- 摘要:
- 以‘JF544’（国家番茄种质资源圃提供）、‘LA1579’（醋栗番茄，L.pimpinellifolium）、‘LA0407’（多毛番茄，L.hirsutum esp glabratum）和‘LA2711’（Edkawi品种，美国番茄遗传研究中心提供）几种不同基因型番茄为试材，设置了5个NaCl浓度梯度，检测盐胁迫下种子发芽率和苗期叶片相对电导率、脯胺酸含量变化及其生物量和根变化，以期对不同品种番茄的耐盐性进行筛选。结果表明：在种子萌发期表现最好的是‘LA0407’，其次是‘JF544’、‘LA2711’和‘LA1579’。在苗期表现最好的是‘LA2711’，其次是‘LA0407’、‘LA1579’和‘JF544’。番茄植株在盐胁迫下的反应不仅与其本身耐盐性有关，也与植株的营养状态和植株大小相关。
- 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.
