Abstract

Abstract: Taking the sweet potato bud seedlings of Pushu 32 as the research object, the effects of different treatments on the rooting time, rooting number, root length and cuttage survival rate of sweet potato bud seedlings were studied by different ratios and concentrations of rooting agents. The results showed that IBA （indole butyric acid） + NAA （naphthylacetic acid）, ABT and water treatment could all promote rapid rooting of sweet potato shoots. When the concentration of ABT was more than 25 mg/L, it would inhibit the rooting of sweet potato bud seedlings to a certain extent, thus reducing the number of roots. When the rooting number of sweet potato bud seedlings decreased with the increase of rooting agent dosage, the single root length did not become longer obviously, and the total root length was positively correlated with the rooting number as a whole. Cuttage of sweet potato bud seedlings after rooting could significantly improve the survival rate of sweet potato bud seedlings, and the survival rate of bud seedlings treated with each rooting agent was higher than that of the control（clean water）. The survival rate of sweet potato bud seedlings was related to the rooting number and total root length of sweet potato seedlings.

Key words: rooting powder, sweet potato[Ipomoea batatas（L.）Lam.], root length, rooting number, cuttage survival rate
