PREFACE
There has been a welcome extension of the use of physical techniques in the
investigation of biological problems in recent years. This development does
however have its dangers, on the one hand the biologist with a limited physical
background is inclined to take the findings on trust whilst many physicists who
turn to biology take insufficient account of the state of the material which they
are studying. In the first article in this volume G. Harnischfeger provides a
valuable article which should help to meet this sort of difficulty in respect of
low-temperature fluorescence studies in photosynthesis. The physical background
is clearly presented and the problems of low-temperature artefacts are
explored.
Progress with respect to the mechanisms of action of plant hormones has
lagged far behind that of comparable studies with animals. The work of Hertel
and colleagues in Germany and Venis in England has been prominent in
rectifying this situation during the past five years. In this volume Venis surveys
recent progress in this field and considers some of the requirements for rigorous
work on this subject.
Most studies in the evolution of land floras are inevitably concerned with
detailed anatomical descriptions and comparative studies from the fragmentary
fossil record. It is comparatively rare however for a plant physiologist to address
himself to this subject; J. Raven attempts this task in the present volume, by
considering the constraints imposed on the long distance transport systems of
plants in the course of adaptation to the terrestial environment. By bringing
together information from physics, plant anatomy and the earth sciences Raven
challenges palaeobotanists to take a wider view in the interpretation of the
material which they describe.
A consideration of recent progress in the study of tile biosynthesis of plant
cell walls is given by D. G. Robinson; this subject assumes increasing importance
for plant pathologists and botanists concerned with problems of growth at the
cellular level.
I am indebted to the authors of the chapters in this volume for the care which
they have taken in their work which has lightened the editorial task. I am greatly
indebted to Mrs. J. Long for preparation of the Subject Index and Miss Jean
Denison for Secretarial Assistance.
