作者盛建军,李想,张彦雪,何永美,谢春梅,祖艳群,李元（2019）在《UV-B辐射对元阳红米籽粒形态和原花青素含量分布的影响》一文中研究指出：为了阐明UV-B辐射对水稻籽粒中原花青素含量和分布的影响,通过大田原位种植元阳梯田传统水稻品种——白脚老粳,在水稻的生长期进行不同强度UV-B辐射处理(0、2.5、5.0、7.5 kJ·m-2·d-1),研究不同强度UV-B辐射对水稻籽粒形态与原花青素含量分布的影响。结果表明:UV-B辐射会抑制水稻籽粒的粒长、粒宽、千粒质量、每株籽粒生物量和产量。粒长和粒宽受到了UV-B辐射的抑制,7.5 kJ·m-2·d-1时显著下降了11.6%和5%,千粒质量和籽粒生物量会随着UV-B辐射的增强显著降低,7.5 kJ·m-2·d-1时达到最低17.41 g与20.84 g·株-1。产量在高强度UV-B辐射(7.5 kJ·m-2·d-1)下显著降低,稻壳中原花青素含量在不同UV-B辐射下呈现单峰曲线,在5.0 kJ·m-2·d-1时达到最大值4.06μg·g-1·d-1。糙米中原花青素含量在低强度UV-B辐射下无显著变化,当UV-B辐射达到7.5 kJ·m-2·d-1时显著降低。原花青素在水稻籽粒中呈现由外到内逐渐减少的规律,原花青素主要聚集在果皮和胚乳表层,不同UV-B辐射强度下,原花青素面积占比有显著差异,在垂直结构上（平行于芒和小穗轴连线）,UV-B辐射增强会抑制原花青素面积占比,在水平结构上（垂直于芒和小穗轴连线）,UV-B辐射增强会促进原花青素面积占比。UV-B辐射增强会改变籽粒结构,促进稻壳中原花青素合成,过高的UV-B辐射强度会抑制稻壳和糙米中原花青素合成。UV-B辐射会影响原花青素的分布,UV-B辐射增强原花青素水平结构上的面积占比显著高于垂直结构。
