【摘要】 对供试18个紫色甘薯品种的主要农艺性状观察、营养品质鉴定以及加工品质和适应性进行系统分析和比较。结果显示:薯形美观,食味品质和适口性好的4个品种——福薯9号、F22-158、58009和济薯18,适合作为紫色优质食用薯开发;产量高、烘干率与出粉率适中、加工品质好的伟祥1号和济薯18适合作紫色地瓜干加工用原料薯开发;其他供试品种大多烘干率、出粉率较高,较适合用于提取淀粉或花青素。通过对地瓜加工品种伟祥1号和济薯18的叶面积系数、茎叶、块根及T/R值消长动态进行研究,发现伟祥1号作为早熟型品种在推广种植过程中应加强早期栽培管理有利于高产;济薯18属中、迟熟型品种,延长生育期,生长后期防止茎叶早衰有利于高产。更多还原

【Abstract】 In this study,comprehensive evaluation of agronomic characters,nutritional components,processing quality and adaptation in eighteen purple sweet potato varieties were carried out.The results showed that Fushu No.9,F22-158,58009 and Jishu No.18 had the characteristics of fine exterior,high quality and palatability,which are suitable for being purple sweet potato edible varieties.Weixiang No.1 and Jishu 18 has such perfimance characters as fine exterior,high quality and palatability,which are suitable for purple sweet potato processing varieties.varieties is better suited for and anthocyanidin extraction.Further study on stem-leaf yield,sweet potato yield,leaf area coefficient and T/R value of sweet potato processing varieties,we founded that strengthening management in early culture stage for Weixiang No.1 were very favorable in obtaining a high yield,but extension growth period and prevention leaf drop were conducive to the high yield of Jishu No.18.更多还原
