Figure 4. Impact of pre-treatment with DMTU or DPI on SA-induced ARF in mung bean hypocotyl cuttings.

The primary roots were removed from seedlings of 5-day-old germinated mung beans, incubated in DMTU or DPI for 4 h, moved into 0.4 mM SA for 24 h, washed three times and cultivated in distilled water for another five days. The number of adventitious roots was quantified and is expressed as the mean from three independent experiments with 30 explants for each treatment. The different letters above the bars indicate significant differences among the treatments (P<0.05), according to the LSD test.
