Effects of Paenibacillus polymyxa inoculation and different soil nitrogen treatments on lodgepole pine seedling growth

An endophytic diazotroph, Paenibacillus polymyxa P2b-2R, has been shown to colonize internal tissues of lodgepole pine and stimulate seedling growth possibly through nitrogen (N) fixation in an N-limited environment. We evaluated the effects of different soil N concentrations on lodgepole pine seedling growth after inoculation with P2b-2R in a year-long greenhouse study. Seedlings were subjected to monthly application of a nutrient solution containing one of four soil N concentrations as Ca(NO3)2 (5%The accepted manuscript in pdf format is listed with the files at the bottom of this page.
