| 摘 要： | 用杨树溃疡病菌感染具有不同抗病性的杨树栽培种的愈伤组织,然后在一定的时间间隔上分期取样,测定各栽培种的过氧化物酶和多酚氧化酶的活性。结果表明:各栽培种受病原菌感染后过氧化物酶和多酚氧化酶活性都有升高,但抗病品种两种酶活性的变化在时间上先于感病品种,在变化的幅度上大于感病品种。品种的抗病性与这两种酶活性呈正相关。

| Abstract: | Describes the activities of peroxidase and polyphenol oxidase on 4 poplar cultivars inoculated with Dothiordlla grdgdria The activities of both enzymes on all cultivars infected are increasing. However, the increasing of enzymic activity is higher and earlier on the resistant cultivars than that on the susceptible cultivars. The resistibility of poplar cultivars to canker are positively correlated with the activities polyphenol oxidase and peroxidase. |
