对月季花瓣衰老过程中可溶性蛋白的ＳＤＳ－ＰＡＧＥ进行了分析，结果表明，蛋白条带变化表现出３种情况：（１）从瓶插开始到结束蛋白条带基本保持稳定；（２）随花瓣衰老，蛋白条带逐渐减弱、消失；（３）随着花的衰老，有新的蛋白条带出现。对花进行ＡＢＡ或乙烯促衰处理，也导致相应的某些蛋白条带的变化，说明这些蛋白的变化可能与衰老有关。 SDS-PAGE of the soluble proteins during the senescence of rose petals was analyzed. The results showed that there were three kinds of changes in protein bands: (1) the protein bands remained stable from the beginning to the end of vase; (2) Aging, protein bands gradually weakened, disappeared; (3) with the flower senescence, there are new protein bands appear. ABA or ethylene decay of flowers also led to the corresponding changes in some protein bands, indicating that the changes of these proteins may be related to aging.
