The time course and spatial distribution of wound-induced activities of phenylalanine ammonia-lyase and peroxidase were determined to establish correlations between molecular and cellular aspects of the wound-induced pattern of cell differentiation in potato (Solanum tuberosum L.) tissue. A high correlation between peroxidase activity and suberization was observed. Peroxidase activity increased for several days after wounding. Peroxidase content of suberizing cells was more than 10 times higher than that of the immediately adjacent dividing cells. Suberizing and dividing cells contained different isoperoxidases. Neither time course nor spatial distribution of the wound-induced activity of phenylalanine ammonia-lyase was directly correlated with the wound-induced pattern of cell differentiation.
为了确定马铃薯（Solanum tuberosum L.）组织中伤诱导的细胞分化模式的分子和细胞方面之间的相关性，测定了苯丙氨酸解氨酶和过氧化物酶的诱导活性的时程和空间分布。观察到过氧化物酶活性与木质化之间存在高度相关性。伤后数天过氧化物酶活性增加。木质化细胞的过氧化物酶含量比紧邻的分裂细胞高 10 多倍。木质化细胞和分裂细胞含有不同的同工过氧化物酶。苯丙氨酸解氨酶诱导活性的时程和空间分布均与伤诱导的细胞分化模式没有直接相关性。
