NaCl?迫下促生菌??瓜幼苗生?的促生效?

Cucumber seeds which were treated by soaking with CS-2 cell suspension, a kind of plant growth-promoting bacteria, and distilled water, planted in the matrix uniformly mixed by common soils and grass carbon ones. Then, irritation was done with four concentrations of NaCl solution, measure the peroxidase activity, the soluble protein content and proline content when the true leaf number of seedling to be four. The results indicated that peroxidase activity and soluble protein content had a better growth compared with the control respectively at the presence of NaCl stress; Whereas, proline content declined when the proportion less than 0.4% compared with the control; meanwhile, there was a negative correlation between height and the peroxidase activity.
