特殊粒色小麦研究进展

目的明确彩色小麦与普通小麦在色素和品质方面的差异。方法以滇麦9号(紫粒)、滇麦10号(蓝粒)和云麦56 (白粒)为研究材料，对彩色小麦中色素、微量元素及其品质特性等进行了测定和分析。结果彩色小麦与普通小麦色素含量存在极显著差异，花青素、黄酮和叶绿素含量均高于普通小麦，其中紫粒小麦花青素含量最为突出，达普通小麦的43.5倍；彩色小麦中的微量元素锌、硒和锰的含量均远高于普通小麦，且硒元素仅在彩色小麦中检测到，其中滇麦9号硒含量为0.31 μg/g；彩色小麦中氨基酸、面筋含量和可溶性蛋白远高于普通小麦。结论研究结果为优质彩色小麦品种的选育和应用奠定理论基础和技术支撑。

Effects of different depth of grain colour on antioxidant capacity during water imbibition in wheat (Triticum aestivum L.)

PurposeTo clarify the difference in pigment and quality between color wheat and common wheat.MethodsDianmai 9 (purple-grained wheat), Dianmai 10 (bule-grained wheat) and Yunmai 56 (white-grain wheat) were used as research materials for pigments, microelements and quality characteristics in color wheat.ResultsThere were significant differences in the pigment content between color wheat and common wheat. The anthocyanins, flavonoids and chlorophyll content of the color wheat were much high than the white wheat, especially the contents of anthocyanin in the purple-grained wheat were 43.5 times of the common wheat. The contents of microelements selenium, zinc and manganese in the color wheat were much high than the white wheat, especially selenium only detected in the purple-grained wheat, of which Dianmai 9 the content selenium was 0.31 μg/g. The contents of amino acids, gluten and soluble proteins in the color wheat were much high than of the white wheat.ConclusionThe results of this study can provide a theoretical foundation and technical support for the selection and application of high-quality colored wheat varieties.
