Responses of <i>Cymbopogon schoenanthus</i> to salt stress

Abstract

Cymbopogon schoenanthus is an aromatic and medicinal plant rich in essential oil. The physiological behavior of this species, related with growth production, the photosynthetic pigments, the nutritional status and the osmotic adjustment were studied. Saline treatments varied from 0 to 150 mM NaCl. The results show that the growth of C. schoenanthus was affected by the salinity and the effect increased with more stress at 100 mM of NaCl. Besides the response of C. schoenanthus to the salt stress, this study has allowed us to conclude that this plant is excluder glycophyte and less tolerant to salt stress.

Key words: Cymbopogon schoenanthus, NaCl, growth, mineral nutrition, osmotic adjustment.
