Abstract

In this research, the growth inhibition of Branica campestris induced by bromic was examined to estimate effect of counter cation that is potassium (K) and sodium (Na). Consequently, KBr didn't decrease length and dry weight of the edible part and just promoted growth increasingly. Growth inhibition of bromate was getting stronger with its concentration. At low concentration of 1 mg/L KBrO₃, Brassica campestris grew larger than the control on account of promotion effect of K. NaBrO₃ caused impediment for growth at the same concentration. As good correlation was showed between growth inhibition induced by KBrO₃ and bromate concentration, a linear regression equation was obtained. On the other hand, growth inhibition induced by NaBrO₃ was fitted well for logarithmic equation.
