不同激素对红花子叶外植体过氧化物酶、酯酶同工酶和过氧化物酶、转化酶活性的影响

在 IAA、2,4-D 和 BA 作用下,红花子叶外植体过氧化物酶活性发生变化而同工酶谱带无显著改变,2,4-D 和 BA 显示对酶活性的累加促进效果。不同激素均可诱导红花子叶产生特异的酯酶同工酶酶谱。转化酶与激素所诱导的子叶外植体膨胀生长有密切联系。

DIFFERENT PLANT HORMONES' EFFECTS ON THE ISOZYMES OF PEROXIDASE AND ESTERASE AND ON THE ACTIVITY OF PEROXIDASE AND INVERTASE IN EXPLANT OF SAFFLOWER COTYLEDON

The peroxidase activity of explant of safflower cotyledon was influenced by IAA,2,4-D and BA while the isozyme bands were not remarka- bly affected.There was an accumulative acceleration on the activity of pero- xidase by BA and 2,4-D.All the different hormones can induce the cotyledon to produce a characteristic esterase isozyme pattern.There was a close relati- onship between the hormone-inducing expansion growth of cotyledon explant and the invertase activity.
