Abstract
The effects of stress under different NaCl concentrations on seed germination in 12 tomato culti-vars were studied.The results showed that the stress under low NaCl concentrations on seed germination had cer-tain promotion;,inversely,with the increasing of NaCl concentration,the germination percentage,germination energy,germination index,and vigor index decreased,and germination time and seed germinating performance would be delayed and reduced accordingly.Under the same stress conditions,the seed germination among differ-ent tomato varieties were significantly different.
