Rooting Characteristics And Antioxidant Pigment Responses Of Three Hybrid Bermudagrass [Cynodon Dactylon (L.) Pers. × Cynodon Transvaalensis Burtt- Davy] Cultivars Exposed To Drought, Cory Alan Yurisic
Masters Theses
With recent changes in global climate, water use and its conservation have become important topics of discussion. Turfgrasses for lawns, parks, and other recreational areas are often perceived negatively due to the need for irrigation. The identification of turfgrasses possessing an improved ability to withstand water deficit is an important goal in science to curb irrigation requirements in the landscape. Newly released cultivars of hybrid bermudagrass (C. dactylon L. x. C. transvaalensis Burtt-Davy) have demonstrated improved tolerance to stresses such as cold, traffic, and water deficit; however, drought resistance mechanisms of these new cultivars have been largely uninvestigated. Drought …
Effects Of Fully Developed Vesicular Arbuscular Mycorrhizal Hyphae On Seed Germination Of Lolium Perenne, G Keith Bartley Jr, Richard J. Gualandi Jr, Robert M. Augé
Effects Of Fully Developed Vesicular Arbuscular Mycorrhizal Hyphae On Seed Germination Of Lolium Perenne, G Keith Bartley Jr, Richard J. Gualandi Jr, Robert M. Augé
Gregory Keith Bartley Jr.
Previous studies demonstrate that the inoculation of mycorrhizal spores in seeds can improve speed of germi- nation and establishment in grass seedlings. The universally positive effects of arbuscular mycorrhiza on plants suggest that fully developed mycorrhizal hyphae could potentially induce faster germination in seeds. This study presents data indicating that the inoculation of full grown hyphae in seeds of Lolium perenne inhibits speed of germination, independent of level of available soil nutrients. Daily measurements of seedling height between in- fected and non-infected plants at different starter fertilization rates in a sand profile showed that abuscular mycor- hiza influenced seeds emerged …
