不同品种紫玉米产量、花青素含量及生理指标研究

Yield,Anthocyanin Content and Physiology Indexes of Different Purple Corn Varieties

以7个紫玉米杂交组合为试材,对子粒产量、产量构成因素、花青素含量、花青素产量、生理指标等进行研究。结果表明,紫玉米不同品种间产量差异较大,影响产量的主要因子是果穗大小和出籽率;不同品种间花青素含量差异较大,花青素含量与子粒产量共同决定单位面积花青素产量;子粒花青素含量与子粒产量呈极显著负相关关系,子粒花青素含量与花青素产量呈极显著正相关关系;叶片花青素含量与光合速率呈负相关关系,叶片花青素含量与叶绿素含量呈负相关关系,开花期和灌浆期叶片花青素含量与叶片可溶性糖含量相关性不显著。

Using 7 different hybridized combinations,the grain yield,yield components,anthocyanin content,anthocyanin yield,physiology indexes,etc.of purple corn were studied.The results showed as following.The yield was highly associated with the size of ear and rate of kernel production,and there were significant differences between the different varieties of the purple corn.There were strongly different anthocyanin yields among the different varieties.Anthocyanin yields of per unit area were composed of anthocyanin content and grain yields.Anthocyanin content was significantly negatively related with the grain yield and significantly positively related with anthocyanin yield.Anthocyanin content was negatively related with photosynthetic rate and chlorophyll content in the leaf.The correlation between leaf anthocyanin content and soluble sugar content was unmarked during flowering and grain filling stages.
