Key Responsibilities: * Grafting Operations: * Perform various grafting techniques (e.g., budding, cleft grafting, whip-and-tongue) on citrus trees and seedlings. * Carefully select and prepare scion wood (budwood) and rootstock for grafting, ensuring proper alignment of cambium layers for successful union. * Inoculate receptor trees with specific budwood to test for viral diseases, such as Citrus Tristeza Virus (CTV). * Propagate desirable citrus scions onto appropriate rootstock to create new trees with improved characteristics (e.g., disease resistance, dwarfing, fruit quality). * Monitor grafted plants regularly (e.g., every two weeks) to check for successful establishment of the graft union. * Plant Care and Maintenance: * Hand water and fertilize citrus trees and seedlings in the nursery or greenhouse. * Assist with transplanting citrus seedlings and other plants as needed. * Maintain a clean and organized greenhouse and work area, including washing pots and sanitizing equipment. * Scout for insect pests and report findings to supervisors. * Occasionally assist with spraying micronutrients or non-restricted use pesticides under supervision. * Quality Control and Record Keeping: * Maintain accurate plant identification throughout the grafting and testing process. * Label plants with block number, plant number, and date. * Compare incoming plants with paperwork to ensure correct identity. * Prepare and process plant samples for testing (e.g., cutting tissue, grinding samples, transferring extracts). * Maintain detailed records of grafting procedures, success rates, plant health, and any issues encountered. * Assist in identifying diseased greenhouse plants. * General Nursery/Laboratory Support: * Operate and maintain basic agricultural and laboratory equipment (e.g., soil sterilizer, pipettes, grinders). * Prepare soil mixes for potting plants. * Sanitize equipment and workstations before and after use. * Wash and dry equipment appropriately. * Prepare sample bags with labels for field collection. * Unload sample deliveries to the lab or refrigeration. * Perform other job-related duties as requested by the supervisor. Required Skills and Qualifications: * Technical Skills: * Proven experience and proficiency in various plant grafting techniques, specifically with citrus. * Basic knowledge of plant physiology, horticulture, and plant propagation. * Familiarity with plant diseases and pest identification. * Ability to follow detailed protocols and procedures precisely. * Experience with general greenhouse operations and plant care. * Physical Demands: * Ability to perform repetitive motions. * Capable of lifting and carrying items weighing up to 25-50 lbs (e.g., bags of soil, fertilizer). * Ability to stand for extended periods. * Manual dexterity and good eye-hand coordination.
