| 摘 要： | 以渝苏紫43等3个品种为材料,采用4种遮荫处理,并于栽后不同时间挖根测定块根鲜质量及花色苷含量,研究遮荫对紫肉甘薯块根鲜质量、花色苷含量及产量的影响.结果表明,不同品种栽后153 d,单层遮荫处理使块根鲜质量降低23.33%~76%,块根花色苷含量提高32.72%~49.07%,块根花色苷产量降低32.74%~66.28%;双层遮荫整体上增强了单层遮荫的效果.因此,紫肉甘薯最适宜净作.单层或双层遮荫时,渝苏紫43或渝紫263鲜薯或花色苷产量最高.在麦-玉-苕耕作制度下,以收获鲜薯为目的,渝紫263较适与玉米等作物套作,渝苏紫43次之;以获得花色苷为目的,渝苏紫43较适,渝紫263次之.遮荫处理对块根鲜质量和花色苷含量的影响主要表现在生长前期(栽后1~25 d).

| Abstract: | The effects of shading on fresh weight,anthocyanin content and yield of the storage root of three purpled-fleshed sweetpotato varieties,'Yuzi 263','Yusuzi 43' and 'Yamagawamurasaki',were studied in the present paper.The seedlings of the 3 varieties were treated by four shading levels after transplanting.As was shown by determination made 153 d after transplanting,one-layer shady light condition resulted in an increase in anthocyanin content in the storage roots by 32.72% to 49.07%;however,the fresh weight o... |
