Abstract The pattern of potassium accumulation in stem mustard F_1 hybrid(JL92-3A×JL155)was studied. The result indicated that the potassium accumulation in various organs met Logistic growth curve. Peak period of potassium accumulation in root was at 11.9-16.1 leaf age, in leaf was at 12.1-17.3 leaf age, in stem was at 14.4-17.9 leaf age. During the peak period of potassium accumulation, plant accumulated amount of potassium which accounted for over 65 % of whole growth stage.
