The cell and tissue differentiation connect with PPO and PAL activities of cuttings, in the period of rooting, the PPO activities of callus are increasing. When the root just come out, it’s the highest; thereafter it’s decreasing.
6、PPO、PAL是与细胞和组织分化有关的酶，在根形成过程中PPO活性明显增加，根开始分化延伸时达到最大2.4095mg／g·min，根形成之后降低；而PAL活性则逐渐下降。
