Book Description
The Flowering Process covers the physiological processes involved in the conversion from the vegetative to the reproductive state in higher plants. This book is composed of ten chapters, and begins with a description of the biological framework of flowering. The succeeding chapters deal with the link between ecology and the flowering process and the low temperature promotion of flowering. These topics are followed by discussions on methods of experimentation with cocklebur and the preparation of plant for response to photo period. Other chapters describe the effect of light, pigment, and timing on flowering process. The final chapters consider the synthesis, movement, and action of the flowering hormone. This book will prove useful to graduate students with subjects related to the mechanisms of flowering.

Book Description
The Biology of Stentor summarizes all that has been learned about the biology of a certain group of ciliate protozoa: the stentors. Topics covered range from form and function in Stentor to behavior, fine structure, growth and division, and reorganization. Regeneration is also discussed, along with polarity, metabolism, genetics, and primordium development. This volume is comprised of 20 chapters and begins with a characterization of Stentor, with emphasis on its particular advantages in addressing general problems of biology. The reader is then introduced to form and function in Stentor, particularly S. coeruleus. The following chapters focus on the behavior (food selection, swimming, response to light, etc.) of stentors and the fine points of structure in terms of which this behavior is to be explained and which demonstrate the highly complex and precise achievements of morphogenesis. The remaining chapters explore growth and division in Stentor as well as the course of reorganization and regeneration; development of the oral primordium and how it is activated and inhibited; rate of regeneration in relation to the polar axis; fusion masses of whole stentors; and reconstitution in disarranged stentors. Various species of Stentor are also described, together with the techniques used to study them. The final chapter deals with hypotheses concerning the morphogenesis of ciliates. This book will be of interest to students and practitioners of biology and physiology.

Book Description
Pure and Applied Biology, Volume 3: Physical Properties of the Steroid Hormones illustrates the efficiency of methodology for the solution of problems of isolation, identification and quantitative determination of the physical properties of steroids. This volume is composed of five chapters, and begins with a survey of the factors that influence the partition coefficient of steroid hormone, along with the consideration of the types and preparation of solvent systems for determination. The next chapter describes the chromatographic mobilities of steroids using several chromatographic methods, such as paper chromatography. A chapter presents the ultraviolet absorption data on structural correlations of steroids. Another chapter highlights the conversion of a steroid into a fluorescent compound through the steroid-acid interaction mechanism. The final chapter deals with the selective absorption spectra of steroids in concentrated sulfuric acid without heating. This book is directed primarily toward steroid chemists and researchers.

Book Description
Animal Hormones: A Comparative Survey, Part I—Kinetic and Metabolic Hormones provides a comprehensive coverage of the properties of kinetic and metabolic hormones of both vertebrates and invertebrates; the title particularly covers the sources, actions, and secretion of the said hormones. The text first details the general concerns with the hormones, such as the history, chemical activators, mechanical activation, types, and identification. The next chapter covers the sources of kinetic and metabolic hormones. Chapters 3 and 4 tackle kinetic hormones, while Chapter 5 discusses metabolic hormones. The book will be of great interest to students, researchers, and practitioners of zoology and biochemistry.

Book Description
The Term Systematic Botany Encompasses The Domain Not Only Of The Higher Plants, But Also Of The Lower Plants. Since It Is Not Possible To Treat Adequately The Various Plant-Groups Under A Single Volume, This Edition Is Restricted To A Discussion Of The Angiosperms. It Has Been Designed As A Textbook For The Undergraduate Students (Pass & Honours) Of All The Indian Universities And It Will Be Helpful To Postgraduate Students In Botany As Well As To The Study Of Agriculture And Allied Subjects. The Author Has Abandoned Bentham-Hookers System And Presented A New Scheme Of Angiosperm-Classification. Although The Latter Scheme, Like Any Other Envisaged Before, Has Its Shortcomings, It Represents The Most Probable Natural Relationship Among Flowering Plants.Almost All The Taxa Prevalent In The Indian Flora Have Been Dealt With, Covering 44 Orders And 193 Families. Generally, Each Order Has Been Discussed In The Light Of Phylogeny And With Emphasis On Its General Features, Circum Inter-Relationship, Origin And Means Of Identification Of Various Families (By Bracketed Keys). Those Families Prominent In The Countrys Flora Have Been Described Under Six Or Seven Different Heads, Depending On The Available Information. Though The Inconspicuous Ones Have Not Been Categorised Likewise, One Can Even Find In Them The Array Of Items Under Each Family Being Suitably Treated. Moreover, The Nomenclature Of Plants Have Been Checked And Brought Up-To-Date As Far As Possible. Part One Is An Expose Of Taxonomic Principles, While PartsThree And Four, Deal With The Dicotyledonous And Monocotyledonous Plants Respectively. Under Part Two, There Are Certain Specialised Topics Which Have A Bearing On The Study Of The Systematic Botany Of Angiosperms. A List Of Important Books And Papers Is Inserted At The End Of Each Part. In Brief, The Author Has Made Anattempt To Give A Complete Picture Of Angiosperm Systematics.

Book Description
Mineral Salts Absorption in Plants details the contemporary knowledge regarding the mineral salt absorption mechanisms of plants. The title first covers the history of mineral salt absorption in plants, and then proceeds to tackling the experimental materials and methods. Next, the selection discusses the mechanisms of ion transport. Chapter 4 deals with the factors affecting salt absorption, while Chapter 5 talks about salt absorption and metabolisms. In the sixth chapter, the text covers the structural aspects of salt absorption in cells. The seventh chapter discusses the salts relations of vascular plants. The selection also talks about the soil as a source of mineral salts, along with salt tolerance. The book will be of great use to botanists and horticulturists. Students and researchers in the field of mineral nutrition will also benefit from the text.

Book Description
International Series of Monographs in Pure and Applied Biology, Volume 9: The Vegetation of Poland focuses on the plant geography of Poland, including climate, hydrography, geology, and ecology. The selection first offers information on the historical outline of the development of plant geography and the factors affecting the geographical distribution of plants in Poland. Discussions focus on the development of phytogeographical cartography, floristic and ecological plant geography, and the climate, boundaries, land-relief, hydrography, and geology of Poland. The text then ponders on the influence of man and his economic activities on the vegetation of Poland and the floristic statistics and the elements of the Polish flora. The publication examines the terrestrial and fresh-water plant communities and vegetation of the Polish Baltic. Topics include composition and structure of plant communities and methods of their study, associations of coastal and inland dunes, aquatic and swamp associations, and the most important representatives of the benthic flora of the Polish Baltic. The manuscript is a dependable source of data for botanists and those concerned with the plant resources of nature, including agriculturists, horticulturists, and soil scientists.
