The aim of this study was to evaluate the sensitivity of yellow mustard (Brassica juncea L) to plant regulators compound growth by the root length, root surface area, root volume, stem length and surface area. The experiment consists of three varieties of yellow mustard (RETRO, FELICIA and PRIMA) and eight growth regulators (Albit, Vermistimd, Antistress, Agrios, Regoplan, Biofoge, Stimulate, Fast start). The results showed that the growth compound regulator was the main factor causing the difference in root length and had no correlation with the variety. Different types of plant growth compound regulators have significant differences in the growth and development of mustard. For RETRO, the growth compound regulator VERMISTIMD significantly increased root growth compared with the control. In FELICIA, the length of root has changed under the influence of seeds inoculation with growth compound regulator BIOFOGE. However, the treatment of ANTISTRESS significantly inhibited the root length of FELICIA and RETRO. In the study of the PRIMA, all the growth regulators had no significant or inhibitory effect on the growth of the roots. In addition, there were also differences in the sensitivity of compound growth regulators to root and stem, for stem growth of FELICIA, the growth compound regulator VERMISTIMD has the opposite effect on the stem surface area and BIOFOGE has a significant impact on stem surface area of PRIMA.
