Effects of independent 10−4, 10−6 and 10−8 M N-isopropyldecanamide and 20 mg C L−1 humic acid (HA) treatments on root dry mass, radicular superficial area and length of maize seedlings as analyzed by Delta-T scan software. Total root length was calculated as the sum of the lengths of primary and lateral roots. Data are expressed as percentage of control and represent normalized means from six independent experiments performed with maize seedlings (10 plants per treatment in each case). Bars represent standard deviation values
