Book Description
COMPARATIVE EMBRYOLOGY OF ANGIOSPERMS is a review of the developmental processes leading to sexual reproduction in flowering plants. On the basis of embryological data and certain evidences from other areas of study, it lays special emphasis on the relationship among and within the families and orders of angiosperms. Occasionally, inaccuracies in observation and interpretation are pointed out, alternative interpretations offered, gaps in our knowledge highlighted, and prospects outlined. The text is documented with 36 tables, 376 figures, and about 5000 literature citations, which contribute to making this book comprehensive. Besides students and research workers interested in angiosperm embyology, taxonomists, plant breeders, agriculturists, and horticulturists will also find much useful information in this treatise.

Book Description
The book is divided into three parts: Flower, Anther, and Ovule. The principal aim of this volume (along with the other 3 volumes in the series) is to summarize the classical and current concepts about flower generative organs, their structure and development, and about seed formation processes. The book contains ample material that can be employed

Book Description
This volume covers up-to-date notions of seed structure, processes resulting to its formation (syngamy, triple fusion etc.), as well as of postseminal development (seed dormancy and germination). Great attention has been paid to the morphological and functional aspects of fertilization process and embryo- and endospermogenesis.

Book Description
Plant embryology, dealing with the regularities of initiation and the first stages of development of an organism, is now flourishing because of the overall progress being made in natural sciences. Such discoveries of the 20th century as production of plants from a single somatic cell, experimental haploidy, and parasexual hybridization were of general biological significance. The combined efforts of embryologists, geneticists and molecular biologists yielded the discovery of specific genes that control meiosis, egg cell development and early stages of embryogenesis. The tendency to synthesize data of embryology and genetics has become increasingly noticeable. It is connected with the fact that the majority of problems connected with morphogenesis, such as differentiation, specialization, the evaluation of features and the definition of the notionsgene and feature andgenotype and phenotype concern embryology and genetics (embryogenetics) in one way or another. Evolutionary embryology has given rise to a new approach to the study of problems of adaptation in plants. In connection with the problem of preserving biological diversity under conditions of ecological stress, special attention is paid to ecological embryology, revealing the critical periods in early ontogenesis and plasticity and tolerance of reproductive systems at the level of species and population. The study of variability of morphogenesis and phenotype in population (life cycle variations and the diversity of reproductive systems) is the most important point in the population embryology of plants.

Book Description
This book is designed to introduce the basics of different aspects of the biology of reproduction in a concise and coherent manner. The book aims to equip students with the fundamentals of the biology of reproduction and also update them with the most recent advances in the field of reproduction. The book has been organized into 16 chapters that introduce and explain different aspects in a stimulating manner. Each chapter is supplemented with a summary and relevant illustrations. A glossary has been added to help the students to understand some important scientific terms. The book offers comprehensive coverage of the important topics including: Flower structure and development Development and structure of male and female gametophytes Pollination biology, fertilization and self-incompatibility Endosperm, embryo and polyembryony Apomixis and seed biology A separate topic on experimental plant reproductive biology (experimental embryology) has been provided, which includes basics of cell, tissue and organ culture, anther culture, pollen culture, flower, ovary, ovule culture, embryo culture, somatic embryogenesis, synthetic seeds, protoplast culture and other aspects of plant biotechnology. The book aims to cater to the needs of the advanced undergraduate and post-graduate students in Botany, Forestry, Agriculture and related fields.

Book Description
Modern angiosperm taxonomy or systematics provides a strong foundation for the progress of biological sciences as it incorporates studies on biosystematics, chemical and serological evidences, numerical taxonomy, cytogenetical and ecological evidences and many others. This book accounts for information on classical and fundamental aspects of taxonomy as well as its recent developments. Special attention has been paid to the chapters on origin of Angiosperms, Theory of Evolution and Evolutionary trends in Angiosperm Flowers. The International Code of Botanical Nomenclature, Important herbaria, Techniques for the preparation, storage and study of herbarium specimens, Botanical gardens, and Taxonomic literature are discussed in detail and includes the study of some selected families belonging to 21 orders. For each family, general features and evidence from anatomical, embryological, chromosome numbers and phytochemical data have been added and evolutionary trends discussed. Attention has also been drawn to economic importance and geographical distribution of these families. Illustrations for some members of these families have also been added.

Book Description
Jatropha curcas or Physic Nut is a small tree (bush plant) that produces fruits under tropical climate. The fruits contained seed that are ~40% oil rich. This oil is excellent for biodiesel. The bush is a now new coming crop because it may cope with harsh environmental conditions such as semi-aridity and poor land. It is considered as one alternative for climate mitigation that does not compete with arable land normally dedicated to food crop and can be used to regain degraded land or fight desertification. This bush has been considered seriously by the international community only recently (~2006-2008), but worldwide scientists did an outstanding job to drawn Jatropha out of its semi-wild status and bring it on the industrial scene. Problems remains, but we have now a comprehensive picture of this crop and almost every technological challenged were addressed. From now, the job will have to concentrate on breeding in order to domesticate this species. Therefore, it is the right time to sum up worldwide contributions in a comprehensive book with a breeding looking to improve the chance of this plant to stabilize as a crop and to fulfil with the expectations that humans invested in it. A book with this perspective will help international community to give a step on. The book will be a broad and comprehensive look on Jatropha until the details since the book is being contributed by international experts worldwide that have already published works in the international press of Science. Illustrations, tables geographic maps, GPS location, etc are added by each contributors according to the feeling they have concerning what they think their contribution should be.

Book Description
Thirty-four years have elapsed since the publication of the late Professor P. Maheshwari's text, An Introduction to the Embryology of Angiosperms, a work which for many years served as an invaluable guide for students and a rich source book for research workerso Various texts dealing with sections of the braad spectrum oftopics encompassed by Maheshwari in his book have appeared in the interim, but a compendious modem work dealing with the whole field has been lacking. This present volume splendidly meets the need, and it is altogether fitting that Professor B. M. lohri, long an associate and close colleague of Professor Maheshwari and himself a prolific contributor to the subject, should have undertaken the task of editing it. When Maheshwari wrote, it was stiIl feasible for one author to handIe the subject, but today even someone with his fine bread th of vision and depth of understanding could not, alone, do it justice. So the effort has to be a collaborative one; and Professor lohri's achievement has been to bring together a team of authoritative collaborators, assign them their responsibilities, and put them to work to produce a text as integrated in its treatment as the diversity of the subject would allow. The product vividly illustrates the advances that have been made in the study of angiosperm reproductive systems in the last 30 years, and the book is surely destined to become the new standard for student and researcher alike.
