摘要
研究了刺槐(Robinia pseudoacacia)、国槐(Sophora japonica)一年生幼苗根系固氮酶活性的季节性变化,并且通过植物离体根尖接种根瘤菌试验和分析植物根系分泌物反映了国槐、刺槐根系固氮的某些特性。
The seasonal fluctuations in nitrogenase activity associated with the root systems of seedlings of Robinia pseudoacacia and Sophora japonica is here reported. Some characteristics of the nitrogenase activity in the two species are also discussed. Six species of Rhizobium attached to excised roots were inoculated and analysed, revealing the root exudates role in nitrogenase activity.
