转OsEBP-89基因水稻芽期与幼苗期的抗盐性鉴定

Salt Tolerance of OsEBP-89 Transgenic Rice in Germination Period and Early Seedling Stage

以100 mmol浓度NaCl盐胁迫,对转OsEBP-89基因水稻T6代3个株系芽期与幼苗期抗盐性进行了鉴定。结果表明,转OsEBP-89基因株系之间抗盐性存在差异,其中两个转基因株系(3448和3463)发芽势比对照日本晴高,芽期综合相对盐害率显著低于对照日本晴,说明转基因材料在100 mmol NaCl胁迫下其芽受到盐的伤害少于对照材料;但其发芽率、根长、苗高和幼苗期综合相对盐害率与对照日本晴没有显著差异。

The salt tolerance of OsEBP-89 transgenic rice in the germination period and early seedling stage was studied in the condition of 100 mmol NaCl concentration. The results showed that the germination vigor of the two transgenic lines（3448 and 3463） was higher than the wild-type. The relative salt damage rate of these two transgenic lines in germinating period is lower than the contrast.But there is no significant difference in germination rate, root length and seedling height and relative salt damage rate of early seedling stage between transgenic lines and the wild-type.
