H2S-induced tomato lateral rooting is sensitive to the scavenger and synthetic inhibitor of H2O2. Three-day-old tomato seedlings were treated with H2O (Con), 1 mM NaHS, 100 μΜ H2O2, 500 μΜ N,N′-dimethylthiourea (DMTU), and 0.1 μΜ diphenylene idonium (DPI), alone or their combinations for 4 d. Corresponding photographs were taken (a). Bar = 1 cm. Meanwhile, the emerged LR density (b), LR length (c), the number of emerged LRs (>1 mm) per seedling (d), and primary root (PR) length (e) were analyzed. Mean and SE values were calculated from at least three independent experiments. Bars denoted by the same letter did not differ significantly at P < 0.05 according to Duncan’s multiple range test
