Botany and plant sciences

In the European Alps the importance of forests as protection against ava- lanches and soil erosion is becoming ever clearer with the continuing increase in population and development of tourism.

The 9th International Conference on Plant Growth Substances was held at the University of Lausanne, August 30-September 4, 1976.

As editor of the two-part Volume V on photosynthesis in RUHLAND'S Encyclopedia, the forerunner of this series published in 1960, I have been approached by the editors of the present volume to provide a short preface.

The problems associated with the movement of water and solutes throughout the plant body have intrigued students of plants since Malpighi's conclusions in 1675 and 1679 that nutrient sap flows upward and downward in stems through vessels in both wood and bark.

One of the points clearly stressed in the beginning of this book is that the essential feature of any dynamic system is change and that, where there is change, there may also be growth and evolution.

Plant pathology embraces all aspects of biological and scientific activity which are concerned with understanding the complex phenomena of diseases in plants.

Throughout the world natural forest ecosystems have been, and are being massively disrupted or destroyed.

The originality of this volume is to reveal to the reader the fascination of some unfamiliar sensory organs that are sometimes ignored and often misunderstood.

Pollen transmits the male genetic material in sexual reproduction of all higher plants.

When WILHELM RUHLAND developed his plan for an Encyclopedia of Plant Physiol- ogy more than three decades ago, biology could still be conveniently subdivided into classical areas.

The Advanced Series in Agricultural Sciences is designed to fill a long-felt need for advanced educational and technological books in the agricultural sciences.

As plant physiology increased steadily in the latter half of the 19th century, problems of absorption and transport of water and of mineral nutrients and problems of the passage of metabolites from one cell to another were investigated, especially in Germany.

In the first part (Part A) of this volume on transport, there was an emphasis on the processes occurring at the membranes bounding the cells.

If, following the solvent extraction of a hydrocarbon from a plant, it is not known whether it is one or the other, a method of distinguishing the two is described by HENDRICKS, WILDMAN and JONES (1946).

'frees contribute a major part of fuel, fodder and fruit, and are an im- of bioenergy.

Haploid plants have the gametophytic number of chromosomes.

During the last decade, forest decline has become increasingly apparent.

Reaction Centers of Photosynthetic Bacteria is an updated record on the most recent insight into the struc- ture/function relationship of reaction centers from photosynthetic bacteria.

The beauty of a knotty oak tree is different from that of a lovely flower.

The economic costs of frosts in agriculture and horticulture in many parts of the world can be very significant.

Comprising about one hundred plates this atlas documents anddescribes the processes concerning the sexual reproductionin higher plants.

The biota of the earth is being altered at an unprecedented rate.

Forty chapters deal with various aspects of tissue culture, in vitro manipulation, and other biotechnological approaches to the improvement of maize.

New developments in computer science, biology, mathematics and physics offer possibilities to obtain deeper understanding of growth and forms of organisms.

The pulse of life with the seasons is a classic theme of biology, equally cap- turing every man's curiosity about early and late milestones of every year's cycle and the critical physiologist's inquiry into life's subtle signals and responses.

The Galton-Watson branching process has its roots in the problem of extinction of family names which was given a precise formulation by F.

Algae belong to the lower plants.

Since the middle of the Sixties, new types of formulation for biologically active com- pounds have been developed, which have been introduced into the literature under the term Controlled Release Formulations (CRF).

Carbohydrate as the primary product of photosynthesis has a vital role in the maintenance of life on this planet.

123 phase and hence have no direct bearing on the retention time of solutes.

3 There are other trends in the attempt to meld evolution and development which immodesty permits me to add.

This volume presents systematic treatments for the families and genera of the Malpighiales, which more recently have been recognised as a new major group of the eudicots.
