与会者对共同利益的认识是从最近在三个领域取得的进展中发展而来的。在国际生物学计划（IBP）的推动下，在G。在苏格兰格拉斯哥大学的BOND教授的指导下，人们进行了认真的努力，以建立一个世界范围内的不同植物群体的统计，这些植物由于其根系的放线菌感染而具有共生固氮能力。在1976年由PS NUTMAN（剑桥大学出版社）编辑的IBP卷中，邦德的统计表明，属于7个科15个属的160种双子叶植物组成了一个令人惊讶的多样化群体，除了对放线菌感染的敏感性外，几乎没有共同特征。共生固氮bv这一组合的植物的意义来认识到，这些生物体，总的来说，能够固定大气中的氮的速率相当的豆科Rhisobium系统，测量单个鲜重或干重的基础上使用率15 N固定或乙炔还原测量或计算从现场数据公斤每公顷的基础上。对于世界南北温带地区来说，这种固定是巨大的，需要得到更广泛的充分理解和认识。
Recognition of the common interests of the group assembled evolved from recent strides made in three areas. Through the stimulus of the International Biological Program (IBP) over the past decade and under the leadership of Professor G. BOND of the University of Glasgow, Scotland, serious efforts had been made to establish a worldwide accounting of the diverse groups of plants which possess symbiotic nitrogen-fixing capacity due to actinomycete-infection of their root systems. In the IBP volume in 1976, edited by PS NUTMAN (Cambridge University Press), BOND'S tally showed that 160 species of-vvoody dicots, belonging to 15 genera among seven families, make up a surprisingly diverse group which shows few common features other than susceptibility to infection by actinomycetes. The significance of symbiotic nitrogen fixation bv this assemblage of plants came with the recognition that these organisms by and large were capable of fixing atmospheric nitrogen at rates comparable to the legume-Rhisobium systems, measured on an individual fresh weight or dry weight basis using rate of l5N-fixation or acetylene-reduction measurements or calculated from field data on a kilogram per hectare basis. For north-and south-temperate regions of the world, the fixation is of large magnitude and needs to be fully understood and appreciated more widely.
