Driscoll’S Water-Use Efficiency (Wue) Strawberry Breeding Trial, Aidan Inoue
Driscoll’S Water-Use Efficiency (Wue) Strawberry Breeding Trial, Aidan Inoue
Plant Sciences
California’s water supply is seeing stress and growers are increasingly under pressure to lower their water use. While reducing irrigation to strawberry plants can be used to raise sugars (°bx), research on the impact of deficit irrigation on plant growth, fruit yield and quality are not yet quantified. The purpose of this experiment is to observe the effects of a ~50% deficit irrigation treatment on tabletop strawberry plants where drainage measurements and plant absorption can be recorded. Results indicate that plant vigor and total marketable yield are predominantly treatment dependent whereas fruit characteristics, including culls and berry size are reliant …

Water Conservation Through Drought-Resilient Landscape Plants And Deficit Irrigation, Ji-Jhong Chen
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Increases in urban population and inadequate rainfall result in imbalanced water budgets in urban and sub-urban regions. Water conservation becomes important in urban landscapes because of increased water demands. Modern landscape designs require drought-resistant plants to maintain urban landscape greenness during water scarcity. Irrigating plants at their irrigation requirements, which is the minimum irrigation rate that can achieve acceptable aesthetic quality, can also conserve water. However, the drought tolerance and irrigation requrements of most landscape plants have not been widely evaluated. Shepherdia ×utahensis ‘Torrey’ (‘Torrey’ buffaloberry) and Penstemon species (beardtongues) are low-water-use landscape plants, but their drought resistance mechanisms are …
