Changes in secondary metabolites in the halophytic putative crop species Crithmum maritimum L., Triglochin maritima L. and Halimione portulacoides (L.) Aellen as reaction to mild salinity

Changes in secondary metabolites in the halophytic putative crop species Crithmum maritimum L., Triglochin maritima L. and Halimione portulacoides (L.) Aellen as reaction to mild salinity

It is assumed that salinity enhances the concentration of valuable metabolites in halophytes. The objective was to find a salt concentration and a point in time at which the yield for the valuable metabolites was maximal. Therefore, three different halophyte species were grown under different salinities and harvested over a period from shortly after stress induction up to three weeks. Various r...

Mercury intracellular partitioning and chelation in a salt marsh plant, Halimione portulacoides (L.) Aellen: strategies underlying tolerance in environmental exposure.

In the presence of metal stress, plants can resort to a series of tolerance mechanisms. Therefore field studies should be undertaken in order to evaluate the real role of these mechanisms in stress coping. The aim of this paper was to clarify the biochemical processes behind mercury tolerance in Halimione portulacoides (L.) Aellen (Caryophyllales: Chenopodiaceae) collected in a mercury contamin...

Antioxidant Enzyme Activities as a Tool to Discriminate Ecotypes of Crithmum maritimum L. Differing in Their Capacity to Withstand Salinity

Alleviation of Salt-induced Seed Dormancy in the Perennial Halophyte Crithmum Maritimum L. (apiaceae)

Crithmum maritimum L. (Apiaceae) is a perennial local oilseed halophyte. For a better understanding of the eco-physiology of salt tolerance at the germinative stage of this species, we investigate here the effects of nitrate, thiourea, and priming on its seed germination under saline conditions. Germination was strongly inhibited by increasing salinity. While nitrate supply was effective in all...

Chemical Composition, Antioxidant and Anti-acetylcholinesterase activities of Tunisian Crithmum maritimum L

acetylcholinesterase properties of the aerial parts and roots essential oils from Crithmum maritimum L., Apiaceae, gathered in the area of Monastir (Tunisia). The essential oils have been analysed by GC and GC-MS. Remarkable differences were found between the constituent percentages of the different studied organs. The most important compounds from the aerial parts were: γ-terpinene (39.3%), me...
