Photoperiodism is the response to the length of the day that enables living organisms to adapt to seasonal changes in their environment as well as latitudinal variation. As such, it is one of the most significant andcomplex aspects of the interaction between plants and their environment and is a major factor controlling their growth and development. As the new and powerful technologies of molecular genetics are brought to bear on photoperiodism, it becomes particularly important to place new work in the context of the considerable amount of physiological information which already exists on the subject. This innovative book will be of interest to a wide range of plant scientists, from those interested in fundamental plant physiology and molecular biology to agronomists and crop physiologists. Provides a self-sufficient account of all the important subjects and key literature references for photoperiodism Includes research of the last twenty years since the publication of the First Edition Includes details of molecular genetic techniques brought to bear on photoperiodism

Life evolves in a cyclic environment, and to be successful, organisms must adapt not only to their spatial habitat, but also to their temporal habitat. How do plants and animals determine the time of year so they can anticipate seasonal changes in their habitats? In most cases, day length, or photoperiod, acts as the principal external cue for determining seasonal activity. For organisms not living at the bottom of the ocean or deep in a cave, day follows night, and the length of the day changes predictably throughout the year. These changes in photoperiod provide the most accurate signal for predicting upcoming seasonal conditions. Measuring day length allows plants and animals to anticipate and adapt to seasonal changes in their environments in order to optimally time key developmental events including seasonal growth and flowering of plants, annual bouts of reproduction, dormancy and migration in insects, and the collapse and regrowth of the reproductive system that drives breeding seasons in mammals and birds. Although research on photoperiodic time measurement originally integrated work on plants and animals, recent work has focused more narrowly and separately on plants, invertebrates, or vertebrates. As the fields have become more specialized there has been less interaction across the broader field of photoperiodism. As a result, researchers in each area often needlessly repeat both theoretical and experimental work. For example, understanding that there are genetically distinct morphs among species that, depending on latitude, respond to different critical photoperiods was discovered separately in plants, invertebrates, and vertebrates over the course of 20 years. However, over the past decade, intense work on daily and seasonal rhythms in fruit flies, mustard plants, and hamsters and mice, has led to remarkable progress in understanding the phenomenology, as well as the molecular and genetic mechanisms underlying circadian rhythms and clocks. This book was developed to further this type of cooperation among scientists from all related disciplines. It brings together leading researchers working on photoperiodic timing of seasonal adaptations in plants, invertebrates, and vertebrates. Each of its three sections begins with an introduction by the section editor, and at the end of the book, the section editors present a synthesis of common themes in photoperiodism, as well as discuss similarities and differences in approaches to the study of photoperiodism, and future directions for research on photoperiodic time measurement.

Photoperiodism and vernalization are fascinating areas in plant physiology. The phenomena were conceived as the expedients to switch on flowering in plants but with passage of time, divulged intricacies establishing as exponents to a wider range of functional processes in them. Despite much of the complexities on the living processes in plants have been discovered by delving into these areas, much remains to be unravelled. The present title has brought forward the diverse features of these disciplines to the students and buding scientists of plant physiology in a simplified form to arouse their interest and gain ground for deeper understanding into these spheres. Contents Part I: Photoperiodism Chapter 1: Physical Aspects of Light and its Role in Plants; Physical aspect of light; How light affect plants; Chapter 2: Photoperiodism; Historical aspects; Definition and concept; Photoperiodic groups of plants; Maturity of plants for photoperiodic responses; Requirement of the number of photo inductive cycles; Photoperiodic induction; Site of perception of photoperiodic stimulus; Role of dark and light periods in photoperodic cycles; Role of light quality and phytochrome; Time measurement by plants; Mechanism of photoperiodism; Genetic approach of photoperiodic response in plants; Photoperiodic effects other than flowering; Practical utilization of photoperiodism; Review of terminology. Part II: Vernalization Chapter 1: Physical Aspects of Heat and its Role in Plants; Physical aspect of heat; How heat affect plants; Chapter 2: Vernalization; Historical aspect; Definition and concept; Quantitative and qualitative responses; Examples of vernalizable seeds and plants; Site of perception of vernalization stimulus; Maturity factor in vernalization; Technique of vernalization of seeds and other plant parts; Induction of vernalization effect; Reversibility of vernalization response; Mechanism of vernalization; Genetic approach of vernalization; Practical utilization of vernalization; Relationship between vernalization and photoperiodism.

Biological Rhythms and Photoperiodism in Plants brings together disparate subject areas into one accessible text of interest to all plant biologists. In this comprehensive volume, leading international researchers review our current understanding of circadian rhythms from a broad perspective. The book begins with a description of well known rhythmic processes such as gene expression, stomatal guard cell opening, and the movement of petals and leaves. Photoperiodic responses such as dormancy, bulbing, tuberization and flowering are then discussed in terms of their rhythmic behaviour. The latest data from current studies with mutant and transgenic plants is also included.
