Isolation Of Bacterial And Fungal Microbes From The Rhizosphere Of Shepherdia Utahensis 'Torrey', Ty Wilson, Katie Hewitt Dec 2022

Isolation Of Bacterial And Fungal Microbes From The Rhizosphere Of Shepherdia Utahensis 'Torrey', Ty Wilson, Katie Hewitt

Fall Student Research Symposium 2022

My presentation is on the Isolation of Bacterial and Fungal Microbes from the Rhizosphere of Shepherdia x utahensis 'Torrey' also known as Hybrid Buffaloberry. Hybrid Buffaloberry is a combination between two varieties native to the Intermountain West: Shepherdia argentea, a highly drought tolerant variety, and Shepherdia rotundifolia, a common more aesthetically pleasing variety. Both native varieties are well documented to have nodule forming microbes that help aid their development in such harsh conditions. We acquired our Rhizosphere sample by shaking the roots and nodules from our sample in a phosphate buffer and serially diluted it to a useful concentration. We …


Understanding How Changes In Precipitation Intensity Will Affect Vegetation In The Western U.S., Cristina Chirvasa Dec 2021

Understanding How Changes In Precipitation Intensity Will Affect Vegetation In The Western U.S., Cristina Chirvasa

Fall Student Research Symposium 2021

Precipitation events are becoming more intense as the atmosphere warms, but it remains unclear how precipitation intensification will affect plant growth in arid and semiarid ecosystems. There is conflicting evidence suggesting that larger precipitation events may either increase or decrease plant growth. Here, we report the growth responses of herbaceous and woody plants to experimental manipulations of precipitation intensity in a cold, semi-arid ecosystem in Utah, USA. In this experiment, precipitation was collected and redeposited as fewer, larger events with total annual precipitation kept constant across treatments. Results from the first two growing seasons revealed that more intense events ‘pushed’ …


Identification And Isolation Of Halotolerant Endophytes In Ceanothus Velutinus May Lead To Plant Health In Saline Conditions, Katherine Hewitt Dec 2021

Identification And Isolation Of Halotolerant Endophytes In Ceanothus Velutinus May Lead To Plant Health In Saline Conditions, Katherine Hewitt

Fall Student Research Symposium 2021

Plant-microbe relations are integral to plant survival and crop productivity. Part of a plant’s biosphere are endophytes, microbes found between the cells of a plant. Endophytes can be beneficial to help a plant cope with abiotic stressors such as salinity. In Utah, our soils are high in salinity due to topography and climate. Climate change has increased soil salinity across the world, and water availability is becoming scarcer leading agriculture to use more saline sources to irrigate. Thus, salt is a concern for farmers. We aim to identify halotolerant endophytes from Ceanothus velutinus, Snowbrush which is native to the …


Plant-Soil Feedbacks Help Explain Biodiversity-Productivity Relationships, Leslie E. Forero, Andrew Kulmatiski, Josephine Grenzer, Jeanette M. Norton Jun 2021

Plant-Soil Feedbacks Help Explain Biodiversity-Productivity Relationships, Leslie E. Forero, Andrew Kulmatiski, Josephine Grenzer, Jeanette M. Norton

Wildland Resources Student Research

Species-rich plant communities can produce twice as much aboveground biomass as monocultures, but the mechanisms remain unresolved. We tested whether plant-soil feedbacks (PSFs) can help explain these biodiversity-productivity relationships. Using a 16-species, factorial field experiment we found that plants created soils that changed subsequent plant growth by 27% and that this effect increased over time. When incorporated into simulation models, these PSFs improved predictions of plant community growth and explained 14% of overyielding. Here we show quantitative, field-based evidence that diversity maintains productivity by suppressing plant disease. Though this effect alone was modest, it helps constrain the role of factors, …

Sabie Water Use, Andrew Kulmatiski

Plant root distributions are thought to determine plant growth and coexistence, but are notoriously difficult to measure. This dataset describes the concentration of deuterium oxide in plant tissues in plots where deuterium oxide was injected to target depths.


Usu Researchers Find That Lighting Efficiency For Plant Growth Has Doubled In Six Years, Usu Crop Physiology Lab Jan 2014

Usu Researchers Find That Lighting Efficiency For Plant Growth Has Doubled In Six Years, Usu Crop Physiology Lab

Controlled Environments

Nelson and Bugbee compared the efficiency of 22 lighting fixtures and found that the best light emitting diode fixtures—commonly known as LEDs—and the best high pressure sodium fixtures—often used in street lamps—are equally efficient. These two types of fixtures, however, provide optimum light for plants in significantly different ways.


Developing An Optimized Light Spectrum For Plant Growth And Development, Kevin Richard Cope May 2013

Developing An Optimized Light Spectrum For Plant Growth And Development, Kevin Richard Cope

Undergraduate Honors Capstone Projects

Light-emitting diodes (LEDs) are a rapidly developing technology for plant growth lighting and have become a powerful tool for understanding the spectral effects of light on plants. Several studies have shown that some blue light is necessary for normal growth and development, but the effects of blue light appear to be species dependent and may interact with other wavelengths of light as well as photosynthetic photon flux (PPF). Here we report the photobiological effects of three types of white LEDs (warm, neutral and cool) on the growth and development of radish, soybean, and wheat. All species were grown at two …
