The Chinese Academy of Agricultural Sciences (CAAS) is a national, integrative agricultural scientific research organization with responsibility for carrying out both basic and applied research, as well as research into new technologies impacting agriculture. CAAS is dedicated to overcoming a broad range of challenges impacting agricultural development and support of the local rural economy. Importantly, CAAS promotes sustainable agriculture within and outside China, extending its reach through technology exchange and cooperative research agree [...]

栽培稻品种豫南黑香糯的叶鞘和颖果分别呈紫色和紫黑色,并且其颜色在整个生长发育过程中呈现不同的变化.本实验对形成颜色差异的花色素、原花色素和黄酮在叶鞘和颖果中的含量分别进行了测定.结果表明:在叶鞘部位花色素、原花色素和黄酮随着生长发育过程含量变化呈S型曲线.在分蘖期花色素和黄酮含量最高,分别为27.104 1 U/g、6.982 6 g/kg,而在拔节期时原花色素含量最高,达到149.0104 g/kg;在颖果部位上述物质则呈直线上升趋势,成熟期花色素、原花色素和黄酮的含量最高,分别为52.6193 U/g、472.3193 g/kg、31.1150g/kg.在叶鞘中相关性分析表明:花色素和原花色素呈显著水平(R=0.911*),花色素与黄酮达极显著水平(R=0.982**);然而在颖果中相关性未达到显著或极显著水平.说明在叶鞘中控制颜色的表现主要是花色素、原花色素和黄酮,在颖果中除了上述物质影响颜色的表达外还受光照、温度等环境因素影响,其深层次的调控机理有待进一步的探讨.
