Abstract

![CDATA[The mechanisms by which mature salt-tolerant plants survive in saline environments are relatively well understood. However, little is known about how seeds survive and germinate in high-salt habitats. To explore seed salt-tolerance, seeds of Ficinia nodosa (salt-tolerant) and Spyridium globulosum (salt-sensitive) were exposed to sodium chloride solutions and the amount of sodium imbibed was determined using flame photometry. The distribution of sodium and chlorine within seed tissues was investigated using X-ray mapping. Salt tolerant seeds of F. nodosa excluded sodium, whereas salt-sensitive seeds of S. globulosum accumulated sodium and chlorine in seed embryos. Exclusion of sodium may be necessary for germination and survival in saline environments.]]
