Evaluation Of Competition Between Turfgrass And Trees In The Landscape, Christopher A. Hendrickson
Evaluation Of Competition Between Turfgrass And Trees In The Landscape, Christopher A. Hendrickson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Population growth in regions of the Intermountain West has resulted in rapid growth of residential neighborhoods. In Utah, the landscapes associated with these expanding neighborhoods consume vast quantities of treated water. This is a concern in all states of the Intermountain West, as water becomes increasingly scarce. Traditionally used turfgrasses, trees and other plants in Intermountain West landscapes require significant amounts of supplemental water considering the intense sunlight, dry winds and sparse rainfall typical of the region. Characterizing the interactions between turfgrass and tree species in these landscapes can aid in the identification of candidate species that consume less nutritional …

Origins Of The Y Genome In Elymus, Pungu Okito
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The Triticeae tribe DUMORTER in the grass family (Poaceae) includes the most important cereal crops such as wheat, barley, and rye. They are also economically important forage grasses. Elymus is the largest and most complex genus with approximately 150 species occurring worldwide. Asia is an important centre for the origin and diversity of perennial species in the Triticeae tribe, and more than half of the Elymus are known to occur in the Asia. Cytologically, Elymus species have a genomic formula of StH, StP, StY, StStY, StHY, StPY, and StWY. About 40% of Elymus …
Simulated Browsing Impacts On Aspen Suckers' Density, Growth, And Nutritional Responses, Koketso Tshireletso
Simulated Browsing Impacts On Aspen Suckers' Density, Growth, And Nutritional Responses, Koketso Tshireletso
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Heavy and repeated ungulate browsing on reproductive suckers has limited trembling aspen (Populus tremuloides Michx.) regeneration on many Western landscapes. However, little is known about the specific effects of season and intensity of browsing. My objectives were to determine the effects of season and intensity of clipping (simulated browsing) on suckers’ (1) density and growth characteristics, and (2) nutritional quality and quantity.
Three randomly selected stands were clear-felled in mid-July, 2005, and fenced. Simulated browsing treatments of 0%, 20%, 40%, and 60% removal of current year’s growth were randomly applied in early, mid-, and late summers of 2006 and …
