The breadth and depth of knowledge concerning ethylene synthesis and action, coupled with the rapid pace of new progress makes a survey of the field a daunting task. Therefore, experts who were actively engaged in different aspects of ethylene research from different countries, spanning four continents were enlisted to complete this monograph. This book discusses a historical perspective as well as future trends and possibilities in this field.

International Series of Monographs on Pure and Applied Biology, Volume 8: Short Guide to Geo-Botanical Surveying focuses on the guide used in the geo-botanical surveying of pastures, bogs, and forests. The book first offers information on geo-botanical maps and plans and geo-botanical surveys. Discussions focus on the general features of geo-botanical maps and plans, classification of geo-botanical maps, transect surveys, auxiliary methods of investigation in geo-botanical surveys, and aero geo- botanical surveys. The text then examines geo-botanical surveys for forestry needs, including survey work in forest valuation, forest-typology surveys, and notes on interpretation of aerial photographs of forest vegetation. The publication ponders on geo-botanical surveys for the needs of the peat industry and agricultural reclamation of bogs and geo-botanical surveys for study of pastures. Topics include geo-botanical survey of bogs in connection with their agricultural reclamation; general information on geo-botanical surveys in bogs; features of surveys in semi-deserts and deserts; and features of surveys on the tundra. The text is a valuable source of data for readers interested in geo-botanical surveying.

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.
