| 摘 要： | 采用完全随机区组设计,用马尾松(Pinusmassoniana)、木荷(Schimasuperba)、赤楠(Syzygiubuxifolium)、杉木(Cunninghamialanceolata)的枝叶1∶6浓度水浸液和清水共5个不同处理浇灌盆栽的杉木幼苗,2a后对其叶片的硝酸还原酶活性进行测定。结果表明,经过几种杉木伴生种水浸液处理2a后杉木的硝酸还原酶活性比杉木水浸液及清水处理的有较大程度的提高,其中经过马尾松水浸液处理的杉木叶片的硝酸还原酶活性最高,而经杉木枝叶水浸液处理的硝酸还原酶活性最低。

Effects of Water Extracts of Several Tree Species on the Nitrate Reductase of Cunninghamia lanceolata Blade |
| |
| Abstract: | The results showed that the nitrate reductase activity of Cunninghamia lanceolata treated with water extracts of several C.lanceolata auxiliary species increased in a large degree as compared with the C.lanceolata water extract and clear water,among the activities that treated with Pinus massoniana water extract is highest,whereas that treated with C.lanceolata branch and leaf water extract is lowest. |
