摘要: 选用12个浙江省甘薯主栽品种,分析其块根草酸含量、单宁含量、胰蛋白酶抑制剂活性,并筛选代表性甘薯,研究相同扦插期、不同收获期及不同扦插期、相同收获期下不同生育期(80、100、120、140、160 d)对甘薯块根草酸含量、单宁含量、胰蛋白酶抑制剂活性的影响,为甘薯抗营养因子调控提供理论依据。结果表明,不同甘薯品种块根抗营养因子含量(活性)差异明显,3个紫薯品种块根的草酸、单宁含量均显著高于其余甘薯品种,白心甘薯块根的草酸、单宁含量较低,黄心甘薯块根的草酸、单宁含量最低。根据聚类分析结果及市场推广情况选取心香、越南紫薯、浙薯75进行后续研究。心香、越南紫薯、浙薯75块根的抗营养因子含量(活性)随着生育期延长变化趋势如下:相同扦插期(5月1日)、不同收获期时,收获期在8月10日至9月1日,即控制生育期为100~120 d,能明显控制甘薯块根内草酸及单宁含量;收获期为10月10日,即生育期为160 d,能明显控制甘薯块根内胰蛋白酶抑制剂活性。不同扦插期、相同收获期(10月10日)时,扦插期为5月20日,即生育期为140 d,能明显控制甘薯块根内草酸含量及胰蛋白酶抑制剂活性;扦插期为6月10日时,即生育期为120 d,能明显控制甘薯块根内单宁含量。

Abstract: Twelve major sweet potato varieties from Zhejiang Province were selected to analyze oxalic acid content,tannin content and trypsin inhibitor activity of tubers,and representative sweet potato varieties were screened to study the effects of different growth periods(80,100,120,140 and 160 d)on oxalic acid content,tannin content and trypsin inhibitor activity of tubers under different cutting stages or harvest stages,so as to provide theoretical basis for the regulation of antinutritional factors of sweet potato.The results showed that antinutritional factor contents(activities)of tubers of different sweet potato varieties were obviously different,the oxalic acid and tannin contents of tubers of three purple varieties were significantly higher than those of the other sweet potato varieties,the oxalic acid and tannin contents of tubers of white sweet potato varieties were lower,and those of tubers of yellow sweet potato varieties were the lowest.Xinxiang,Yuenanzishu and Zheshu 75 were selected to do the follow⁃up study according to cluster analysis and market promotion. The content(activity)of antinutritional factors changed as the growth period prolonged. When cutting was on May 1,harvest from August 10 to September 1 with growth periods of 100—120 d obviously controlled the oxalic acid and tannin contents of sweet potato tubers,and harvest on October 10 with growth period of 160 d obviously controlled the trypsin inhibitor activity ofsweet potato tubers. When harvest was on October 10,cutting on May 20 with growth period of 140 dobviously controlled the oxalic acid content and trypsin inhibitor activity of sweet potato tubers,and cutting on June 10 with growth period of 120 d obviously controlled the tannin content of sweet potato tubers.

Key words: Sweet potato tuber, Growth period, Cutting stage, Antinutritional factor, Varieties difference
