Comfrey In The Garden, Emmalee Rolfe, Dan Drost

All Archived Publications

Comfrey (Symphytum officinale) is a very hardy perennial herb adaptable to most conditions. Comfrey grows best in partial to full sun in moist, fertile soil. Comfrey is propagated by root cuttings or crown divisions. Comfrey can be planted throughout the growing season but establishes best when planted in the spring. Maintain moderate soil moisture, especially when plants are young. Once established, comfrey outcompetes weeds and does not have any reported insect or disease issues in Utah. Some leaves and roots are harvested after the first year of growth. It should be noted that consuming high doses or excessive …

Expression Of Malic Enzyme Reveals Subcellular Carbon Partitioning For Storage Reserve Production In Soybeans, Usda Agricultural Research Service, Donald Danforth Plant Science Center, Donald Danforth Plant Science Center, Thomas E. Clemente, Hanh T. Nguyen

Department of Agronomy and Horticulture: Faculty Publications

• Central metabolism produces amino and fatty acids for protein and lipids that establish seed value. Biosynthesis of storage reserves occurs in multiple organelles that exchange central intermediates including two essential metabolites, malate, and pyruvate that are linked by malic enzyme. Malic enzyme can be active in multiple subcellular compartments, partitioning carbon and reducing equivalents for anabolic and catabolic requirements. Prior studies based on isotopic labeling and steady-state metabolic flux analyses indicated malic enzyme provides carbon for fatty acid biosynthesis in plants, though genetic evidence confirming this role is lacking. We hypothesized that increasing malic enzyme flux would alter carbon partitioning …

Department of Agronomy and Horticulture: Faculty Publications

Drought stress is a major yield-limiting factor throughout the world in wheat (Triticum aestivum L.), causing losses of up to 80% of the total yield. The identification of factors affecting drought stress tolerance in the seedling stage is especially important to increase adaptation and accelerate the grain yield potential. In the current study, 41 spring wheat genotypes were tested for their tolerance to drought at the germination stage under two different polyethylene glycol concentrations (PEG) of 25% and 30%. For this purpose, twenty seedlings from each genotype were evaluated in triplicate with a randomized complete block design (RCBD) in …

Evaluation Of Pollination Traits Important For Hybrid Wheat Development In Great Plains Germplasm, Nicholas Garst, Vikas Belamkar, Amanda Easterly, Mary J. Guttieri, Hannah Stoll, Amir M. H. Ibrahim, P. Stephen Baenziger

Department of Agronomy and Horticulture: Faculty Publications

Hybrid wheat (Triticum aestivumL.) offers potential yield advantages over conventional inbred cultivars. For hybrid wheat to be a commercial success, the cost to produce the hybrid seed needs to be minimized. Although wheat is naturally selfpollinated, hybrid wheat seed production can be improved by increasing the amount and availability of pollen for cross-pollination. This research examined 19 pollination traits using the Hard Winter Wheat Association Mapping Panel for 3 years. Anther extrusion, pollen 50 date (date at which a genotype has 50% of spikes pollinating), plant height, and pollination duration (last spike pollen 50 date minus first spike …

Landscape And Site Factors Drive Invasive Phragmites Management And Native Plant Recovery Across Chesapeake Bay Wetlands, Christine B. Rohal, Eric L. G. Hazelton, Eliza K. Mcfarland, Rebekah Downard, Melissa K. Mccormick, Dennis F. Whigham, Karin M. Kettenring

Watershed Sciences Student Research

Successful invasive plant management—where invaders are sufficiently reduced and diverse native plant communities recover—remains an elusive goal for land managers. The site- and landscape-scale drivers of variable management outcomes and vegetation recovery are poorly understood due to a lack of rigorous experiments that characterize longer term vegetation trends across contexts. We present the results of a five-year experiment across eight subestuaries of Chesapeake Bay, representing a gradient of watersheds with differing dominant land-use types and anthropogenic impacts, to evaluate invasive and native plant response to herbicide management. The focal invader, Phragmites australis (common reed), is one of the most aggressive …

Linking Soil Properties to Originally Wooded and Afforested Areas

Matthew Laun, Ashton Crowe

Mentor: I. P. Handayani

Hutson School of Agriculture Murray State University, KY, USA

Abstract

Afforestation, adding an artificial forest to a piece of land that has been barren of trees for a significant amount of time, has some seriously huge impacts on the environment. These effects can be seen as an increase in the soil organic matter, a decrease in compaction, and enhancement of porosity. Therefore, the soil can support more diverse microbes and fungal communities leading to better micro and macro nutrient transfers between plants. This …

Department of Agronomy and Horticulture: Faculty Publications

Environmental stresses such as drought, high salinity, and low temperature can adversely modulate the field crop’s ability by altering the morphological, physiological, and biochemical processes of the plants. It is estimated that about 50% + of the productivity of several crops is limited due to various types of abiotic stresses either presence alone or in combination (s). However, there are two ways plants can survive against these abiotic stresses; a) through management practices and b) through adaptive mechanisms to tolerate plants. These adaptive mechanisms of tolerant plants are mostly linked to their signalling transduction pathway, triggering the action of plant …
