Expression Analyses And Identification Of Key Molecular Participants In Plant Responses To Environmental Cues, Praveena Kanchupati
Expression Analyses And Identification Of Key Molecular Participants In Plant Responses To Environmental Cues, Praveena Kanchupati
Electronic Theses and Dissertations
Plants constantly engage and interact with the environment and respond to the changes in conditions like temperature, water, and photoperiod, by regulating expression of genes of multiple regulatory and signaling pathways. Insight into these pathways and their participants has provided and will provide candidates to improve various agronomically important traits in crops through marker-assisted breeding and genetic manipulation. With this aim in mind, in the present study, I attempted to identify key candidate genes that are involved in the regulation of; i) plant response to low temperature stress, ii) plant roots’ response to soil moisture content and iii) flowering time. …
Identification Of Physiological And Morphological Traits Governing High Water Use Efficiency In Alfalfa, Krishna Ghimire
Identification Of Physiological And Morphological Traits Governing High Water Use Efficiency In Alfalfa, Krishna Ghimire
Electronic Theses and Dissertations
Alfalfa is an important forage crop worldwide. Being deep-rooted, N2-fixing and high yielding, alfalfa has great economic, ecological and nutritional benefits. While alfalfa is a high yielding crop, its high productivity depends on irrigation water in many areas and consumes the greatest amount of water among all the major crops. With a growing demand for water resources due to an increase in human population and industrial water use, plus frequent drought due to climate change, irrigation water has become increasingly scarce and expensive. To sustain high production of alfalfa with limited water resource, alfalfa cultivars with improved water use efficiency …
Evaluation Of Gamebird Use And Thermal Characteristics Of Alfalfa And Perennial Grasses In Eastern South Dakota, Neal P. Martorelli
Evaluation Of Gamebird Use And Thermal Characteristics Of Alfalfa And Perennial Grasses In Eastern South Dakota, Neal P. Martorelli
Electronic Theses and Dissertations
The northern Great Plains provide critical breeding habitat for waterfowl and gamebirds in the United States. Peak commodity prices in the late 2000s resulted in increased agricultural production and large-scale conversions of grassland habitat to monoculture row crops. However, recent declines in commodity prices have created a renewed interest for private landowners to diversify crops and enroll in government subsidized conservation programs that convert idle grassland and unproductive cropland to wildlife friendly perennial grassland plantings. Exploring alternative grassland restoration techniques can improve the efficiency of management practices to benefit future wildlife habitat and productivity on both public and private lands. …

Identifying Promising New Falcata Alfalfa Populations For Use In Semiarid Rangelands, Derek Kannenberg
The Journal of Undergraduate Research
Alfalfa (Medicago sativa L.) is a valuable crop worldwide. In addition to its use as forage, the nitrogen fixation capabilities of root nodules make it a valuable component for improving soil health. Unfortunately, the semi-arid region of the Northern Great Plains introduces a number of environmental stresses that are detrimental to stand establishment and persistence. The ability to produce adventitious shoots from roots is generally considered a favorable trait for increasing stress resistance. This study aimed to identify alfalfa populations possessing the ability to produce adventitious shoot from root segments. Seven Plant Introductions (PIs), selected from the National Plant …

Alfalfa performs admirably an irrigated crop in South Dakota-so well that it is often neglected. When given attention, it can realistically maintain irrigated yields of 6 to 7 TIA each year in most of South Dakota where 1 to 2 T are produced on dryland. Irrigated land that will produce 100-130 bu corn will produce 5-7 T alfalfa. On poorer irrigated land that produces 50-70 hu corn, one can expect 3-5 T alfalfa. Alfalfa has higher water requirements for peak yields than most other crops. It may not reach its full potential yield in any part of the stale without …
