PREFACE
This book brings together various topics concerning the diseases of
harvested fruits and vegetables. A considerable part of the material on
which this book is based has been gathered from my lectures given to
students at the Hebrew University of Jerusalem, at the Faculty of
Agriculture in Rehovot. The material has generally been based on
original articles and reviews written by scientists from all over the world.
Throughout the book I have tried to impart to the reader an awareness
of the great variety of research that has been constantly done in the field
of postharvest pathology. Among the studies done in the field, some
research has made a significant and exciting contribution to the
understanding of the inter-relationships between the pathogen and the
harvested fruits or vegetables. Throughout the years, with the
advancement in this research, the challenge to integrate the ultimate
aim - the lengthening of the postharvest life of fruits and vegetables -
with an understanding of the biochemical processes that enable us to do
just that, has become most prominent.
Although each chapter in the book constitutes a separate unit, the
order and continuity of the chapters are relevant to a better
understanding of the whole subject.
The first four chapters describe the causal agents of postharvest
diseases of fruits and vegetables, their sources and their ways of
penetration into the host, factors that may accelerate the development of
the pathogen in the host - and those that suppress them. A list of the
main pathogens of fruits and vegetables, their hosts and the diseases
elicited by them are given in a separate chapter, while a detailed
description of the major diseases of selected groups of fruits - subtropical
and tropical fruits, pome and stone fruits, soft fruits and berries, and
solanaceous vegetable fruits - is given at the end of the book, in the
Summary of Postharvest Diseases of Four Groups of Fruits.
Chapters five and six focus on the attack mechanisms that the pathogen
may use to invade the plant tissues and develop within them, and the
defense mechanisms with which the host is equipped to stop invaders or to
suppress their development. Physiological and biochemical changes
following infection are described in Chapter seven. The following chapters,
8 to 12, all deal with treatments aimed at suppressing postharvest diseases.
While chapter 8 describes treatments for maintaining the natural
