Unidirectional Na+ influx under different growth stages of Puccinellia tenui f lora and wheat
Restricting unidirectional Na+ influx into root was an important way to reduce the net accumulation of Na+.However, there was no report regarding whether the unidirectional Na+ influx was affected by the growth stage.Consequently, it was hard to compare the influxes between/among different growth stages or species.This study was focused on this problem.Thus, Gramineous halophyte P.tenui f lora and glycophyte wheat were chosen, for testing the unidirectional Na+ influxes of seedlings at the 2 leaf, 3 leaf and 4 leaf stages in 25 and 100 mM NaCl treatments.
