摘要:
徐紫薯8号为高花青苷型甘薯新品种，生育期影响结薯习性、产量及品质性状。本试验研究 78～188 d共12个生育期下徐紫薯8号薯形、单株结薯数、大中薯率、产量、花青苷含量及淀粉含量等变化规律。结果表明，不同生育期徐紫薯8号各个性状差异显著。大中薯率、亩鲜薯产量、淀粉含量和花青苷产量随生育期延长逐渐升高；薯块长宽比、小薯率、还原糖和可溶性糖含量随生育期延长而下降。相关性分析结果表明，亩鲜薯产量与单株结薯数、大中薯率、烘干率、亩薯干产量和淀粉含量呈显著或极显著正相关。生育期148 d甘薯单株结薯数最多，亩鲜薯产量和花青苷产量均最高，分别达每667 m23 927.00 kg和425 kg，大中薯率达90%，甘薯商品性好，食用品质佳。
Abstract:
Xuzishu8 is a new sweetpotato cultivar with high anthocyanidin. The growth stage affects its tuber traits, yield and quality. Changes of the ratio of length/wide, storage root per plant, yield, anthocyanidin content and starch content were studied under different growth stage from 78 d to 188 d. The results showed that the traits of Xuzishu8 in different growth stages were significantly different. Commercial sweetpotato ratio, fresh sweetpotato yield, starch content and anthocyanidin yield increased with the extension of growth stage, while the length/width ratio, small sweetpotato ratio, reducing sugar content and soluble sugar content decreased with the extension of growth stage. The results of correlation analysis showed that there was a significant positive correlation among the fresh sweet potato yield and the number of tubers per plant, commercial sweet potato ratio, dry mattet content, dry yield and starch content. The maximum number of tubers, highest fresh yield and anthocyanin yield were dotained at 148 d of growing period, the fresh yield and the anthocyanin yield were 3 927.00 kg per 667 m2 and 425 kg per 667 m2, respectively, the commercial sweetpotato ratio reached 90%. Xuzishu8 has good commodity and edible quality.
