甜菜细胞质雄性不育系与其保持系游离脯氨酸含量的差异

Differences of Proline Content in Cytoplasmic Male Sterile Lines and Maintainer Lines in Sugarbeet

以甜菜3个细胞质雄性不育系及其相应保持系为材料,对营养生长阶段叶片中的脯氨酸含量进行了研究。结果表明:在甜菜营养生长阶段的4个时期中,脯氨酸含量基本表现为保持系高于不育系。说明不育系和保持系在营养生长阶段生理生化代谢上已经存在差异。

Proline content of leaves from three cytoplasmic male sterile lines and their maintainer lines in sugarbeet were studied during their vegetative growth stage. The results showed that the proline content of leaves from the maintainer lines were higher than those from the sterile lines. This result also indicated that there were significant differences between maintainer lines and the sterile lines on physiological and biochemical properties during their vegetative growth stage.
