以从白杨杂种741杨内生菌中提取得到的菌株P22和S16为研究对象，通过16S rDNA分子检测证明它们分别属于类芽孢杆菌（ Paenibacillus sp．）和寡养食单胞菌（ Stenotrophomonas sp．）。研究了菌株P22和S16对促进近缘种植物生根及生长的能力。结果表明：菌株P22和S16对三倍体毛白杨组培苗、欧美杨107和旱柳硬枝插条生根和生长促进作用显著。证明这2株菌株为植物促生菌，可能具有固氮和诱导产生植物激素的作用，菌株P 22的促进生长能力更加显著。

We isolated Paenibacillus (P22) andS tenotrophomonas (S16) from Endophytic bacteria of the hybrid poplar 741. They respectively belonged to Paenibacillus sp.and Stenotrophomonas sp.by 16S rDNA molecular detection .Then, we studied the ability of strains P 22 and S16 for promoting rooting and growing on sibling species plants .P22 and S16 remark-ably promoted rooting and growing of tissue culture seedlings of Triploid Populus tomentosa and hardwood cuttings of Popu-lus×canadensis ‘Neva’ and Salix matsudana.Two strains were plant growth-promoting bacteria, and they might have the functions of nitrogen fixation and inducing generation of plant hormones .The capacity of promoting growth of P 22 was more remarkable .
