Effects of hydrogen-rich water (HRW), sodium nitroprusside (SNP), and HRW plus NaN₃ or tungstate on the vase life of cut lily flowers. The cut flowers were placed randomly in distilled water (control), 150 μM SNP, 1% HRW, 1% HRW + 50 μM NaN₃ and 1% HRW + 100 μM tungstate to investigate. The values of vase life (A) are the mean ± SE of three independent experiments. Bars with different letters illustrate significant differences (p < 0.05) according to Duncan’s multiple range test. Photos (B) were taken after 8 days of treatments.
