The Study Of Bryophytes Is No Longer Confined To Their Morphology, Anatomy, Life-History, And Phylogenetic Considerations. In Recent Years There Has Been An Increasing Emphasis On Investigations Concerning The Ultrastructure, Reproductive Biology, Ecology, Morphogenesis, Physiology, Biochemistry And Related Aspects Of Bryophytes. These Themes Have Also Rightfully Found Their Place In The Syllabi At All Levels In Most Universities All Over The Globe. However, The Writing Of Texts In This Area Has Lagged Behind. Since The Literature Is Scattered And At Times Not Easy To Reach, There Is An Urgent Need For A Book Which Deals With The Modern Topics Of Bryology. This Volume Is Intended To Fill This Gap. The Authors Have Tried To Make The Compilation Of The Literature As Up-To-Date As Possible, And The References Cited In The Text Have Been Listed At The End Of Each Chapter For Those Interested In More Details. Most Of The Illustrations Have Been Taken From Recent Research Publications And These Have Not Previously Been Included In Any Book As Far As We Aware. Summary Charts And Tables Are Provided At All Appropriate Places.
An informative, innovative and comprehensive text on the subject, the second revised edition of the book offers a coherent account of various aspects of pteridophyta, in the light of new findings. It covers the entire course of reading on the subject for BSc and MSc degrees.
This endeavour is aimed to be comprehensive and innovative. It covers the entire course of reading in Bryology. After a brief Introduction, there is an account of array of diversity and development of Bryophytes. In three chapters on Liverworts, Hornworts and Mosses, one can find an illustrated and concise account of all representative types. It is followed by comparative morphology. In two chapters on Gametophyte and Sporophyte are unravelled the elements of unity in diversity. Due emphasis has been given to experimental studies. In five chapters are traced the events of life cycle; Spore germination, Protonema differentiation and Gametophyte initiation, Sexuality and Sporophyte development, Regeneration, and Alternation of generations. Experimental studies – a backbone of this book – are not only interesting in a class room but informative to decipher different aspects of differentiation. Finally, there is food for thought in chapters on Cytogenetics and Evolution, and Origin and Fossil History. At the end is an extensive bibliography of old and new Literature, for further reading.
The book covers the entire course on archegoniate plants which is prescribed in the syllabi of different universities for undergraduate students. The presentation is comprehensive and innovative. The book describes different divisions of plant kingdom related to archegoniate plants covering their life cycle, relationship, classification and economic importance. Details of different genera in terms of morphology, anatomy, reproduction and sexuality have been explained with due diagrams. The book also discusses topics like heterospory, seed habit, leaf phylogeny, stellar system, alternation of generations, regeneration in general and special role of germ cells—egg and spore—in life cycle. Experimental studies described in the book highlight the phenomena of apogamy and apospory, their occurrence, induction and alternate role in life cycle. Also given are accounts on micropropagation of gymnosperms and ferns, for commerce and industry. Key Features • Covers Bryophytes, Pteridophytes and Gymnosperms • Loaded with up-to-date information gathered through research results • Supports description through explicit diagrams for clear understanding • Short and to-the-point description so as to cover the entire syllabus within a semester
For Degree, Honours and Postgraduate Students
This book is contain Pteridophyta,Gymnosperms and Palaeobotany compilation work and embodies a fairly comprehensive treatment of the fundamental facts and aspects of the subject. This book will serve as an introduction to Botany to the beginners in this field.

For the last 40 years this book has served well the students of Botany, Agriculture and Forestry for their regular courses like BSc. (General and Hons) and MSc., as well as competitive examinations. It has stood the test of time due to the authors’ zeal to update it regularly with inputs from latest developments in the field. Since the last revision of the book, the methods used to study plant embryology have changed radically. Powerful modern biological techniques are now being applied to understand the developmental aspects and genetic and molecular bases of embryological processes. It has become possible to generate tissue specific mutants by T-DNA insertional mutagenesis, use of green fluorescent protein probes for live imaging of growing cells and tissues and to analyze gene expression in few-celled structures, such as early stages of embryo, and constituent cells of the male and female gametophytes. These techniques, combined with the development of high resolution confocal laser scanning microscopy, have provided non-invasive methods to view live processes, such as pollen tube growth in the pistil and double fertilization under in situ conditions. The book has been translated into Japanese and Korean languages. KEY FEATURES • Well established text with content rigorous enough for both UG and PG studies • Covers important topics like development and structure of male and female gametophytes, pollination, fertilization, sexual incompatibility, development of endosperm and embryo, polyembryony, apomixis and seed development • Describes embryology in relation to taxonomy and experimental and applied embryology Use of tables and figures to depict important data and information • Updated as per the new developments in the study of plant embryology
Seedlings are highly sensitive to their environment. After seeds, they typically suffer the highest mortality of any life history stage. This book provides a comprehensive exploration of the seedling stage of the plant life cycle. It considers the importance of seedlings in plant communities; environmental factors with special impact on seedlings; the morphological and physiological diversity of seedlings including mycorrhizae; the relationship of the seedling with other life stages; seedling evolution; and seedlings in human altered ecosystems, including deserts, tropical rainforests, and habitat restoration projects. The diversity of seedlings is portrayed by including specialised groups like orchids, bromeliads, and parasitic and carnivorous plants. Discussions of physiology, morphology, evolution and ecology are brought together to focus on how and why seedlings are successful. This important text sets the stage for future research and is valuable to graduate students and researchers in plant ecology, botany, agriculture and conservation.
