Free- and bound-polyamine levels were estimated in successive segments of the mung-bean hypocotyl. Three aliphatic polyamines (putrescine, spermidine and spermine) were found in proportions which depended on the state of maturation. In young cells, most of the polyamines were located in the protoplasm whereas in older cells they were mostly bound to the cell walls. Spermidine was always the main bound polyamine, and putrescine, the main free polyamine.
游离态和结合态多胺水平在绿豆下胚轴的连续节段中进行了评估。三种脂肪族多胺（腐胺、亚精胺和精胺）的比例取决于成熟状态。在年轻细胞中，大部分多胺位于细胞质中，而在较老的细胞中，它们主要与细胞壁结合。亚精胺一直是主要的结合态多胺，腐胺是主要的游离态多胺。
