Download or read book Performance of Australian Provenances of Eucalyptus Grandis and Eucalyptus Saligna in Hawaii written by Roger G. Skolmen and published by . This book was released on 1986 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Australian provenances of Eucalyptus grandis and E. saligna were compared at four locations on the island of Hawaii to seek seed sources better than those in current use which were introduced earlier from unrecorded locations in Australia. A broad range of latitude and elevation was represented among the provenances. At all four locations, most E. grandis provenances outgrew most E. saligna. Considerable consistency was demonstrated among the good and poor provenances at each site. Although most differences between provenances were not statistically significant at the 5 percent level, the consistently good performance of several E. grandis provenances led to the recommendation that these seed sources be collected in Australia for future planting on similar sites on the island.

Available in PDF, EPUB and Kindle. Book excerpt: In a 1964-1967 study on the Challenge Experimental Forest, seedfall was evaluated in 2-, 5-, and 10-acre circular clearcuttings. During the 4 years, 10 seed crops, ranging from light to bumper, were produced by ponderosa pine. white fir, Douglas-fir, and incense cedar. Seedfall ranged from 76 to 40,691 sound seed per acre (188 to 100,547/ha) for a single species in a given year. From 89 to 100 percent of each species' seed fell within an area 1 1/2 times the height of the average dominant tree. Overall, seed distribution was highly variable.

Download or read book Handbook of Bioenergy Crop Plants written by Chittaranjan Kole and published by CRC Press. This book was released on 2012-03-22 with total page 876 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the world’s population is projected to reach 10 billion or more by 2100, devastating fossil fuel shortages loom in the future unless more renewable alternatives to energy are developed. Bioenergy, in the form of cellulosic biomass, starch, sugar, and oils from crop plants, has emerged as one of the cheaper, cleaner, and environmentally sustainable alternatives to traditional forms of energy. Handbook of Bioenergy Crop Plants brings together the work of a panel of global experts who survey the possibilities and challenges involved in biofuel production in the twenty-first century. Section One explores the genetic improvement of bioenergy crops, ecological issues and biodiversity, feedstock logistics and enzymatic cell wall degradation to produce biofuels, and process technologies of liquid transportation fuels production. It also reviews international standards for fuel quality, unique issues of biofuel-powered engines, life-cycle environmental impacts of biofuels compared with fossil fuels, and social concerns. Section Two examines commercialized bioenergy crops, including cassava, Jatropha, forest trees, maize, oil palm, oilseed Brassicas, sorghum, soybean, sugarcane, and switchgrass. Section Three profiles emerging crops such as Brachypodium, diesel trees, minor oilseeds, lower plants, Paulownia, shrub willow, sugarbeet, sunflower, and sweet potato. It also discusses unconventional biomass resources such as vegetable oils, organic waste, and municipal sludge. Highlighting the special requirements, major achievements, and unresolved concerns in bioenergy production from crop plants, the book is destined to lead to future discoveries related to the use of plants for bioenergy production. It will assist in developing innovative ways of ameliorating energy problems on the horizon.
