This book comprises the contributions of the international workshop Boron 2001 which was aimed at gathering all relevant information on recent developments in boron research in soils, plants, animals and men over the past years. Review articles and original contributions deal with both applied and basic aspects in this area, comprising topics such as methods for B determination, the physiological functions of boron in plant and animal metabolism, including use of 10B for diagnostic purposes and cancer treatment. Genetic and molecular aspects of boron efficiency and tolerance to toxic levels in plants and the early physiological reactions to boron deprivation are further important topics of this volume. The role of boron for reproductive development is dealt with in further contributions. Furthermore, improved methods for the diagnosis of the available boron status in soils, plants appropriate timing and leaf fertilizer application are addressed. Special emphasis is given in the contributions to highlight the most recent developments in the aforementioned areas.

This is a comprehensive review of knowledge of boron in soils, plants and animals, which coincides with a period of significant progress in boron research. It covers mid-1990s advances in the identification of the physical and chemical role of boron in the cell wall, the characterization of the genetic basis for differences in boron accumulation and tolerance to boron excesses and deficiencies, and the identification and characterization of the mechanizations of phloem boron transport. Each of these advances has contributed not only to an understanding of the fundamental behaviour of boron in plants, but also has a direct impact on boron management in agricultural systems. There are 13 review papers written by international scientists. The book should be of interest to scientists and advisers responsible for ensuring that plant growth is not limited by boron deficiency or toxicity, and it may be used as a reference book for students in agriculture, forestry, soil sciences and animal and human health.

The Boron '97 meeting was a great success in summarising all recent developments in basic and applied research on boron's function, especially in plants.

The economic significance of boron (B) in agriculture, horticulture, and forestry has been beyond dispute for several decades. Even in the last two decades, the areas where B deficiency limits plant production has grown with increased reports from China, south Asia and southeast Asia. The present volume is reflective of the growing awareness of the significance of low soil B with reports from Australia, Bangladesh, Brazil, north, central and southern China, India, Nepal, and the North West Frontier Province of Pakistan contained herein. Boron deficiency also continues to be a problem for crop yield and quality in areas where B deficiency has been known for some time, for example in Germany and the USA. The problem of low soil B is not limited to effects on field crop yield, with papers reporting on depressed wood yield and quality in timber trees (Lambert et al. ), and depressed fruit quality (Dong et al. ; Smith et al. : Zude et al. ) also appearing in the present volume. Globally, Shorrocks (1997)1 estimates that ?? tonnes of B fertiliser is applied annually in agriculture. The economic benefits from the use of B fertiliser have not been quantified but are clearly enormous. Paradoxically, the clear economic imperatives for using B fertiliser on low B soils are not matched by a similar clarity of understanding of the role and functions of B in plants.

This symposium on 'Boron in Soils and Plants' completes a quartet of reviews of the behaviour in soils and plants of four trace elements, copper, manganese, zinc and boron, selected for their importance in agriculture. The series had its genesis in a suggestion from Professor Robin Graham of the Waite Agricultural Research Institute that it would be appropriate in 1981 to celebrate the Golden Jubilee of the publication in 1931 of the first definitive evidence for the essentiality of copper in plants. The previous decade had seen a resurgence of interest in copper deficiency and toxicity in agriculture and an expansion of our understanding of the behaviour of copper in soils and plants. We therefore decided to promote a review of our understanding of the behaviour of copper in soils and plants by inviting appropriate authors to prepare reviews of 14 topics for publication in a book and presentation at a Golden Jubilee International Symposium on 'Copper in Soils and Plants'. Posters of current research were also displayed and published. Murdoch University, Perth, Western Australia was chosen as the venue because of its then current research on copper, the importance of copper in Western Australian agriculture, and the presence in Perth of many international nutritionists due to the fortuitous scheduling in 1981 of the 'Fourth International Symposium on Trace Element Metabolism in Man and Animals'.

This book is intended to bring together the contributions of many years of investigations from a number of laboratories involved in the systematic investigation of mother-offspring interactions and the attendant conse quences for development. A similar book (Rheingold, 1963) is now more than a decade old. The value of such a book is attested to by the burgeoning interest in the subject matter since the publication of that earlier volume. The importance of the mother-infant dyad has been recognized by scientests and parents alike since time immemorial. Pioneering writers such as Sigmund Freud, with his emphasis upon the expression of biological "needs" by the developing infant, and John B. Watson, with his emphasis upon the mother's role as a conditioner-trainer of her offspring, have been followed (in time, not emphases) by such investigators as Konrad Lorenz, with his now classic studies of imprinting, Jean Piaget's sequential analyses of the development of intellect, and Harry Harlow's ingenious studies of attach ment. The present volume reflects the influences of these earlier investigators. It is comparative, psychobiological, and represents a blend ofthe "experimental" approach characteristic of those trained in experimental psychology and the "natural history" approach more often represented in the work of ethologists. Sequential analyses of developmental changes in the mother-offspring relationship characterize virtually all of the work reported herein.
