Germinative responses to salt stress in salt-marsh plants

Abstract

We found out that seeds of all species selected from the same type of habitats “malladas” germinated better in absence of salt. In all cases, with exception of Juncus subulatus, germination percentages were significantly different in control as compared to saline treatments. Seeds of the species selected were able to germinate after passing through a period of exposure to salt stress. The results obtained are in agreement with the ecology of the species. They inhabited a specific environment, the so-called “malladas” that are small endorheic basins in coastal areas, characterized by variable salinity. Interesting were the results obtained in the second stage of the experiment, in the recovery of germination. As we were able to detect some species germinate even better after such previous exposure.
