Anthocyanins are a group of phenolic compounds widely found in nature, occurring in all tissues of higher plants. Currently, there are over 600 identified anthocyanins, and their activity is related to the protection of plants against insect attacks and to the animals attraction for pollination and seed dispersal. Red fruits such as blueberries and cranberries are among the main sources of anthocyanins and can supply large quantities of this compound in a single meal. Several studies have shown the beneficial effects of anthocyanins on health due to its high antioxidant action through neutralising free radicals by the donation of hydrogen atoms. These beneficial effects include, among others, the anti-carcinogenic and anti-inflammatory activities, the protective effect against degenerative and chronic diseases, the risk reduction of cardiovascular diseases, and vision improvement. In addition to discussing the health benefits of anthocyanins, it also discusses different food sources for anthocyanins and the chemical applications.

Different phases of fruit development and utilization have been treated in many textbooks, reviews, and a host of scientific and professional papers. This seems, however, to be the first attempt to bring together case histories of so many different fruits and to present a balanced account of the whole period from set to harvest. Postharvest physiology, which has been in the centre of the picture in many former books, is at the bored line of the subject matter of this book, and has not been fully covered, except in a few cases. For this reason, two separate chapters deal with physiological and pathological aspects of fruit life after harvest.

The Maize Handbook represents the collective efforts of the maize research community to enumerate the key steps of standard procedures and to disseminate these protocols for the common good. Although the material in this volume is drawn from experience with maize, many of the procedures, protocols, and descriptions are applicable to other higher plants, particularly to other grasses. The power and resolution of experiments with maize depend on the wide range of specialized genetic techniques and marked stocks; these materials are available today as the culmination of nearly 100 years of genetic research. A major goal of this volume is to introduce this genetical legacy and to highlight current stock construction programs that will soon benefit our work, e. g. high-density RFLP maps, deletion stocks, etc. Both stock construction and maintenance are relatively straightforward in maize as a result of the ease of crossing and the longevity of stored seeds. Crossing is facilitated by the separate staminate (tassel) and pistillate (ear) flowers, a feature almost unique to maize. On the other hand, many of the genetic methodologies utilized with maize, including the precision of record keeping, can be adapted to other plants. Facile communication and a spirit of co-operation have characterized the maize genetics community since its earliest days. Starting in the 1930s, institutions such as annual Maize Genetics Cooperation Newsletter, the Maize Genetics Stock Center, and the annual maize genetics meeting provide continuity to the field.
