- First, bacteria of the genera Rhizobium or Bradyrhizobium infect root hairs of legumes and induce formation of root nodules where the bacteria proliferate. 首先，根瘤菌屬或慢生根瘤菌屬的細菌侵染豆科作物根毛並在根毛內增殖形成根瘤。
- The root nodules are formed after the symbiotic bacteria Rhizobium invades root hairs.Legume photosynthesis provides the energy that drives the BNF symbiosis. 根瘤是共生細菌（根瘤菌屬）侵入根毛后形成的，豆類作物光合作用為共生固氮共生體提供能量。
- In addition to legumes, several genera of nonleguminous trees, including alder and ginkgo, possess nitrogen-fixing root nodules at some stages in their life cycle. 除了豆類之外，有一些非豆類植物，如赤楊和銀杏，在它們生活史的某些階段也會出現能固氮的根部根瘤。

- Experiments carried out with wheat are reported in this paper. It showed that wheat root nodules could be induced by a certain concentration of 2,4-D, however, no nitrogenase activities of these nodules were examined by acetylene reduction method. 本文以小麥為試驗材料,觀察到一定濃度的2,4-D雖能誘發小麥根部結瘤,但結瘤后的小麥植株生長受到明顯抑制,用乙炔還原法測不出這些麥瘤具有固氮活性。
