【摘要】 紫色马铃薯、紫色甘薯等紫色作物富含天然抗氧化活性物质——花青素而受到消费者的青睐。为推动紫色马铃薯、紫色甘薯的进一步发展,本研究收集了部分有关马铃薯、甘薯等作物花青素合成和积累的研究报道和数据,对施肥(氮肥、磷肥、钾肥、硒肥、有机肥、复合肥)、种植技术(密度、收获期、覆盖方式、遮荫、海拔高度)、外源物质(糖类、激素类、生根粉)等栽培因子调控马铃薯、甘薯等作物地下部块茎、块根中花青素合成进行了分析,并探讨了其研究方向,为紫色马铃薯、紫色甘薯花青色合成的深入研究提供借鉴。更多还原

【Abstract】 Purple potato, purple sweet potato and other purple crops are rich in anthocyanin, which is regard asa natural antioxidant, thus are favored by more and more consumers. In order to promote the production ofpurple potato and purple sweet potato, the data related to the regulating effect of cultural factors, such asfertilization(nitrogen, phosphate, potassium, selenium, organic and compound fertilizer), planting technique(density, harvest period, cover pattern, shading, altitude) and exogenous substances(sugar, hormones, rootingpowder), on anthocyanin biosynthesis mechanism in potato tuber and sweet potato root were analyzed. Theresearch direction and application prospects of anthocyanin biosynthesis in purple potato and purple sweetpotato were also discussed. This paper would provide reference for further research on anthocyaninbiosynthesis.更多还原
