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.
