Effects of SNP and c-PTIO on tuber sprouting. (A) Effect of different SNP concentrations on tuber dormancy release. Dormant tubers were sprayed with DW (control) or 10, 20, 40, 80, 160, or 320 μM SNP for 15 min. (B) Effect of SNP and the NO scavenger c-PTIO on tuber dormancy and sprouting. Dormant tubers were sprayed with DW (control), 40 μM SNP, 1 mM c-PTIO, or 40 μM SNP + 1 mM c-PTIO for 15 min. Data are presented as the mean ± SD for three replicates. When p < 0.05, the difference is significant according to Duncan multiple-range test. Values marked with the same letter indicate no significant difference.
