【摘要】 该文较为系统地阐述了品黑一号的亲本来源、选育过程、特征特性、营养品质以及重金属含量安全等相关问题,其中4个样品中硒含量变幅在0.035~0.57mg/kg,平均为0.29mg/kg,达到富硒标准;铁含量超过检测低限15%以上;锌含量超过检测低限4倍以上。经过标准化生产的黑米重金属镉含量到达检测低限以下,低于国家标准4~5倍,达到有机标准。更多还原

【Abstract】 The indica black glutinous rice variety Pinhei 1 was bred and could be used for producing functional riceproducts.In this paper,the origination of its parental lines,breeding procedure,agronomical and nutritional parame-ters was presented.The selenium content of the variety from four sources was among 0.035~0.57 mg/kg with a meanof 0.29 mg/kg,which reached the standard of selenium-fortification.Concentrations of iron and zinc were 15% and 4times above the lowest detection limits,respectively.Following the standardized production procedures,the concen-tration of cadmium,a heavy metal pollutant,was under the lowest detection limit,which was 4-5 times lower thanthe national safety limitation.Such product could be considered organic.更多还原
