Seedlings were grown hydroponically for 2 d after germination and then treated with the indicated concentrations of NAA for 5 d. (a) The number of lateral roots (LR) exposed to the indicated concentrations of NAA. (b) Photograph of lateral root emergence. (c) Change of elongation of the primary root (PR). (d) Hypocotyl elongation. Values represent the mean of three independent experiments and vertical bars indicate standard deviations (=45 seedlings). Asterisks indicate that the mean values are significantly different between the NAA treatments and controls ( <p><b>Copyright information:</b></p><p>Taken from "Regulation of tomato lateral root development by carbon monoxide and involvement in auxin and nitric oxide"</p><p></p><p>Journal of Experimental Botany 2008;59(12):3443-3452.</p><p>Published online 24 Jul 2008</p><p>PMCID:PMC2529230.</p><p></p
