Peroxidase (EC 1.11.1.7) activity is associated with suberization during endodermal development and metacutization in roots of white spruce (Picea glauca [Moench] Voss) seedlings. Histochemical analysis indicates a relationship between suberization and peroxidase activity, but peroxidase is ubiquitous. Increased peroxidase activity results from the induction of four anodic peroxidase isozymes in addition to quantitative increases in two anodic peroxidase isozymes. Four of these polymerized eugenol. Cold temperatures induce formation of two anodic isozymes and result in suberization. The increased peroxidase activity associated with suberization is correlated to residual respiration. In an attempt to elucidate this relationship, the effect of respiratory inhibitors on respiration and peroxidase activity are compared.
过氧化物酶（EC 1.11.1.7）活性与白云杉（Picea glauca [Moench] Voss）幼苗根的内皮层发育和次生表皮形成过程中的栓质化有关。组织化学分析表明栓质化与过氧化物酶活性之间存在关联，但过氧化物酶普遍存在。除了两种阳极过氧化物酶同工酶的数量增加外，四种阳极过氧化物酶同工酶的诱导导致过氧化物酶活性增加。其中四种使丁香酚聚合。低温诱导两种阳极同工酶的形成并导致栓质化。与栓质化相关的过氧化物酶活性增加与残余呼吸相关。为了阐明这种关系，比较了呼吸抑制剂对呼吸和过氧化物酶活性的影响。
