[Analysis of salt resistance on the poplar transferred with salt tolerance gene].
Poplar(Pupulus x Xiao zhannica, cv. "balizhuang-yang") transferred with mtl-D gene was used as an experimental material. Through tissue culture, aquaculture and pot culture transgenic poplars are tested with variant Nacl salt gradient. In it transgenic poplar raises its initial days for differentiation, differentiation rate, bud intensity, bud height and growth potential than control plant. At the same time, the transgenic poplar has higher rooting rate and more top roots, side roots and higher root length than control under the same salt stress. The result shows that the transgenic poplar has better tolerance ability than control plant in the salt 4@1000 contensity mediums.
