Salt tolerance of 14 tomato（Lycopersicon exculentum Mill.）genotypes at seed germination stage and

seedling growth stage were evaluated in this experiment.During germination stage,clustering analysis was

conducted on relative germination trend and relative germination percentage of tomato seed,and 14 tomato

genotypes were divided into two groups.The first group of 5 tomato genotypes held high tolerance to salt

stress,while the other 9 were moderate tolerant.During seedling growth period,clustering analysis was

conducted on salt stress for five indicators including salt injury index,relative electric conductivity of

leaf,relative stem diameter,relative dry weight of stem and leaf,relative dry weight of root.Among the 14

tomato genotypes,4 had strong salt-tolerance and 10 had weak salt-tolerance.The results showed the salt-

tolerance of two tomato growth stages(seed germination stage and seedling growth stage)were not exactly

coherence.
