1. Please state project objectives and what work was done this quarter to address them: Objective 1: Assess rootstock propagation method and rootstock cultivar effects on growth, health, and productivity of grafted Valencia trees during the early production years (years 4-6 after planting) in two commercial citrus production environments. Objective 2: Assess rootstock propagation method effect on tree performance, root architectures and uprooting resistance of Valencia trees after 5 years of growth.In both commercial trials, fruit were harvested to determine yield and fruit quality was analyzed. Trials had few fruit, either due to the impacts of hurricane Ian and/or because of decline from HLB. Trees at SWFREC have continued to decline from HLB and did not bear any fruits.  2. Please state what work is anticipated for next quarter:  Tree health and growth will continue to be monitored.  3. Please state budget status (underspend or overspend, and why):  Budget status is as expected.
