The book covers a vast array of methods for the analysis of volatile compounds exuded by plants. Some of these volatiles are of great commercial importance, including the aromas of wines and teas, and volatiles in fruits. Other volatiles such as essential oils can be useful for chemotaxonomic purposes, and a chapter on an emerging method, that of chemometric analysis of such data, is included. Isoprene and ammonia rarely find a place in analytical methods presented for plant materials, but methods for these volatiles are described in this book. The volatiles given off by flowers are also...

Chemical defence by means of toxins poisonous to otherorganisms, be they animals or plants, is widespread amongstthe plant kingdom - including microorganisms as well. Thisbook embraces the analysis of a wide range of plant toxinsand this fills a gap in the plant pathology and ecologicalbiochemistry fields. The topics covered include toxicextracellular enzymes, host selective toxins, elicitors, phototoxins, aflatoxins, mycotoxins, and ecotoxic substancetests by pollen germination and growth. The analyticalprocedures, which are used to evaluate the toxins, arecovered in such a way that the...

This book deals with the analysis of plant wastes, for example, by-products from the industrial production of consumer goods (beer, paper, fruit juice), organic carbon dissolved in soils, streams, etc., or the decomposition of natural wastes such as leaf litter. A vast array of chemical and physical methods are included for each topic.

Molecular Methods of Plant Analysis Concept of the Series The powerful recombinant DNA technology and related developments have had an enormous impact on molecular biology. Any treatment of plant analy- sis must make use of these new methods. Developments have been so fast and the methods so powerful that the editors of Modern Methods of Plant Analy- sis have now decided to rename the series Molecular Methods of Plant Analy- sis. This will not change the general aims of the series, but best describes the thrust and content of the series as we go forward into the new millennium. This does not...

Modern Methods of Plant Analysis When the handbook Modern Methods of Plant Analysis, was first introduced in 1954, the considerations were: 1. the dependence of scientific progress in biology on the improvement of existing and the introduction of new methods; 2. the difficulty in finding many new analytical methods in specialized journals which are normally not accessible to experimental plant biologists; 3. the fact that in the methods sections of papers the description of methods is frequently so compact, or even sometimes so incomplete, that it is difficult to reproduce experiments. These...

Die papierchromatographische Technik gewinnt steigend an Bedeutung fiir die Untersuchung pflanzlicher Stoffe und Stoff wechselprozesse. Sie vermittelt mit geringem apparativem Aufwand Zugang zu biologischen Problemen. Diese Anleitung ist fiir die Hand des Studierenden gedacht. Nach Durcharbeiten der 12 "Obungen in der dargestellten Reihen folge solI der Experimentator in der Lage sein, die Methodik der Papierchromatographie auf Grund der gewonnenen Erfahrungen und mit Hilfe der speziellen Literatur sinnvoll zur Losung eines Problems einzusetzen. Es ist die Absicht, die Moglichkeiten und...

The book describes in detail the latest quality control techniques of fruits like grapes, agrumen, peaches, persimmons, apricots, and nuts like almonds and chestnuts. The classical stock of routine methods is extended to include most recent techniques, such as random amplified polymorphic DNA analysis (RAPD) for the genetic characterization of chestnut varieties.

Given the growing importance of essential oils and waxes, this volume deals with the analysis of a broad spectrum of these compounds from many plant origins. Commercial oils such as olive oil are analysed as are trees such as eucalyptus, mentha, cedar and juniper. In addition, analysis of spices, seasoning, seaweeds, perfumes, liquors and atmospheric monoterpene hydrocarbons are to be found in this book. The volatiles of flower and pollen may be of importance in attraction of bees and other insects to certain plants for pollination purposes; this topic is also discussed. Waxes, both in the...

The analysis of vegetables and vegetable products is now an important part of everyday life. From the dietary point of view we need to know both the positive and negative aspects of the vegetables we consume - whether they have a high fibre content, for example, or what pesticide residues are present. And from the producers' standpoint, we need to know the methods that are being used to develop new and better vegetables. Thus, genetic analysis becomes important. In this book, a chapter on genetic mapping of pea is included, together with approaches to squash and pumpkin breeding with high...
