 1. Please state project objectives and what work was done this quarter to address them: This is a continuation of project 18-028C. 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.Leaves were collected for nutrient analysis, tree size measurements and HLB disease/health ratings were conducted. Fibrous roots were collected to assess root growth. Rhizotron pictures were taken. Data analysis was continued. 2. Please state what work is anticipated for next quarter: Rhizotron measurements will continue and data analysis will continue. Post-hurricane fruit drop evaluations will be conducted.  3. Please state budget status (underspend or overspend, and why): Budget status is as expected.
