As a result, the three kinds of reagents could inhibit the sprouting of root tuber, and the inhibition ability was CAR>MEN>CIPC. Sprouting inhibition reduced respiration consumption, which thus decreased the weight loss of root tuber, and the weight loss of CAR treatment was only 46.40% of the control weight loss after storage 150 d. Starch content in the dry matter of sweet potato root tuber showed a downward trend during storage, but the sprouting inhibition treatment could significantly keep starch content. At 150 d, the starch content of Mian 12-25-1 and Mianzishu 9 after CAR treatment was 34.57% and 24.82% higher than that of control, respectively. The consumption of soluble sugar and anthocyanin in sprouting inhibition treatment was delayed to reduce in different degrees and the ability of retarding was positively correlated with sprouting inhibiting ability. The anthocyanin content of CAR treatment in Mianzishu 9 root tuber was 22.06% higher than that of the control at 150 d. The sprout inhibition treatment had a weak effect on the α-amylase activity, but significantly stimulated the activity of POD related to stress resistance. The results demonstrated that, CAR as an environmentally friendly substance with the lower using content could effectively inhibit the sprouting of root tuber and maintain root tuber quality and had the potential to prolong the storage period of sweet potato. %U https://www.hnxb.org.cn/EN/10.11869/j.issn.100-8551.2019.03.0530
