Abstract:
With four different varieties that were ‘JF544’（National tomato germplasm resowrles garden provide）,‘LA1579’（L.pimpinellifolium）,‘LA0407’（L.hirsutum esp glabratum）and ‘LA2711’（Edkawi variety，the United States tomato genetic research center provide） as materials，under the stress of 5 concentration levels of NaCl，the change of seed germination rate，relative electric conductivity，proline content，relative growth and root weight were studied，in order to understand the response of different varieties of tomato to salt tolerance.The results showed that ‘LA0407’ was better in seedling stage，and secondly that were the tomato ‘JF544’，‘LA2711’and ‘LA1579’,‘LA2711’ was better in sprout stage，and secondly that were the ‘LA0407’,‘LA1579’ and ‘JF544’.The response of tomato under salt stress was not only related to the self salt-tolerance，but also related to the size and nutritional status of plants.
