摘　　要：为了探讨多胺的功能,用高压液相色谱(HPLC)技术检测了大豆(Glycine maxL.)种子在成熟脱水过程中3种不同形态(游离态,f;酸可溶性共价结合态,ASCC;酸不溶性共价结合态,AISCC)多胺(腐胺,Put;亚精胺,Spd和精胺,Spm)的动态变化。结果表明:在种子成熟脱水过程中,fPut的变化不明显,而fSpd和fSpm的水平明显上升。酸可溶性共价结合态多胺(ASCC-PAs)、酸不溶性共价结合态腐胺(AISCC-Put)和酸不溶性共价结合态亚精胺(AISCC-Spd)的含量明显升高。结果表明,fSpdf、Spm、ASCC-PAs、AISCC-Put和AISCC-Spd在大豆种子成熟脱水过程中可能起重要作用。To research the function of polyamine, the change in free（f）, acid soluble covalently conjugated（ASCC） and acid insoluble covalently conjugated（AISCC）polyamines[putreseine（Put）, spennidine（Spd） and spennine （Spm）] in soybean seeds at wax-mature stage were studied with HPLC. The results indicated that in seed dehydration process, the level of fSpd, fSpm, ASCC-PAs, AISCC-Put and AISCC-Spd was increased markedly, while the change in fPut was not obvious. These results suggested that fSpd, fSpm, ASCC-PAs, AISCC-Put and AISCC-Spd played important roles in soybean seed dehydration process.
