| 摘 要： | 开花前叶面喷施６－ＢＡ和ＫＨ２ＰＯ４为主要成分的复合化学制剂可以明显提高花朵鲜重，增加株高和花茎长度；在开花中后期能使叶绿素、可溶性蛋白质含量以及花瓣含水量维持较高水平；处理后花瓣中的ＳＯＤ、ＣＡＴ和ＰＯＤ３种保护酶活性明显高于对照，ＭＤＡ含量则相对较低。且花朵衰老过程中ＳＯＤ和ＣＡＴ活性变化与ＭＤＡ的累积呈显著负相关。

| Abstract: | The spray of compound chemicals mainly composed of 6-BA and KH2PO4
on tulip leaf can obviously increase the flower fresh weight and the heights of plants and
the flower stalks before flowering and can maintain the contents of chlorophyll, soluble
protein and the water content in flowers to high levels in the middle and late flowering
seasons.The protective enzyme activities of SOD,CAT and POD in flowers in the treatment aremuch higher than those in the control, except that the MDA content is lower.
Also, the paper indicates that the activity change of the 3 kinds of protective enzymes
during the flower senescence has a negetive correlation with the accumulation of MDA. |
