Tuberous roots of sweet potato, belonging to clone CEMSA 78-354, coming from banks of seeds and collected, keeping in mind their sanity and uniformity in the size, were used. They were transferred to laboratory under semicontrolled conditions and placed in glass flasks with 300 mg.l -1 of tap water (control treatment) and in flasks with the some volume of water and different pectimorf concentration (5, 10, 15 and 0 mg.l -1). At different time the following indicators: number of sprouts per tuber, length of sprouts and number of buds per sprouts. Evaluated indicators were achieved with the use of 15 mg.l -1 Pectimorf overcoming those reached by the control treatment. Key words: buds, Pectimorf, sprouts, sweet potato
