摘要：

研究了外源甜菜碱(GB)对不同盐(NaCl)浓度处理下毕氏海蓬子和盐角草种子萌发及幼苗生长的影响。结果表明:外源甜菜碱提高了盐环境下毕氏海蓬子和盐角草种子的发芽率、发芽指数以及活力指数。在外源甜菜碱处理下,毕氏海蓬子和盐角草幼苗根茎长及叶绿素含量都高于单盐处理,表明外源甜菜碱提高了毕氏海蓬子和盐角草抗盐能力。甜菜碱对毕氏海蓬子种子萌发率、发芽势的促进作用更大,而对于促进幼苗根茎的生长及提高活力指数和耐盐性方面对盐角草的作用更为明显。

摘要：

Effects of exogenous GB on seed germination and seedling growth of Salicornia bigelovii Torr.and Salicornia europaea L.under different concentrations of salt(NaCl) stress were studied.The results showed that exogenous GB promoted the germination capacity,germination index and seed vigor index of Salicornia bigelovii Torr.and Salicornia europaea L .under salt stress.Under the treatment of exogenous GB,the length of roots and stems and the chlorophyll content were higher than that of salt stress.The exogenous GB was beneficial to the growth of Salicornia bigelovii Torr.and Salicornia europaea L.under salt stress.In addition,it was also found that the seed germination rate and germination capacity of Salicornia bigelovii Torr.were more significantly improved than that of Salicornia europaea L.under the treatment of exogenous GB,but the length of roots and stems,the salt-tolerance and the seed vigor index of Salicornia europaea L.were more significantly improved than that of Salicornia bigelovii Torr.
