Plant growth-promoting rhizobacteria: Effects on growth and nitrogen fixation of lentil (Lens esculenta moench) and pea (Pisum sativum L.)

摘要: Abstract The potential of a number putative plant growth-promoting rhizobacterial strains to enhance the growth and nitrogen fixation western Canadian cultivars lentil ( Lens esculenta Moench) pea Pisum sativum L.) was assessed in field laboratory studies. Nine were tested on single cultivar (Eston) (Trapper) field. None had any effect field, but inoculated with one or more strains, there significant increases emergence, vigor, nodulation, C 2 H reduction activity root weight. Further studies conducted two best G2-8 G11-32 cv. Eston used four vitro cultivation systems determine optimal conditions for enhancement. There variation among experiments stimulation similar that observed trials sand column system. strain under conditions, G2-8, then Laird plants higher shoot dry weights greater acetylene than control pot systems.
