| 摘 要： | 本文对甜菜植株中锰含量的变化及其分配特点进行了初步研究.结果表明:(1)甜菜锰代谢最强的时期,是在叶丛快速生长期.这与氮、磷代谢特点相一致。生育期植株中锰的含量,因品种类型不同有所差异。(2)甜菜吸收和累积锰量最多的时期,是叶丛快速生长期至决根,糖分增长期;锰在叶中的分配量,在整个生育期都占绝对优势。(3)蔗糖与锰的含量,在叶片中存在着正相关关系;在叶柄中却呈负相关关系。

| Abstract: | The preliminary study on changes of Mn content and its partioning characteristics in sugarbeets were carried out in this paper. The results shown that 1). Maximum Mn metabolism of sugarbeet was in the stage of foliage quick growing, which was consistent with the metabolism trait of N and P. Mn content in the plants was differ from different type of CV. 2). The period when sugarbeet had maximum amount of Mn absorbing and accumulating was from the foliage quick growing stage to root and sugar increasing stage. Mn partioning to the leaf was always predominated absolutely in whole developing stage. 3). Relation between sucrose and Mn content in the leaf was positive, while negative in the petiole. |
