Localization Of Expansin Expression During Adventitious And Lateral Rooting In Response To Auxin In Loblolly Pine, Fuyu Xu Jan 2002

Localization Of Expansin Expression During Adventitious And Lateral Rooting In Response To Auxin In Loblolly Pine, Fuyu Xu

Electronic Theses and Dissertations

Loblolly Pine is the most important and widely cultivated timber species in the southern United States. Due to its fast growth, it is extensively planted for lumber and pulpwood. Vegetative propagation will enhance gains from genetic improvement of tree species. Rooted-cutting is at present the most reliable non-somatic embryogenesis method for cloning specific genotypes. However, an abrupt decline of adventitious rooting capacity has hindered the application of vegetative propagation in loblolly pine. Unraveling the rooting mechanism may facilitate a way to overcome this barrier. Regulation of lateral and adventitious root formation by auxin has been demonstrated through the application of …


Wood Anatomy Of Metasequoia - Separation From Glyptostrobus And Function/Structure Considerations, George E. Visscher Jan 2002

Wood Anatomy Of Metasequoia - Separation From Glyptostrobus And Function/Structure Considerations, George E. Visscher

Electronic Theses and Dissertations

This thesis is part of a broader cooperative study aimed at understanding Paleo-forest dynamics -- namely those of the Eocene period in the Canadian High Arctic. Wood of the dominant tree species -- Metasequoia -- that grew on Axel Heiberg Island, Nunavut, Canada is the focus of this research. The text is divided into two chapters written as articles to be submitted to the International Association of Wood Anatomists Journal (IAWA). The first chapter of this text is a direct result of classifying the fossil wood of Axel Heiberg. The wood of Glyptostrobus is similar to that of Metasequoia. Because …


National And Regional Assessments Of Crop Yield Trends And Relative Production Efficiency : Theme 5.1. Land Use Change, Productivity And Diversification, David Stephens Jan 2002

National And Regional Assessments Of Crop Yield Trends And Relative Production Efficiency : Theme 5.1. Land Use Change, Productivity And Diversification, David Stephens

Agriculture reports

National and regional assessment in Australia of relative production (yield) efficiency for wheat and other cereals providing estimates of biological production potential based on seasonal climatic conditions, compared with actual production values for selected historical dates between 1982 and 2000.


Soil Health As An Indicator Of Sustainable Management, John W. Doran, Stamatis Stamatiadis, John Haberern Jan 2002

Soil Health As An Indicator Of Sustainable Management, John W. Doran, Stamatis Stamatiadis, John Haberern

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Population growth, a widening gap between the rich and poor, environmental degradation, and a re-evaluation of energy use and alternatives will shape life in the 21st century. We will be challenged to increase food supplies for a global population one-and-a-half to two times its current size. But as agricultural systems grow to meet the demands of more people, increased pressure will be placed on our natural resources: competition for land, water and energy resources from both urban and industrial sectors becomes more acute and the available land base remains static or shrinks. Under current practices increased food production will greatly …


Critical Period For Weed Control: The Concept And Data Analysis, Stevan Z. Knezevic, Sean P. Evans, Erin E. Blankenship, Rene C. Van Acker, John L. Lindquist Jan 2002

Critical Period For Weed Control: The Concept And Data Analysis, Stevan Z. Knezevic, Sean P. Evans, Erin E. Blankenship, Rene C. Van Acker, John L. Lindquist

Department of Agronomy and Horticulture: Faculty Publications

The critical period for weed control (CPWC) is a period in the crop growth cycle during which weeds must be controlled to prevent yield losses. Knowing the CPWC is useful in making decisions on the need for and timing of weed control and in achieving efficient herbicide use from both biological and economic perspectives. An increase in the use of herbicide-tolerant crops, especially soybean resistant to glyphosate, has stimulated interest in the concept of CPWC. Recently, several studies examined this concept in glyphosate-resistant corn and soybean across the midwestern United States. However, these studies presented various methods for data analysis …


Environmental Effects On Developing Wheat As Sensed By Near-Infrared Reflectance Of Mature Grains, Stephen R. Delwiche, Robert A. Graybosch, Lenis Alton Nelson, William R. Hruschka Jan 2002

Environmental Effects On Developing Wheat As Sensed By Near-Infrared Reflectance Of Mature Grains, Stephen R. Delwiche, Robert A. Graybosch, Lenis Alton Nelson, William R. Hruschka

Department of Agronomy and Horticulture: Faculty Publications

For 30 years, near-infrared (NIR) spectroscopy has routinely been applied to the cereal grains for the purpose of rapidly measuring concentrations of constituents such as protein and moisture. The research described herein examined the ability of NIR reflectance spectroscopy on harvested wheat to determine weather-related, quality-determining properties that occurred during plant development. Twenty commercial cultivars or advanced breeding lines of hard red winter and hard white wheat (Triticum aestivum L.) were grown in 10 geographical locations under prevailing natural conditions of the U.S. Great Plains. Diffuse reflectance spectra (1,100-2,498 nm) of ground wheat from these samples were modeled by …


Registration Of ‘Wahoo’ Wheat, P. Stephen Baenziger, B. Moreno-Sevilla, Robert A. Graybosch, J. M. Krall, M. J. Shipman, Roger Wesley Elmore, R. N. Klein, D. D. Baltensperger, Lenis Alton Nelson, D. V. Mcvey, John E. Watkins, J.H. Hatchett Jan 2002

‘Wahoo’ (Reg. no. CV-920, PI 619098) is a hard red winter wheat (Triticum aestivum L.) cultivar developed cooperatively by the Nebraska Agricultural Experiment Station and the USDA-ARS and released in 2000 by the developing institutions and the Wyoming Agricultural Experiment Station. Wahoo was released primarily for its superior adaptation to rainfed (syn. nonirrigated) wheat production regions in eastern Nebraska and broad adaptation to rainfed wheat production regions in Wyoming and Nebraska. Where it is adapted, Wahoo should be a good replacement cultivar for ‘Arapahoe’ (Baenziger et al., 1989). Wahoo is genetically complementary to ‘2137’, ‘Alliance’, ‘Buckskin’, ‘Jagger’, ‘Pronghorn’, and …
