摘要

The growth and mineral nutrition were investigated in seedlings of two cereals, durum wheat and barley, cultivated in nutritive solutions containing 0 or 100 mM NaCI. Salt decreased total dry weight of the two cereals. However, barley differed from wheat by a higher salt tolerance of the shoots. Na ~+ uptake and transport increased in the presence of NaCI, but Na ~+ accumulation in young leaves was lower in wheat than in barley. Barley was also distinguished by a good ability to sequestred Na~+ inside the vacuole, which might play a role in osmotic adjustement under saline conditions. wheat - barley - growth - salinity - tolerance.
