The Relationship Between Salinity And Drought Tolerance In Turfgrasses And Woody Species, Nisa Leksungnoen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Both salt and water deficit make it difficult for plants to uptake water from soil. Thus, plants under those conditions may respond and deal with them similarly. The overall objectives of this study were to 1) determine visual appearance and physiological responses, and mechanisms to deal with salt and water deficit of turfgrasses and woody species, and 2) determine the relationship between salt and water deficit tolerance ability in those species.

Five turfgrass entries, ‘Gazelle’ and ‘Matador’ tall fescue (TF), ‘Midnight’ Kentucky bluegrass (KBG), PI368233 (Tolerant KBG), and PI372742 (Susceptible KBG), and three woody species, bigtooth maple (xeric-non saline), bigleaf …
