During germination, the most resistant stage of the life cycle - the seed - changes to the most sensitive stage, namely the seedling. Therefore, in desert plant species seed dispersal and subsequent germination in the optimum time an place place are particularly critical parameters. Discussed here are the ways and means by which desert plants have adapted through the course of evolution to their extreme environment. Two such strategies which have evolved are a) plants with relatively large and protected seeds which germinate when the chance of seedling survival is high and the risk relatively low or b) those with an opportunistic strategy: minute seeds which germinate after low rainfall under high risk for seedling survival if additional rain does not follow. Most species adopt a combination of the two mechanisms. Species have adapted both genotypically and phenotypically, both aspects of which are also discussed in this thorough text. The reader is provided with a good understanding of the complex influences on each seed traced through from initial development to germination stage regarding germination preparation and subsequent survival.

Annual desert plant species of unrelated taxa in the Negev Desert of Israel have developed complementary sets of adaptations and survival strategies as ecological equivalents with physiological, morphological and anatomical resemblances, in the various stages of their life cycles. After 40 years of research in hot deserts Yitzchak Gutterman provides a comprehensive treatise of such adaptations and strategies. In doing so he covers the following topics: post-maturation primary seed dormancy, which prevents germination of maturing seeds before the summer; seed dispersal mechanisms with escape or protection strategies; cautious or opportunistic germination strategies; seedling drought tolerance. The day-length is an important factor in regulating flowering as well as the phenotypic plasticity of seed germination which is also affected by maternal factors.

The Germination of Seeds, Third Edition discusses topics concerning seed germination. The book is comprised of seven chapters that tackle subjects relating to the field of germination. Chapter 1 discusses the structure of seeds and seedlings, while Chapter 2 covers the chemical composition of seeds. Chapter 3 tackles the factors affecting germination, and Chapter 4 deals with dormancy, germination inhibition, and stimulation. Chapter 5 talks about the metabolism of germinating seeds, and Chapter 6 discusses the effect of germination inhibitors and stimulators on metabolism and their possible regulatory role. Chapter 7 covers the ecology of germination. The book will be of great interest to botanists, who are particularly concerned with plant physiology.
