| 摘 要： | 多胺是一类具有强烈生理活性的低分子量含氮碱。它们不仅调节植物的生长，发育，还参与植物的胁迫反应。当植物遭受水分胁迫，酸胁迫，盐胁迫，离子胁迫，低温胁迫等各种逆境时，多胺合成酶活力增加，腐胺大量累积。

| Abstract: | The putrescine and spermidine accumulate in higher plants in response to various stresses. The rise of putrescine (Put) is paralleled by an increase in the activity of arginine decarboxylase. The Put is as an organic cation, its accumulation is a response to acidification of the cytoplasm resulting from cation/anion imbalance in order to regulate cellular pH, perhaps, Put may have a key position in nitrogen metabolism which has not been fully realized yet. |
