In a significant advancement for Caribbean agricultural science, Antigua and Barbuda has established its first specialized plant tissue culture facility through bilateral cooperation with China. The pioneering laboratory, equipped with state-of-the-art technology including laminar flow hoods, high-pressure sterilizers, and constant-temperature incubators, represents a cornerstone of the China-Aided Agricultural Technology Project.
On January 21, 2026, the China–Antigua and Barbuda Modern Agricultural International Science and Technology Cooperation Base in Bethesda hosted an intensive technical workshop led by Dr. Lu Jiaju, an associate researcher from China’s Guizhou Institute of Subtropical Crops. The session brought together agricultural specialists from Antigua’s Ministry of Agriculture, Lands, Fisheries and the Blue Economy, specifically the Crop Research and Development Division.
Dr. Lu conducted comprehensive training covering all aspects of plant tissue cultivation, beginning with laboratory safety protocols and proper attire requirements. Participants received detailed instruction on functional laboratory zoning, equipment operation, and critical procedural stages including reagent preparation, medium formulation, sterilization techniques, and explant disinfection. Using sweet potato cuttings as demonstration material, Dr. Lu performed live demonstrations of sterilization processes involving alcohol immersion and sodium hypochlorite treatment, emphasizing precise timing controls.
The workshop employed a blended learning approach combining theoretical knowledge with hands-on practice. Trainees participated in group exercises within laminar flow cabinets, practicing cutting and inoculation techniques under expert supervision. Special emphasis was placed on maintaining aseptic conditions throughout all procedures, with detailed guidance on laboratory cleaning protocols and disinfection standards.
Concurrent training sessions focused on laboratory management and equipment maintenance for the core technical team who will operate the facility once it becomes fully operational. This comprehensive knowledge transfer enables Antigua and Barbuda to develop independent capacity for producing high-quality, disease-free seedlings, addressing long-standing agricultural challenges in the region.
The establishment of this facility, entirely funded and equipped through Chinese governmental support, marks a transformative step in Antigua and Barbuda’s agricultural development journey, potentially serving as a model for other Caribbean nations facing similar agricultural constraints.
