Physiological Response Of Kentucky Bluegrass Under Salinity Stress, Lijun Wang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Salinity is a significant stress for plants world-wide. In agriculture, salts reduce germination, overall growth, yield, and sometimes death in crop plants. Salinity similarly affects turfgrass in our urban landscapes. Kentucky bluegrass (Poa pratensis L.) is the most widely used cool-season grass in the northern part of the United States, including the cool-arid West, but generally is a salt sensitive species. The overall objectives of this study were to study the physiological responses of Kentucky bluegrass to salt stress and to evaluate the genetic similarity among the cultivars used in the research.

Four Kentucky bluegrass entries, two salt-tolerant and …

Impacts Of Preemergence Herbicides On Hybrid Bermudagrass Morphology, Patrick Alan Jones

Masters Theses

Preemergence (PRE) herbicides were evaluated in multiple experiments to determine their impacts on hybrid bermudagrass morphology [(C. dactolyn (L.) Pers. x C. transvaalensis (Burtt Davy)]. First, indaziflam and prodiamine were applied to hybrid bermudagrass rooted to various depths in either sand or silt loam mini-rhizotrons. Results indicated that prodiamine (a mitiotic inhibitor) and indaziflam (a cellulose biosynthesis inhibitor) both significantly reduced root length density compared to a non-treated control; however, indaziflam treated plants exhibited foliar injury (i.e., reddening, necrosis) while those treated with prodiamine did not.

The researchers surmised that reductions in root length density with indaziflam may compromise …

Dna Fingerprinting And Anastomosis Grouping Reveal Similar Genetic Diversity In Rhizoctonia Species Infecting Turfgrasses In The Transition Zone Of Usa, B. S. Amaradasa, B. J. Horvath, D. K. Lakshman, S. E. Warnke

Department of Agronomy and Horticulture: Faculty Publications

Rhizoctonia blight is a common and serious disease of many turfgrass species. The most widespread causal agent, Thanatephorus cucumeris (anamorph: R. solani), consists of several genetically different subpopulations. In addition, Waitea circinata varieties zeae, oryzae and circinata (anamorph: Rhizoctonia spp.) also can cause the disease. Accurate identification of the causal pathogen is important for effective management of the disease. It is challenging to distinguish the specific causal pathogen based on disease symptoms or macroscopic and microscopic morphology. Traditional methods such as anastomosis reactions with tester isolates are time consuming and sometimes difficult to interpret. In the present study universally …
