Germination Kinetics and Seed Reserve Mobilization in Two Flax (Linum usitatissimum L.) Cultivars under Moderate Salt Stress

Germination Kinetics and Seed Reserve Mobilization in Two Flax (Linum usitatissimum L.) Cultivars under Moderate Salt Stress

Because of its high contents of protein, α-linolenic-rich oil, lignans, and fiber, demand is increasing for flax (Linum usitatissimum L.) and flax seed oil as a food source. In this comparative survey, we examined germination and the mobilization of seed storage products (lipids and soluble proteins...

Zusammenfassung:Because of its high contents of protein, α-linolenic-rich oil, lignans, and fiber, demand is increasing for flax (Linum usitatissimum L.) and flax seed oil as a food source. In this comparative survey, we examined germination and the mobilization of seed storage products (lipids and soluble proteins) of 3-d-old seedlings from two flax cultivars (N 51 and H 52) challenged with moderate salinity (up to 200 mM NaCl). At the highest salt concentration, germination appeared to be cultivar-dependent, with that of 'N 51' being less impaired and delayed than in 'H 52'.
