Concentrations of carbon bisulfide on sprouting of potato mini tubers was evaluated. The study was set as a factorial experiment. The treatments were composed of four concentrations of carbon bisulfide (10; 20; 30 and 40 mg L-1) besides the control and seven potato cultivars (Bintje, Jaete Bintje, Atlantic, Cupido, Agata, Monalisa and Mondial). The potato mini-tubers were treated with carbon bisulfide during 72 hours in a closed recipient and then allowed to sprout. All concentrations of carbon bisulfide enabled the potato sprouting. Bintje and Atlantic tubers increased sprouting under higher carbon bisulfide concentrations. Tuber sprouting of Agata and Mondial did no respond to carbon bisulfide concentrations over 10 mg L-1. Jaete Bintje and Monalisa presented the best results when 20 and 30 mg L-1 of carbon bisulfide was used.
