当细胞分裂素(CK)应用于完整的豌豆植株时，显著降低了内源脂肪氧合酶水平。此外，研究还表明，叶片脱落引发的衰老总是伴随着脂氧合酶活性的显着增加，而CK处理显着减缓了脂氧合酶活性的增加。提示CK诱导的脂氧合酶抑制是该激素整体抗衰老作用的一种机制，这可能具有生物学意义。
Cytokinin (CK), when applied to intact pea plants, considerably lowered endogenous lipoxygenase levels. Furthermore it was demonstrated that the triggering of senescence induced by leaf detachment was invariably accompanied by a significant increase of lipoxygenase activity and the CK application considerably decelerates lipoxygenase increment. It is suggested that the lipoxygenase repression induced by CK is a contributing mechanism to the overall antisenescence action of the hormone, and that this may have biological implications.
