Consideration of the formulation of Murashige and Skoog (1962) medium and the published work on the relationship of cobalt and plant growth led to a study of the effect of cobalt on the growth of three species in tissue culture. Passiflora mollissima Bailey exhibited reduced viability and increased leaf abnormalities in the absence of cobalt, due possibly to the increased level of ethylene, while Saintpaulia ionantha Wendl. had an increased growth rate and plantlet numbers in the absence of cobalt. Brassica oleracea L. produced, in the absence of cobalt, fewer plantlets and abnormal leaf structures. The results indicate that the effect of low (10-7 M) concentrations of cobalt varies with species, and that inhibitory effects on growth and plantlet production can occur.
