Dormancy in hawthorn yam (Dioscorea rotundata [Poir.]) tubers poses challenges during storage and field planting due to prolonged dormancy periods, leading to fungal attacks and reduced sowing density. This study aimed to explore the efficacy of plant growth regulators (PGRs) in inducing early sprouting in commercial hawthorn yam tubers to mitigate these issues. Tubers were divided into apical, middle, and basal sections, treated with various PGRs, and sown in sterile substrate. Thiourea at 1.0 g L-1 emerged as the most effective treatment, promoting the highest percentage of sprouting across all observation periods. Thiourea at 2 g L-1.0 proved efficient for apical and middle sections, while mepiquat chloride at 2.0 mL L-1 stimulated sprouting in the basal part. These findings demonstrate the potential of PGRs in inducing early sprouting and enhancing germination uniformity in hawthorn yam tubers, offering practical implications for improved crop management.
