International Review of Cytology
In recent years there has been a growing awareness of the importance of reproductive biology to crop production and there has been a tremendous increase in research on reproductive structures of higher plants. Presented here is a wide information of different aspects of micro- and macrosporogenesis, pollen-stigma interaction and recognition, pollen tube growth, cytoskeleton, in vitro and in vivo gamete fusion, and incompatibility. The most advanced techniques employed in studies on reproductive biology of higher plants are described in detail.
This book provides the biographies, and a related summary, of geneticists and breeders of maize who have contributed to the major discoveries in the 20th century. Their relationships to one another, as well as the general developments in maize genetics and breeding growth, are included. Photographs of events and related personnel, all part of the biographic presentation, portray the maize community and its growth. Most of the geneticists and breeders have a common origin in their training, and their sucessors are among the current contributors to maize development.
In Recognition of the Forgotten Generation D. L. MULCAHyl Pollen was long believed to serve primarily a single function, that of delivering male gametes to the egge A secondary and generally overlooked value of pollen is that it serves to block the transmission of many defective alleles and gene combinations into the next generation. This latter function comes about simply because pollen tubes carrying defective haploid genotypes frequently fail to complete growth through the entire length of the style. However, the beneficial consequences of this pollen selection are diluted by the fact that the same deleterious genotypes are often transmitted through the egg at strictly mendelian frequenci...
A formal task of the Forest Genetic Resources Study Group/North American Forestry Commission/Food and Agriculture Organization of the United Nations and Working Party 2.04.09 / Division 2- Physiology and Genetics /International Union of Forest Research Organizations, this international directory lists more than 1,800 forest geneticists and tree breeders from 86 countries. Each listing includes the entrant's title, mailing address, phone and fax numbers, and email address, when available. Indices organize entrants by country, by alphabetical order, by taxa of interest, and by research subjects.
Accoglie i risultati degli studi condotti nell’ambito di tre progetti (Progetto VINUM, Progetto ArcheoVino, Progetto Senarum Vinea) ai quali hanno partecipato, per un confronto sul tema della viticultura e della produzione del vino, rappresentanti di varie discipline, quali la storia, l’archeologia, la botanica, la storia della tecnologia, la biologia molecolare. I vari interventi ricostruiscono una storia della coltivazione della vite e dell’enologia nel bacino del Mediterraneo e di tutte le attività ad esse connesse, non ultimo l’uso cultuale del vino, con indagini più articolate per le aree toscane e laziali e apportano elementi utili ad approfondire l’evoluzione storica del paesaggio e delle singole componenti dell’ambiente.
Brings together some of the agricultural economists in Europe to discuss pressing issues regarding the reform of the CAP, such as EU agricultural, trade and development policies, and the role of the WTO.
This book contains edited and revised papers from a conference on 'Science and Technology for Managing Plant Genetic Diversity in the 21st Century' held in Malaysia in June 2000, organised by the International Plant Genetic Resources Institute (IPGRI). It includes keynote papers and some 40 additional ones, covering ten themes.The major scientific challenges to developing a global vision for the next century are identified and key research objectives are also discussed.
