Abstract:
aking tomato seeds of ‘TTD302A’ as materials,five different concentrations of EMS (0.3%,0.5%,0.7%,0.9%,1.1%) were set and two different treatment time were used to induce tomato seeds,seed germination index such as germination potential,germination percentage and root length were mearsured.The results showed that there were highly significant difference of seed germination potential,the relative germination potential,germination percentage and the relative germination percentage among the treatments induced by the same treatment time and different concentrations of EMS；there were highly significant difference of seed germination potential,no significant differences of seeds relative germination potential and germination percentage,significantly different of the relative germination percentage among each treatment induced by the same concentration of EMS and different time.The median lethal dose (LD50) of EMS treatment tomato seed ‘TTD302A’ was 0.7%～0.9% EMS for 8 h.
