Longifolia, grown in salt stress conditions had a higher fresh yield (+65 % for highest dose), had a significant higher dry weight, had significant more chlorophyll, the same amount of sugars, significant more carotenoids, significant less nitrates, the same amount of proline and less Na compared to the untreated control plants grown in the same salt stress conditions
