Influence of salt concentration on germination of different tomato seeds

The germination of seeds was significantly inhibited when 5 cultivars with different salt tolerance were cultured under 50, 100, 150, 200, 250, 300 mmol·L-1 NaCl stress. The germination energy, germination percentage, the germination index and the germination vigor index of 5 cultivars were significantly different, but there were some relations among them and they behaved the same on the whole.
