Abstract
The effects of exogenous auxins on root growth were evaluated using soybean genotype ‘HN89’ as plan materials. The seedlings were treated by different concentrations of indoleacetic acid (IAA), indolebutyric acid (IBA) and naphthylacetic acid (NAA). The results showed that only low concentrations (0.05 and 0.5 μmol·L-1 ) of IAA could promote both primary root elongation and lateral root development in soybean, IBA, NAA and high concentration of IAA inhibited the elongation of both primary and lateral roots, resulted in abnormal root development, and subsequently reduced soybean biomass. These results elucidated that different exogenous auxin regulated the soybean root architecture inordinately.
