopedia of Plant
Physiology, New Series, that will cover the area of the hormonal regulation
of plant growth and development. The overall plan for the set assumes that
this area of plant physiology is sufficiently mature for a review of current knowl
edge to be organized in terms of unifying principles and processes. Reviews
in the past have generally treated each class of hormone individually, but this
set of volumes is subdivided according to the properties common to all classes.
Such an organization permits the examination of the hypothesis that differing
classes of hormones, acting according to common principles, are determinants
of processes and phases in plant development. Also in keeping with this theme,
a plant hormone is defined as a compound with the properties held in common
by the native members of the recognized classes of hormone.
Current knowledge of the hormonal regulation of plant development is
grouped so that the three volumes consider advancing levels of organizational
complexity, viz: molecular and subcellular; cells, tissues, organs, and the plant
as an organized whole; and the plant in relation to its environment.
The first volume, entitled Molecular Aspects of Plant Hormones and edited
by Professor J. MACMILLAN, was published in 1980. It treated the molecular
and subcellular aspects of hormones and the processes they regulate. Although
it dealt with chemically distinct classes of hormone, the first volume stressed
properties and modes of studying them that were common to all classes.
In the present volume, the roles of hormones at levels of organization from
the cell up to the whole plant are traced. The cellular processes of increase
and change, and the interrelations of cells in tissues, of tissues in organs, and
of organs in the whole plant, are considered in turn. During this progressive
treatment of levels of organization, the relevant basic properties of hormones
are introduced and illustrated.
A third volume addresses the interrelationships of hormones with factors
in the environments of the tissues, the organs and the whole plants, within
which the hormones are functioning. When this volume touches upon wide
reaching topics such as photomorphogenesis or plant movements, only those
aspects that relate to principles of hormonal regulation are treated. Separate
volumes of the Encyclopedia of Plant Physiology, New Series, provide compre
hensive treatment of topics such as photomorphogenesis and plant movements.
My role in the preparation of these volumes has been to propose a theme
and prepare a plan to cover the current status of the field of hormonal regula
tion, then to circumscribe the portions of the plan that form logical volumes.
Thereafter, the editors of the individual volumes have determined the manner
in which the domain for which they accepted responsibility was treated. The
x Foreword
editor of the present volume is Professor TOM K. SCOTT and, in the Introduction
to his volume, he outlines his approach and that of his authors.
The base from which these volumes have developed is the old series of
the Encyclopedia of Plant Physiology. The volumes in the New Series of the
Encyclopedia may, therefore, concentrate on principles that may be derived
from the mass of older information and on the findings of the past 20 years.
The length of each volume has been deliberately restricted, but effective organi
zation of topics and their succinct treatment assures the reader of a concise
but comprehensive statement of current knowledge and thought in the field.
I thank Professor Kenneth V. Thimann for reviewing the theme and initial
plan for these volumes with me.
