Changes on root hairs pattern in maize seedlings characterized by an increased number, density and length. A Control, B maize seedlings treated for 48 h with humic acids isolated from vermicompost [4 mM C L−1]. The light micrographs were obtained by FLO. The circled area in the root treated with humic acids shows a typical mitosis site for lateral root emergence. (Source: personnel file of FLO and LPC)
