外源甜菜碱对盐胁迫下盐角草和毕氏海蓬子萌发及幼苗生长的影响
Effects of exogenous GB on germination and seedlings of Salicornia Europaea L. and Salicornia Bigelovii Torr. under NaCl stress
摘要
Abstract
Effects of exogenous GB on seed germination and seedling growth of Salicornia bigelovii Torr. and Sal-icornia 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 Salicomia 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.关键词
