| 摘 要： | 构成小苍兰穗状花序的十几朵小花自花序顶瑞至基部表现出明显的发育与衰老顺序。伴随着花朵的发育与衰老，花瓣组织的可溶性蛋白质含量明显下降，细胞膜相对透性显著上升，表示膜脂过氧化水平的丙二醛含量逐渐增加，在衰老后期增加更显著，与此相对应，饱和脂肪酸所占百分比增加，脂肪酸不饱和指数ＩＵＦＡ明显下降。

| Abstract: | The degree of the development and senescene of common freesia flowersdepends obviously on their positions on the spike. During the petal senescenc,the solu-ble protein content decreased ,while the plasma membrance permeability increased. Also,a marked increase in malondialchyde(MDA),which is used as a criterion of the level ofmembrane-lipid peroxidation ,was observed. Meanwhile ,saturation of fatty aoid in-creased and the index of unsaturated fatty acid(IUFA) decreased. |
