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。
Seven hybrids of purple maize were used as materials to study grain yield, yield components, anthocyanin content, anthocyanin yield and physiological indexes. The results showed that the yield of different varieties of purple maize varied greatly. The main factors influencing the yield were the size of ear and the rate of emergence. The content of anthocyanin in different varieties was quite different. Anthocyanin content and yield There was a significant negative correlation between the content of anthocyanin and the yield of grain. There was a significant positive correlation between the content of anthocyanin and the yield of anthocyanin. There was a negative correlation between the anthocyanin content and photosynthetic rate, There was a negative correlation between the content of chlorophyll and chlorophyll content. There was no significant correlation between leaf anthocyanin content and leaf soluble sugar content during the flowering and filling stages.
