摘要
对上海市固氮植物的结瘤状况和固氮效果进行调查分析,采集根瘤寄主分属5科37属,共83种,其中非豆科植物有4科4属12种,豆科植物33属71种。结果表明,有93%的根瘤着生于寄主侧根,大小一般在1~10mm。形状以球形、近球形、柱形为主,颜色多为白色、黄褐色。固氮酶活性为0~10μmol/(g.h)。
Nodulation status and nitrogen fixation were investigated. The host plants collected belong to 5 family 37 genera,totally 83 species. Among of them,33 genera 71 species were legume plants,the other 4 family 4 genera 12 species were non-leguminous plants. The results showed that 93% of root nodules ranged from 1 to 10 mm at the lateral root of hosts,with spherical or columnar in shape and white or yellowish-brown in color. Nitrogenase activity was from 0 to 10 μmol·g·h^-1.
