| 摘 要： | 测定不同类型甜菜品种各生育时期根中Mg^2＋-ATP酶活性、可溶性总糖、可溶性蛋白含量和产量、含糖率。结果表明，在幼苗期和叶丛繁茂期，Mg^2＋-ATP活性呈先上升后下降趋势，从块根增长期直至糖分积累期，Mg^2＋-ATP酶的活性逐渐增强，并保持在全生育期最高水平。不同类型品种间存在差异，在各生育时期高糖型品种Mg^2＋-ATP酶活性较强。根中Mg^2＋-ATP酶活性与根中可溶性总糖呈正相关，与甜菜根的成熟进程正相关；Mg^2＋-ATP酶活性与可溶性蛋白质舍量呈负相关，对可溶性糖的积累方面，二者的作用刚好相反。高糖型品种的可溶性总糖含量较高．相应的根中蛋白质含量很低。Mg^2＋-ATP酶活性较高．

| Abstract: | The Mg^2＋-ATPase activity, total soluble sugar content, soluble protein content, yield and the sugar content in sugarbeet roots of different cuhivars were measured. Mg^2＋-ATPase activity was observed at first increased, and then decreased in the seedling stage and leaf epacmastic stage, from the root growth until the sugar accumulation phase, Mg^2＋-ATPase enzyme activity gradually increased and maintained at the highest level of whole growth period. The Mg^2＋-ATPase activity of the high-sugar type varieties is the strongest in the different cuhivars. The Mg^2＋-ATPase activity and the total soluble sugar content was a positive correlation, and with the maturity process of sugarbeet root is a positive correlation. Mg^2＋-ATPase enzyme activity and soluble protein content was negative correlation, but to the accumulation of soluble sugar, the role is just the opposite. In the high-sugar type varieties, the total soluble sugar content was higher while the protein content was lower and Mg^2＋-ATPase activity was higher. |
