全紫株甜荞花青素积累研究
Anthocyanin Accumulation of All-Purple Common Buckwheat Plants
摘要
Abstract
In this study,the high-anthocyanin common buckwheat line'QZZTQ'(all-purple plant)was selected to investigate the changes and spatiotemporal distribution characteristics of anthocyanins in buckwheat at different growth stages under different light intensities.The results showed that:(1)In the flowering stage of the all-purple common buckwheat('QZZTQ'),the anthocyanin content in the flower and leaves was significantly higher than that in other organs,indicating that the flower and leaves are excellent materials for extracting natural antioxidants.(2)The anthocyanins mainly accu-mulated in leaves at the seedling stage,whereas they primarily accumulated in floral organs at the flowering stage.(3)The anthocyanin composition of'QZZTQ'exhibited organ specificity.Floral or-gans and leaves mainly contained cyanidin-3-O-glucoside,while cotyledons and stems primarily con-tained cyanidin-3-O-rutinoside.(4)The anthocyanin content in the cotyledons of'QZZTQ'increased with increasing light intensity.This study elucidates the spatiotemporal distribution and accumulation characteristics of anthocyanins in the all-purple common buckwheat('QZZTQ'),providing theoretical guidance for breeding functional common buckwheat varieties and utilizing high-value organs(e.g.leaves and floral organs).关键词
