This project encompasses two different studies that together address production bottlenecks in the nursery and highlight the value of developing protocols to facilitate the development of underutilized crops. Desert olive (Forestiera pubescens), a large shrub or small tree native to the southwestern United States, exhibits ornamental value and potential for broader application in managed landscapes. Purported tolerances to both drought and flooding suggest F. pubescens is well-suited for diversification of landscapes in urban settings and in green infrastructure. However, if this species is to be adopted by the nursery trade and produced on a large scale, propagation protocols need to be developed. Mouse ear disorder (MED) is an issue commonly encountered in container production of river birch and pecan, but may be more widespread. New protocols involving nickel treatment would enable and enhance the production of persimmon and hazelnuts, as well as create guidelines that protect growers and the environment.enCorylusDesert oliveDiospyrosnickel deficiencyunderutilized native plantsunderutilized specialty cropThesis or Dissertation
