Abstract
Considering the increasing trend of saline land enhancement and lack of appropriate agricultural lands, identifying salt resistant plants such as fenugreek, which is an important medicinal plant, is important. To do so, a factorial experiment was conducted in the form of randomized complete blocks design with three replications on three fenugreek landraces (Yazd, Shiraz and Hendi) and five salinity levels (0, 40, 80, 120 and 160 mM NaCl) in hydroponic culture in greenhouse of College of Agriculture, Shahrekord University. The results showed that plant height, root length, shoot dry weight, root dry weight, and number of leaves per plant was reduced with the increase of salinity level. Increasing salinity level led to an increase in the amount of Na+ in shoot dry matter, while the amount of Ca+2 and K+ and Ca+2/Na+ and K+/Na+ ratios were decreased. The Yazd cultivar had the highest mean plant height (20.1 cm), shoot dry weight (1.94 g per plant) and number of leaves (13.4 per plant). Whereas, Shiraz cultivar had the highest amount of Ca+2 and K+ ions and also Ca+2/Na+ and K+/Na+ ratios. Based on the results of this research, it seems that Shiraz landrace, carrying genes related to salinity tolerance could be used to improve high yielding genotypes.

Abstract
In order to study the effects of salinity stress on morphological traits, essential oil content and ion accumulation in basil (Ocimum basilicum) plant under hydroponic conditions, a factorial experiment based on completely randomized blocks design with three replications was conducted on three landraces (Jahrom, Banafsh and Isfahan) and five NaCl salinity levels (0, 40, 80, 120 and 160 mM) in controlled greenhouse conditions. The results indicated a significant reduction in plant height, shoot dry weight and root dry weight due to increasing salinity level. Among the landraces, Banafsh landrace had the highest biomass. Also, with the increase in salinity level, sodium ion content of shoot and root increased. However, Ca2+ and K+ contents and Ca2+/Na+ and K+/Na+ ratios of both shoot and root decreased. These ratios were higher in shoots, as compared to roots, of all three landraces. Essential oil content increased with the increase in stress level. However, this much increase in essential oil content is not important at high salinity levels due to high reduction in biomass. This could be important at moderate stress considering produced biomass. Among the studied landraces, Jahrom landrace contained the highest essential oil content.
