From
the experiment results stated above, two conclusions were drawn:
1.
Sodium chloride severely inhibited plant growth. Applied in large quantities, it
could limit growth to less than 10% of the normal plant weight. It also destroys
the chance of germination when Brassica napus seeds are treated with
20g/L of salt.
2. The transgenic plants grew better than the wild-type plants under salt
stressed conditions in vegetative growth for all the four transgenic lines
tested, but only two of the transgenic lines performed better in the germination
experiment. [These two lines (line 3 and 4) were constructed the way that the
gene is expressed in all the plant tissue instead of mainly in roots (line 1 and
2)].
