FIGURE 2.

Effect of different concentrations of SNP on adventitious root development in cucumber explants under osmotic stress. The primary roots were removed from hypocotyl of 6-day-old seedlings. Explants were incubated for 6 days with distilled water (control) or 0.05% (w/v) PEG 6000 plus different concentrations of SNP. The numbers of adventitious root (A) and root length (B) were expressed as mean ± SE (n = 3, 10 explants were used per replicate). Bars with different lower case letters were significantly different by Duncan’s multiple range test (p < 0.05).
