Genetic Resources of Mediterranean Pasture and Forage Legumes is a comprehensive review of grassland improvement in Mediterranean areas using legume species. The book includes a detailed account of the processes involved in understanding the ecology of legumes and their collection in the Mediterranean, through to their preliminary evaluation and storage at various Genetic Resource Centres. A generic conspectus and key to the forage legumes of the Mediterranean basin is also included. These proceedings are truly international with examples on the collection and use of Mediterranean...

Plants are an important source of food and of valuable products for industry, agriculture and medicine. They are unique in many aspects of metabolic processes, development and reproduction. Most of these aspects can now be studied by the modern methods and technolo gies of molecular and cellular biology. Such studies are also encouraged as to improve plant yield and quality. During the past decade research in plant sciences has demonstrated the feasibility of plant cell and tissue culture techniques as major tools in biology and agriculture. These techniques are also essential in strategies...

In the series of International Protoplast Symposia the Symposium of 1987 was held in Wageningen (The Netherlands). Earlier Symposia took place in Jena (DDR) 1963, Brno (CSSR) 1967, Salamanca (Spain) 1971, Nottingham (UK) 1975, Szeged (Hungary) 1979 and Basel (Switzerland) 1983. This 7th International Protoplast Symposium was organized by K.J. Puite (Secretary), J.J.M. Dons (Treasurer), H.J.Huizing and E.J.L. Hotke-Staal (Local Organizers), the first three persons being scientists, respectively, from the Research Institute Ital, the Institute for horticultural plant breeding IVT and the...

Increased interest in the basic biology of plants and microorganisms stems from the fact that crop productivity is directly affected by plant-microbe interactions. In spite of the fact that plants exist in the environment amongst diverse species of microorganisms, only a few ever establish a direct relationship. Emerging awareness concerning the indirect effect of microbial association on plant growth and the possibility of using one microbe against another for controlling pathogenic interactions is at the genesis of new fields of studies. The primary reason for a microbe to associate with-...

This Symposium, held August 4-10, 1985 on the campus of Oregon State University in Corvallis, is the sixth of a series of international symposia concerned with broad aspects of the fixation of nitrogen gas by biological and chemical means. The first symposium of this series was held in Pullman, Washington (1974), the second in Salamanca, Spain (1976), the third in Madison, Wisconsin (1978), the fourth in Canberra, Australia (1980) and the fifth in Noordwij~erhout, The Netherlands (1983). Prior to the organization of these symposia, small groups of usually no more than 10 or 12 of the now "old...

In 1980, a conference on tissue culture of fruit crops was held at Beltsville to summarize the current status of this technology and to stimulate interest in it among research scientists, students, and commercial producers in the U. S. Interest in that conference and the proceedings from it far exceeded the expectations of the organizing committee. Since that time, micropropagation of fruit crops in the U. S. has increased significantly, but still lags far behind applications to production of ornamental plants. Within the past two years, a number of new laboratories have been established and...
