| 摘 要： | 叶片老化期间，蛋白质的丧失是一个早期事件。在许多植物离体叶片暗诱导和连体叶片老化试验中，发现蛋白质的下降与内肽酶活力上升有关〔２，４〕。因此，研究叶片老化期间内肽酶活力上升的影响因素将有助于对叶片老化机制的进一步了解，从而对延缓叶片老化进程有重要意义...

| Abstract: | Studies with actidione, amino acids(serine, cysteine), hormone(BA, ABA) and H2O2 showed that BA and actidione could prevent the rise of endopeptidases activity, while cysteine, serine and ABA could enhance it. In addition, H2O2 played a role in enhancing the rise of endopeptidases activity. The treatment with actidione(an inhibitor of protein synthesis) also showed that there was endopeptidases synthesis during aging. |
