Book Description
Two inheritance studies were conducted at College Station, Texas, to determine the nature and mode of inheritance of fermentablecarbohydrates in stems of Sorghum bicolor (L.) Moench. harvested stems were stripped and topped, and the juice extracted on a cane press mill. Carbohydrates yield was defined as the sum of the glucose, fructose, sucrose and starch concentration in the juice times the volume of juice extracted. In one study involving 16 F1 hybrids from 2 female and 8 male parents, general cambining ability (GCA) values were significant for carbohydrate yield, juice volume and each of the carbohydrate fractions. Specific combining ability (SCA) values were significant only for glucose, fructose and sucrose. The predominance of additive over non-additivegenetic variance was confirmed by a GCA/SCA ratio of 13.6 for carbohydrate yield. Correlation and regression analysis indicated that juice volume and sucrose were the most important components of carbohydrate yield. Glucose, fructose and starch contributed only slightly more to the statistical model for predicting carbohydrates yield. Although the average heterosis effect was small and negative, 7 of the hybrids yielded more stem carbohydrate than the better parent. In addition, an average positive heterosis was found for yield of fresh heads, suggesting that higher grain yields of hybrids would offset any loss of stem carbohydrate. Another study consisted of 5 parents and the 10 F1 hybrids of a one-way diallel cross. The aprents represented a range (...).

Book Description
Sorghum Biochemistry: An Industrial Perspective explores the many uses for sorghum in industry and biofuels. Not only does it offer a detailed understanding of the physical and biochemical qualities of the grain, it also takes an in-depth look at the role sorghum plays in such industries as brewing and ethanol production and the mechanics of post-harvest processing and value addition. Sorghum has long been an important staple in Africa and Asia, but its value goes far beyond its uses in human and animal consumption. Sorghum is also used in many industries, including waxes, packing material, wall board, ethanol, beverages, and brewing, and one variety called sweet sorghum has also been used as a bioenergy crop. Sorghum Biochemistry: An Industrial Perspective offers a closer look at how the grain is used in such a variety of ways, and how we can continue to optimize its potential. Provides detailed biochemical studies on grain sorghum to inform researchers grappling with similar issues Offers foundational information on the quality and composition of sorghum as a grain Covers a variety of uses for sorghum in many industries, including food and beverage, energy, and brewing Includes photos and illustrations to enhance the understanding of processes and sorghum biochemistry

Book Description
Bioenergy and biofuels are generated from a wide variety of feedstock. Fuels have been converted from a wide range of sources from vegetable oils to grains and sugarcane. Second generation biofuels are being developed around dedicated, non-food energy crops, such as switchgrass and Miscanthus, with an eye toward bioenergy sustainability. Bioenergy Feedstocks: Breeding and Genetics looks at advances in our understanding of the genetics and breeding practices across this diverse range of crops and provides readers with a valuable tool to improve cultivars and increase energy crop yields. Bioenergy Feedstocks: Breeding and Genetics opens with chapters focusing primarily on advances in the genetics and molecular biology of dedicated energy crops. These chapters provide in-depth coverage of new, high-potential feedstocks. The remaining chapters provide valuable overview of breeding efforts of current feedstocks with specific attention paid to the development of bioenergy traits. Coverage in these chapters includes crops such as sorghum, energy canes, corn, and other grasses and forages. The final chapters explore the role of transgenics in bioenergy feedstock production and the development of low-input strategies for producing bioenergy crops. A timely collection of work from a global team of bioenergy researchers and crop scientists, Bioenergy Feedstocks: Breeding and Genetics is an essential reference on cultivar improvement of biomass feedstock crops.

Book Description
Cellulosic Energy Cropping Systems presents a comprehensive overview of how cellulosic energy crops can be sustainably produced and converted to affordable energy through liquid fuels, heat and electricity. The book begins with an introduction to cellulosic feedstocks, discussing their potential as a large-scale sustainable energy source, and technologies for the production of liquid fuels, heat and electricity. Subsequent chapters examine miscanthus, switchgrass, sugarcane and energy cane, sorghums and crop residues, reviewing their phylogeny, cultural practices, and opportunities for genetic improvement. This is followed by a detailed focus on woody crops, including eucalyptus, pine, poplar and willow. Critical logistical issues associated with both herbaceous and woody feedstocks are reviewed, and alternate strategies for harvesting, transporting, and storing cellulosic materials are also examined. The final sectionof the booktackles the challenge of achieving long-term sustainability, addressing economic, environmental and social factors. Cellulosic Energy Cropping Systems is a valuable resource for academics, students and industry professionals working in the field of biomass cultivation and conversion, bioenergy, crop science and agriculture. Topics covered include: Identifying suitable cellulosic energy crops that are adapted to a wide range of climates and soils Best management practices for sustainably growing, harvesting, storing, transporting and pre-processing these crops The development of integrated cellulosic energy cropping systems for supplying commercial processing plants Challenges and opportunities for the long-term sustainability of cellulosic energy crops This book was conceived and initiated by David I. Bransby, Professor of Energy and Forage Crops in the Department of Crop, Soil and Environmental Sciences at Auburn University, USA.

Book Description
This book is a collection of chapters concerning the use of biomass for the sustainable production of energy and chemicals–an important goal that will help decrease the production of greenhouse gases to help mitigate global warming, provide energy security in the face of dwindling petroleum reserves, improve balance of payment problems and spur local economic development. Clearly there are ways to save energy that need to be encouraged more. These include more use of energy sources such as, among others, manure in anaerobic digesters, waste wood in forests as fuel or feedstock for cellulosic ethanol, and conservation reserve program (CRP) land crops that are presently unused in the US. The use of biofuels is not new; Rudolf Diesel used peanut oil as fuel in the ?rst engines he developed (Chap. 8), and ethanol was used in the early 1900s in the US as automobile fuel [Songstad et al. (2009) Historical perspective of biofuels: learning from the past to rediscover the future. In Vitro Cell Dev Biol Plant 45:189–192). Brazil now produces enough sugar cane ethanol to make up about 50% of its transportation fuel needs (Chap. 4). The next big thing will be cellulosic ethanol. At present, there is also the use of Miscanthus x giganteous as fuel for power plants in the UK (Chap. 2), bagasse (sugar cane waste) to power sugar cane mills (Chap. 4), and waste wood and sawdust to power sawmills (Chap. 7).

Book Description
The demand for plant-based industrial raw materials has increased as well as research into expanding the utility of plants for current and future uses. Plants are renewable, have limited or positive environmental impact and have the potential to yield a wide range of products in contrast to petroleum-based materials. Plants can be used in a variety of different industries and products including bioenergy, industrial oil and starch, fibre and dye, rubber and related compounds, insecticide and land rehabilitation. This title offers a comprehensive coverage of each of these uses. Chapters discuss the identification of plant species with desired traits, their cultivation to obtain the needed raw materials, methods utilized in producing different finished products, current and future research in crop production and processing and the present state and future prospects for the industry. Providing the first systematic review of industrial crops and their uses, this book will be an important resource for students and researchers of crop science and agricultural policy makers.
