The methods of off-season longan production in Thailand are presented: (1) application of potassium chlorate (as soil drench, foliar spray, and trunk or stem injection) and sodium chlorate to regulate flowering, and (2) cultivation of non-seasonal flowering cultivars. The physiological responses of longan to potassium chlorate and orchard management practices are briefly discussed.
