Effects Of Water Stress Preconditioning On Plant Water Relations And Transplant Survival Of Artemisia Cana And Agropyron Intermedium, Jerriann Ernstsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Typically, dormant seedlings are transplanted when revegetating nonirrigated disturbed lands in order to prevent transplant shock triggered by water stress. Since dormant seedlings have to be used, this limits the duration of the transplant season. It may be possible to increase this limited season by inducing acclimation responses that would increase drought tolerance. Preconditioning actively growing seedlings to water stress prior to transplanting could induce acclimation responses such as solute accumulation and/or stomatal modulation.

Under greenhouse conditions, A. cana and A. intermedium seedlings were subjected to three water stress preconditioning treatments: a well watered control, one dry-down cycle, and three …
