| 摘 要： | 目的]为了掌握糖分积累动态的变化。方法]以青芋2号菊芋为试验材料，采用Hoagland营养液培养法，研究菊芋苗期茎叶糖含量的变化动态。结果]在氮磷钾缺乏处理下，菊芋苗期叶片、茎部果聚糖含量均增加，高于对照；叶片中蔗糖含量均高于对照；还原性糖葡萄糖、果糖含量均低于对照。结论]氮、磷、钾缺乏处理对菊芋苗期茎、叶片果聚糖含量的影响是一致的。

| Abstract: | Objective ] The research aimed to study the dynamic change of sugar content and accumulation. Method ] Using Qingyu2 as ma- terial, Hoagland nutrient solution culture method was adopted to explore dynamic change of sugar content in stems and leaves during seedling time. Result] In the seedling time, the fructan content of the lack of N, P, K were higher than that of CK in leaves and stems, and the su- crose content was higher than that of CK in the leaves. However, the reducing sugars content and fructose were lower than that of CK. Con- clusion ] The effects of lack of N, P, K on the content of fructose in stems and leaves during seeding time were consistent. |
