Book Description
Seeds are a vital part of life on earth. They are fundamental for plant reproduction, and many seeds play an important role in the diet of man and domestic and wild animals. Knowledge of the appearance of seeds - seed morphology - is of great importance to botany and seed identification in relation to: seed setting, quarantine work, forensic work, seed poisening, studies of seed dispersal, seed banks and archaeological studies.;This bibliography contains 3775 references and is divided in two parts: handbooks, and articles and monographs. In the latter the bibliographical reference is supplemented by information of importance to seed identificaiton: genera mentioned in articles, keys, descriptions, drawings, photograph, scanning electron micrographs, anatomy and chemical methods. The index of authors contains the names of an extensive number of authors, cited in the bibliography, and in the index of genera more than 3900 genera, described in one or more of the publications are cited.

Book Description
In introducing ourselves it should be told that in our native Latvian language our name is written LesiJ;l. s. In most English publications, as in this work, the writing has been simplified to Lesins, and often only the first initial has been used. Our interest in Medicago was first aroused during 1936-38, while em ployed as teachers in the agricultural and home economics school at Be brene, Upper Zemgale, Latvia. Some plants of alfalfa (M. varia, M. media), locally called 'lucema', were found growing wild along roadsides in that area, though no alfalfa fields had been seen in the vicinity within the me mory of local farmers. Some roadside plants were dug out and transplanted to the garden, but their seedset was poor. During the next few years we paid only slight attention to alfalfa, the reason being that Latvia is a country with Atlantic climatic features (annual precipitation 600-700 mm; mild win ters for its 56°-58° N. Lat. , with January isotherms between -3° and -7° C; moderately warm summers, with July isotherms between 16° and 18° C), which together with its soils, mostly of acidic, podzolic type, is not well suited for alfalfa production. It was not until 1945 in Sweden that work on alfalfa came to the foreground, when the senbor author was assigned investi gations on alfalfa seed setting by Dr. Erik Akerberg, then director of the Swedish Seed Association branch station at ffituna.

Book Description
Bioenergy and biofuels are generated from a wide variety offeedstock. Fuels have been converted from a wide range of sourcesfrom vegetable oils to grains and sugarcane. Second generationbiofuels are being developed around dedicated, non-food energycrops, such as switchgrass and Miscanthus, with an eye towardbioenergy sustainability. Bioenergy Feedstocks: Breedingand Genetics looks at advances in our understanding of thegenetics and breeding practices across this diverse range of cropsand provides readers with a valuable tool to improve cultivars andincrease energy crop yields. Bioenergy Feedstocks: Breeding and Genetics opens withchapters focusing primarily on advances in the genetics andmolecular biology of dedicated energy crops. These chapters providein-depth coverage of new, high-potential feedstocks. The remainingchapters provide valuable overview of breeding efforts of currentfeedstocks with specific attention paid to the development ofbioenergy traits. Coverage in these chapters includes crops such assorghum, energy canes, corn, and other grasses and forages. The final chapters explore the role of transgenics in bioenergyfeedstock production and the development of low-input strategiesfor producing bioenergy crops. A timely collection of work from aglobal team of bioenergy researchers and crop scientists,Bioenergy Feedstocks: Breeding and Genetics is an essentialreference on cultivar improvement of biomass feedstock crops.

Book Description
In 1971, Dr. Quentin Jones, now of the National Hawaii, where an international panel convened to Program Staff, SEA, USDA, suggested that the discuss and assemble information on underexploit Plant Taxonomy Laboratory devise a format for ed tropical legumes. Conversations at that meeting concise write-ups on 1,000 economic plants (Duke and subsequent correspondence with the partici and Terrell, 1974; Duke et al. , 1975). Dr. C. F. pants also yielded new information on some of the Reed was contracted to search the literature on tropical legumes. Finally in 1978, 100 copies of the writeups these economic plants, which included 146 species of legumes. From 1971 through 1974, Dr. Reed were delivered to the International Legume Con prepared rough drafts of write-ups on the 1,000 ference at Kew, July 24th-August 4, and all were species. It was my responsibility to establish the given to potential cooperators before my lecture on format and monitor the write-ups, to ensure that the manual (July 31st). New information presented they would answer many questions on legumes in lectures at that conference and personal com directed to the USDA by our taxpaying public. munications behind the scenes have also been used Since then, a computerized system alerts me to to update and embellish the write-ups so that they new publications on legumes. I have ordered for are more than a bibliographic echo. our files copies of the more promising documents.
