Abstract
The variation of germination characteristics were studied and compared among varieties to determine the effect of NaCl stess on seed germination of tomato.The seed germination potential,germination percentage,germination time and regularity,vigor index,salt-tolerance index and the growth of seedlings were studied.The result showed that the germination potential,germination percentage,vigor index and salt-tolerance index of two varieties decreased with the increasing of NaCl concentration;The radicle/embryo ratio deceased at low degree stress,while radicle/embryo ratio had opposite changing with the increasing of NaCl concentration.It indicated that low salt stress can promote the germination of seed,but high salt stress resulted in decreasing of seed vitality.The descent degrees had relation to different tomatoes.The seed germination time became longer and regularity became lower with the increasing of salt concentration,and the different variety had different germination time and regularity.
